使用 GPT-6 Astra
瞭解 GPT-6 Astra 的最佳實務、功能與遷移指引。
簡介
GPT-6 Astra 是我們迄今最聰明的模型,在操作電腦、瀏覽網頁、軟體工程、科學與專業工作方面都具備頂尖表現。它擅長跨程式碼、瀏覽器與專業軟體執行多步驟工作流程。在多項評估中,Astra 不僅取得更好的結果,使用的輸出 Token 也大幅減少。因此,儘管每個 Token 的定價較高,每項任務的預估 API 成本仍低於先前的模型。
GPT-6 Astra 也是我們迄今對齊程度最高的模型。它擅長審慎行事、遵守任務範圍,並以透明的方式溝通。當指示留有解釋空間時,它會根據已有的上下文補足一般細節;若某個答案可能改變結果,則會提出有針對性的問題。它能納入新需求、依要求調整方向,並在回答額外問題時,仍掌握整體任務。
若要使用 Astra 開發,請在 Responses API 請求中將 model 設為 gpt-6-astra。
最新消息
- 非同步工具呼叫: 當應用程式執行工具時,GPT-6 Astra 可以繼續推理、呼叫其他工具,或回答請求中互不相依的部分。在函式或自訂工具上設定
async: true,並在結果準備就緒時,使用原始的call_id傳回結果。工具仍由應用程式執行,待完成的工作也仍由應用程式管理。如需基本用法及由開發者定義的等待工具模式,請參閱非同步工具呼叫。 - 回合中調整方向: 在 GPT-6 Astra 工作期間傳送額外的使用者指示,例如更正內容或變更需求。透過 WebSocket 連線,Responses API 會保留已完成的工作,並在接續執行時納入更新。如需事件流程與工具結果處理方式,請參閱回合中調整方向。
- 在對話中途變更推理並保留快取: 新增
configuration_update輸入項目,即可針對困難工作提高推理強度,或針對例行後續工作降低推理強度,無須重寫原始提示詞前綴。更新後的推理強度會持續生效,直到另一個configuration_update輸入項目將其覆寫。如需範例與相容性資訊,請參閱在對話中途變更推理。 - 失準監控: 我們為 GPT-6 Astra 強化的防護措施包括由系統以非同步方式監控失準情況,並在必要時觸發警示。如需詳細資訊,請參閱失準監控。
- 限制: GPT-6 Astra 不支援
none推理強度。使用歐盟資料駐留時,GPT-6 Astra 無法使用快速模式。
GPT-6 Astra 也支援 GPT-5.6 現有的 API 功能,包括電腦、結構化輸出、串流、以程式呼叫工具、多智慧體編排、提示詞快取、持久保留推理、壓縮及 Pro 模式。
提示詞最佳實務
GPT-6 Astra 比 GPT-5.6 Sol 等先前的模型更聰明、能力更強。它也有一些特定的行為模式,可以透過提示詞加以調整,以符合你的使用情境。
GPT-6 Astra 的行為
- 主動性與貫徹執行:模型的設計目標是成為更有效的協作夥伴,因此,當額外資訊可能大幅改變結果時,它更傾向向使用者提問。這可能導致模型停下來,即使使用者原本期望它做出合理假設並繼續執行。
- 遵循指示:GPT-6 Astra 在一般指示遵循方面比我們先前的模型更強,讓你更能掌控它的行為。它也可能更容易受到技能及其他檔案(例如
AGENTS.md)中指示的影響。我們 強烈建議 檢查模型可存取的技能及其他檔案,找出可能影響其行為的指示。 - 個性與寫作風格:模型傾向提供詳細且經過格式編排的回覆,也可能在不同工作階段反覆使用相同措辭。請明確指定應用程式需要的寫作風格與結構。
- 委派給子代理程式:模型委派工作的頻率可能低於工作流程所需。請明確指定它應在何時使用子代理程式進行平行作業,以及使用程度。
- 測試與驗證:處理程式碼編寫任務時,模型傾向先進行周全的測試,才認定任務完成。對於較小的任務,這可能導致測試範圍超出實際需要。
主動性與貫徹執行
在長時間任務中,GPT-6 Astra 通常比 GPT-5.6 Sol 及更早的模型更能維持思路連貫。遇到先前模型會自行做出假設的情況時,它也更傾向要求釐清。
若要鼓勵模型更自主地工作,可以從這段提示詞開始:
You should infer the user's intent and task scope from the instructions and prior conversation context. Your job is to bias towards action and carry the user's intended task to completion.
When the user expresses intent to perform new work or fix an existing issue, persist until the user's intended goal is complete. Progress autonomously towards the user's goal (e.g. creating isolated worktrees / checkouts if needed, resolving merge conflicts, read-only actions, creating draft PRs etc.) unless they are clearly destructive or irreversible.
當使用者的意圖不明確時,模型更傾向先向使用者釐清,再繼續執行。請透過提示詞告訴模型,若使用者的提示詞已隱含授權,就應繼續完成工作:
When the user's prompt indicates a request for action, such as "can you...", "I want to...", "help me..." and similar expressions, treat these as instructions to do the work and take action. Do not stop at acknowledging capability (e.g. "Yes…"), proposing a plan, or offering to continue. Do not settle for a partial or "helpful enough" solution that does not fully satisfy the user's task to save time, effort or tokens. If a task requires sustained work, complete all the necessary work until the intended outcome is fulfilled.
請透過提示詞要求模型,先準備好具體、可供審查的成果,再要求核准。這能避免模型尚未完成可執行的工作就阻擋任務進度,也往往能更快完成任務。
Before asking the user clarifying questions, you should complete the work that is already authorized from context and necessary to make the proposed action concrete and reviewable. The user should be approving a concrete, reviewable result. For example, before deploying a change, writing to an external application, merging a PR or publishing a site, do all the required work first so that user approval is the final step. You don't need user permission for reversible tasks, read-only actions, reviews or fixes, or anything for which authorization is provided earlier in the session or strongly implied from the task instruction.
Do not introduce unsolicited warnings, disclaimers, approval flows, or safety/compliance checklists due to hypothetical risk.
模型預設也傾向在工作期間提出不會阻擋進度的問題,因此請依應用程式所需的自主程度調整這些提示詞。
遵循指示
GPT-6 Astra 更能遵循較長的指示,但也可能更容易受到上下文資訊的影響。例如,技能檔案中的指引若不清楚或互相衝突,可能導致模型提早暫停,阻擋工作進度。請明確說明使用者指示與技能之間的優先順序。
The user's instructions take precedence over guidelines provided in a skill. If explicit user instructions conflict with a skill's instructions, prioritize the user's instructions.
要求模型指出導致它暫停或改變方向的技能與指示,也能有效提高模型行為的透明度。
If a skill causes you to ask for permission or confirmation, pause, leave requested work unfinished, or diverge from the user's intent, name and link to the exact SKILL.md file you read, quote the relevant instruction, and briefly explain how it applies. Distinguish explicit skill requirements from your interpretation of guidelines.
當應用程式載入許多技能及 AGENTS.md 等指示檔案時,可使用這段提示詞找出未明說卻已影響行為的指引,以及互相衝突的指引。
個性與寫作風格
GPT-6 Astra 傾向使用清單、表格與 Markdown,讓回覆便於快速瀏覽。如果應用程式需要格式較少的敘述文字,請明確說明這項偏好。
Default to using clear, concise paragraphs, each developing one main idea. Use lists only when the information is genuinely parallel, sequential, or easier to compare, and avoid nested lists unless the hierarchy cannot be expressed clearly in prose. Use plain, simple language: familiar words, concrete examples, and precise verbs. Prefer active voice and direct statements.
Make sure to state the main point clearly and early, then develop it with the explanation and detail the reader needs. Let each sentence build on what came before. Develop the points that matter and provide enough support to be useful.
在技術溝通中,以下提示詞有助於讓文字清楚、連貫,同時符合專業領域的用語習慣:
Use plain language over jargon, and reference technical details only to the degree that it helps illustrate an idea or your work to the user. Communicate complex concepts in a clear and cohesive manner, and calibrate your writing to the level of background knowledge assumed from the user's prompt and context.
若要減少文章中的行話與制式措辭,可以從這段提示詞開始:
Avoid using slop words or phrases like "Bottom Line:" in conclusions, "delve," "foster," "leverage," "it's worth noting," "importantly," "Question? Answer." or "This isn't about X. It's about Y.", "genuinely" or hyphenated compound descriptions and adjectives. Do not use concluding summary statements such as "In short:..", "The simplest mental model is:...".
State the intended action directly. Avoid adding what you won't do, what will remain unchanged, or how you'll separate or categorize results. Do not use contrastive framing such as "X, not Y" or "X—not Y" that introduces an unprompted alternative that the user didn't ask about. Avoid invented compound labels like "exact-head checks" and "editorial-row layouts", vague qualifiers, and canned transitions; use plain verbs and prepositions to state the actual relationship directly.
委派給子代理程式
GPT-6 Astra 經過訓練,能將工作拆分並委派給平行作業的子代理程式。如果你正在任務執行框架中實作多智慧體系統,可使用以下提示詞調整 GPT-6 Astra 委派工作的程度:
If at any point you can parallelize work by delegating tasks to another agent (no matter if you are the root or subagent), you should do so using collaboration tools if it could save time or improve quality.
智慧體之間的訊息可能包含文法或空格錯誤。使用這段提示詞,讓智慧體間的訊息更容易閱讀:
Messages that you send to other agents and your final answer may be read by a human, so ensure they are legible. Always put proper spaces between words and/or numbers.
透過提示詞說明應如何及何時將工作委派給子代理程式,通常能有效調整模型的行為。請依你的任務執行框架與多智慧體實作方式加以調整。
測試與驗證
處理程式碼編寫任務時,請依變更的需要調整測試與驗證的程度。這有助於避免為小幅變更進行不必要的測試或重複檢查。
Do not write tests for reversible, low-impact changes that mirror the implementation. If you do choose to verify your work with tests, make sure that the tests are meaningful and necessary to verify implementation.
Run tests appropriate to the change and complete required checks. Once those pass, broaden or repeat testing only when new changes, failures, or unresolved concerns justify it; otherwise, continue toward completing the task.

更新 API 與模型參數
將 model 設為 gpt-6-astra,然後檢查以下項目:
- 推理強度: 如果目前使用
none或minimal,請先從low開始,並比較結果。否則,請保留目前實際生效的推理強度。在 Responses 中使用reasoning.effort,在 Chat Completions 中則使用reasoning_effort。 - 工具呼叫: 請使用 Responses API。GPT-6 Astra 支援 Chat Completions,但工具呼叫必須使用 Responses。
- 不支援的參數: 移除
temperature、top_p和top_logprobs。若使用 Chat Completions,也請移除logprobs。若使用 Responses,請從include中移除message.output_text.logprobs。 - 快速模式: 使用歐盟資料駐留時,請採用標準處理。在歐盟資料駐留設定下,GPT-6 Astra 不支援
service_tier: "fast"或service_tier: "priority"。GPT-6 Astra 的快速模式不包含延遲 SLA。請參閱快速模式相容性。 - 變更推理強度: 如果應用程式會在不同回覆之間變更推理強度,請在標準的單一智慧體請求中使用
configuration_update項目。請保持請求層級的reasoning.effort不變,以保留提示詞前綴供快取使用。採用此功能前,請先查看相容性限制。 - 提示詞快取: 從 GPT-5.5 或更早的版本遷移時,請以
prompt_cache_options.ttl取代prompt_cache_retention,並將其設為"30m"。請查看提示詞快取的變更,包括快取邊界與快取寫入計費方式。 - 不必要的核准等待: 如果模型反覆要求核准才繼續執行,請依照主動性與貫徹執行的指引調整提示詞,讓它更自主地執行。關於遵循指示、寫作風格、委派給子代理程式及測試的指引,請參閱提示詞最佳實務的其餘內容。
使用 GPT-5.6
瞭解 GPT-5.6 與 GPT-5.6 模型系列的最佳實務、功能及遷移指引。
簡介
GPT-5.6 為複雜的正式環境工作流程樹立了新的品質與效率基準。GPT-5.6 的 Token 使用效率尤其出色,前端美感也有所提升,包括版面配置、視覺層次和設計判斷。
GPT-5.6 也引入了新的命名方式。gpt-5.6 別名會將請求導向具備旗艦級能力的模型 gpt-5.6-sol。若要以較低價格獲得出色效能,請使用 gpt-5.6-terra;若要高效率地處理大量工作,請使用 gpt-5.6-luna。
從 GPT-5.5 或 GPT-5.4 遷移時,請先沿用目前的 GPT-5.5 或 GPT-5.4 推理設定,再以具代表性的任務測試相同設定及低一級的設定。GPT-5.6 通常能以較少的 Token 維持或提升品質,但最佳設定仍取決於你的工作負載。
最新消息
- 以程式呼叫工具: GPT-5.6 可以撰寫 JavaScript 來呼叫符合條件的工具、在各次呼叫之間傳遞結果,並在託管執行環境中處理中間輸出。對於範圍明確、需大量使用工具,且不需要模型在每個步驟之間重新判斷的工作流程,請使用以程式呼叫工具。以程式呼叫工具與 ZDR 相容,且不會產生額外的容器費用。
- 多智慧體 [beta]: 多智慧體讓一個 GPT-5.6 執行個體能協調多個子代理程式平行工作,並整合其結果。這與 Codex 的 Ultra 模式類似,對於能明確拆分為獨立工作項目的複雜任務,可以縮短實際經過時間並提升效能。多智慧體目前以 beta 功能形式在 Responses API 中提供,我們會持續根據開發者的回饋改進。
- 明確提示詞快取: GPT-5.6 讓你能精確標記要由 OpenAI 快取的可重複使用提示詞前綴。你仍可在隱含模式下使用自動快取。OpenAI 的快取寫入費率為未快取輸入費率的 1.25 倍,而快取讀取仍享有折扣。瞭解如何設定提示詞快取。
- 保留推理內容: GPT-5.6 可以跨回合重複使用可用的推理項目,提升多回合互動的品質與快取效率。使用
reasoning.context選擇其行為。瞭解如何在各次呼叫之間保留推理內容。 - Max 推理強度: GPT-5.6 支援
max推理強度,適用於需要更多探索與驗證的高難度任務。如果你目前使用xhigh,請以具代表性的工作負載比較這兩種設定。 - Pro 模式: GPT-5.6 可以投入更多模型運算,提高處理困難任務的可靠性,並傳回單一最終答案。當品質比延遲和 Token 用量更重要時,可透過
reasoning.mode: "pro"啟用此模式。瞭解如何使用 Pro 模式。 - Token 使用效率: GPT-5.6 能以較少的輸出 Token 達到旗艦級效能。
- 前端設計: GPT-5.6 在版面配置、視覺層次和設計判斷方面表現更佳,能建立更精緻、易用的網站與應用程式。
- 意圖理解: GPT-5.6 能更準確地從上下文推斷使用者的真正目標,以及預期工作應做到什麼程度,因此通常不必逐步指定做法。仍請提供領域背景、不可違反的限制、核准界線和成功標準,並告訴模型,遇到哪些重要歧義時應先提問。
- 原始圖像細節: 使用
original或auto細節設定時,GPT-5.6 會保留圖像尺寸;但任一邊超過 65,535 像素的圖像會縮小至符合該限制。若圖像仍超過30,000 個圖像區塊的限制,API 會拒絕該圖像,而不會再調整尺寸以符合限制。大型圖像可能使用更多輸入 Token 並增加延遲。瞭解如何選擇圖像細節等級。
防護措施
使用 GPT-5.6 模型時,系統會在生成模型輸出的同時執行即時網路與生物濫用分類器,因此使用者的部分請求可能遭到防護措施封鎖或拒絕。其他請求可能需要更長時間,因為這些分類器會同步審查輸出,使生成過程中途暫停數秒。防護措施偶爾也可能介入正當工作,尤其是在防禦與攻擊活動起初可能看起來相似的雙重用途領域。
如果你的應用程式為個別終端使用者提供服務,請在每次請求中傳送穩定且能保護隱私的 safety_identifier。相關指引請參閱實作安全識別碼。
我們持續改進這些防護措施,使其能穩健、有效地抵禦對抗性壓力,同時保留程式碼審查、漏洞研究、修補程式開發、偵錯、資安教育和防禦性測試等正當工作的使用管道。

更新 API 與模型參數
- 根據工作負載選擇目標模型。若需要旗艦級能力,請使用
gpt-5.6-sol;若要兼顧智慧與成本,請使用gpt-5.6-terra;若要高效率地處理大量工作,請使用gpt-5.6-luna。gpt-5.6別名會將請求導向gpt-5.6-sol。 - 針對推理、工具呼叫和多回合工作流程,請使用 Responses API。
- 請根據需求設定
reasoning.effort。GPT-5.6 支援none、low、medium、high、xhigh和max。- 如果你正從 GPT-5.5 或 GPT-5.4 遷移,請保留目前的推理強度作為基準,再與低一級的設定比較。
- 如果你使用
none,請將其保留為延遲基準;若推理或工具使用有助於工作流程,也請測試low。 - 以
medium作為均衡的起始設定;對於延遲敏感的工作負載,則使用low。 - 若實測顯示更多推理能提升品質,請使用
high或xhigh。 - 僅在最困難且以品質為優先的工作負載中使用
max。比較max和xhigh,找出最適合你使用案例的品質、延遲與成本平衡。
- 若要使用 Pro 模式,請保留已選取的 GPT-5.6 模型,並在 Responses API 中將
reasoning.mode設為pro;不要切換至另一個 Pro 模型 Slug。請獨立選擇reasoning.effort。如果省略此設定,GPT-5.6 在標準模式與 Pro 模式下都預設為medium。請參閱推理模式,查看請求範例和計費詳細資訊。 - 請根據先前推理內容仍有多少與當前任務相關,設定推理保留方式。GPT-5.6 模型預設為
all_turns;較早的模型則預設為current_turn。- 省略
reasoning.context或將其設為auto,即可使用 GPT-5.6 的預設值all_turns。請檢查回應中的reasoning.context欄位,確認實際生效的模式。 - 當任務的目標、假設和優先順序在各回合之間保持穩定時,請將
reasoning.context設為all_turns。 - 使用
all_turns時,請透過previous_response_id延續對話,讓模型能使用先前回應中的推理內容。 - 手動管理歷史紀錄時,請保留並重新傳送先前的使用者輸入,以及每一個回應輸出項目。若使用
store: false或零資料保留,請重新傳送 API 預設傳回的加密推理項目。 - 當先前的推理內容不再相關時,請將
reasoning.context設為current_turn。
- 省略
- 檢視提示詞快取設定。你不需要修改程式碼,就能繼續使用隱含快取。由於 GPT-5.6 的快取寫入費率為未快取輸入費率的 1.25 倍,請追蹤
cached_tokens和cache_write_tokens,以瞭解淨成本。使用明確斷點或prompt_cache_options.mode: "explicit"避免不必要的寫入,並將prompt_cache_retention替換為prompt_cache_options.ttl。 - 若要使用以程式呼叫工具,請新增
programmatic_tool_calling工具,並透過allowed_callers允許符合條件的工具參與。更新應用程式,使其能處理program項目、程式發起的函式呼叫,以及program_output項目,同時保留每次呼叫的call_id和caller關聯。請參閱以程式呼叫工具指南,查看請求與延續執行的範例。- 以具代表性的任務,對已啟用 PTC 的工作流程進行基準測試。比較任務成功情況、最終答案的完整性、所需證據、Token 總量、延遲和成本。只有在最終答案仍達到所需品質標準時,減少呼叫次數、回合數或中間輸出才算是改善。
提示詞最佳實務
優先使用精簡的提示詞
移除重複的指示與範例,並簡化工具說明,可以改善任務表現與 Token 使用效率。在一組內部程式碼編寫智慧體的評估執行樣本中,採用較精簡系統提示詞的組態讓評估分數提高約 10–15%,同時將 Token 總量減少 41–66%、成本降低 33–67%。結果會因工作負載而異,因此請將這些範圍視為趨勢參考,並以你自身應用程式中具代表性的任務驗證變更。
若要在不遺漏重要指引的情況下簡化提示詞:
- 從已有效運作的提示詞與工具組合開始。每次移除一組指示、範例或工具,再重新執行相同的評估。
- 每項指示只說一次。
- 只提供與任務相關的工具,並讓工具說明保持簡潔、精確。
- 若範例與風格指引承載了產品需求,或能修正實測發現的不足,請予以保留。
- 在開始執行時,以及對話逐漸增長的過程中,都要追蹤上下文。長時間的對話可能放大重複提示詞與工具內容的影響。
界定自主行動與核准的界線
GPT-5.6 在執行多步驟任務時,可以主動且持續地推進工作。請界定每項請求授權的行動程度,讓模型能持續執行安全且符合範圍的工作,避免不必要的暫停,同時在採取對外、破壞性、高成本或擴大範圍的行動前停下。
通常只需要一份簡潔的政策:
For requests to answer, explain, review, diagnose, or plan, inspect the relevant
materials and report the result. Do not implement changes unless the request also
asks for them.
For requests to change, build, or fix, make the requested in-scope local changes
and run relevant non-destructive validation without asking first.
Require confirmation for external writes, destructive actions, purchases, or a
material expansion of scope.
明確列出安全的本機操作,例如讀取檔案、檢查記錄、編輯範圍內的程式碼和執行測試。將政策集中在一處,每項規則只說一次。重複「先詢問」、「不要變更」或「等待核准」等指示,可能導致模型在執行安全且符合預期的操作時,也提出不必要的核准請求。
設定回應長度與風格
GPT-5.6 的預設回應通常比 GPT-5.5 更簡潔。遷移時,請檢查「請簡潔作答」或「保持簡短」等籠統的簡短指示是否仍有用。對某些任務而言,這些指示可能沒有必要,有時還會使回應過於簡略。若這些指示能穩定產生應用程式所需的輸出,則請保留。
若要在不同請求之間維持更一致的控制,請使用 text.verbosity 設定預設的詳細程度,再於提示詞中指定個別任務的需求。
使用 text.verbosity 設定預設值
選擇 low、medium 或 high,作為請求的預設詳細程度。在提示詞中指定個別任務所需的長度、結構或必要內容。API 範例請參閱設定 text.verbosity。
明確指定簡短答案必須包含的內容
當任務需要較短的回答時,請明確指出模型必須保留哪些資訊,以及可以省略哪些細節。例如:
Lead with the conclusion. Include the evidence needed to support it, any material
caveat, and the next action. Omit secondary detail and repetition.
Keep all required facts, decisions, caveats, and next steps. Trim introductions,
repetition, generic reassurance, and optional background first.
這能讓模型清楚掌握優先順序:先保留完成任務所需的內容,再刪除價值較低的細節。
定義語氣
「友善」或「有同理心」等籠統描述可能不夠明確。請具體說明構成產品語氣的寫作方式,例如回答應該多直接、何時應表達對問題的理解,以及是否適合加入安撫語句或結語。
State the answer directly. If the user reports a problem, acknowledge the
specific issue before giving the next step. Use reassurance only when it is
relevant. Omit generic praise and unnecessary sign-offs.
Pro 模式
品質最重要時,選擇 Pro 模式
Pro 模式是 Responses API 的一種執行模式,會讓模型針對請求投入更多運算,再傳回單一最終答案。這可提升處理困難任務時的可靠性,但也會增加延遲,且回報的用量會彙總這些運算所使用的 Token。這些 Token 會依所選模型的標準 Token 費率計費。
如果品質即使只略微提升,也會對結果產生實質影響,而且任務難度足以從中受益,就適合使用 Pro 模式。例如複雜的最佳化、高價值的程式碼編寫或審查,或具備明確評估標準的深入分析。對於例行、對延遲敏感或處理量大的工作,以及評估未顯示 Pro 模式帶來明顯改善的情況,請優先使用標準模式。
推理模式與推理強度彼此獨立。Pro 模式可搭配任何 GPT-5.6 模型及其支援的推理強度。請先採用與標準模式基準相同的模型和推理強度,再以具代表性的任務比較各種組態,不要假設最高推理強度總是最佳取捨。
在 API 中設定 Pro 模式
請在 API 請求中啟用 Pro 模式。沿用標準模式下以成果為導向的提示詞:說明目標、相關上下文、限制、必要證據、成功標準和輸出格式。你不需要要求模型「使用 Pro 模式」、「更深入思考」,或產生多個候選答案。
例如:
Review this database migration plan for failure modes that could cause data loss
or extended downtime. For each finding, cite the relevant step, estimate impact
and likelihood, and recommend a specific mitigation. Return the five most
important risks in severity order.
比較品質與成本
以相同且具代表性的任務比較標準模式與 Pro 模式。衡量任務成功率、答案完整性、必要證據、Token 總數、延遲和成本。只有在品質或可靠性的提升值得投入額外模型運算時,才選擇使用 Pro 模式。
詳情請參閱推理模式指南。
以程式呼叫工具
依任務特性決定是否以程式呼叫工具
以程式呼叫工具(PTC)最適合範圍明確的工作流程:程式碼可以處理多個工具結果或大量中間輸出,再傳回小得多的結構化結果。可用於篩選、聯結、排序、去除重複資料、彙總、驗證,或其他處理方式可預先確定的作業。
僅因為需要多次、平行或有相依關係的呼叫,並不足以構成以程式呼叫工具的理由。遇到下列情況時,請優先採用直接工具呼叫,不使用 PTC:
- 一次呼叫就足夠
- 中間輸出本來就很少
- 每個結果都可能改變模型的下一步決策
- 某項動作需要核准
- 最終輸出必須保留引用來源或原生產出
針對任務明確指定呼叫方式
不要只靠工具是否可用,或「有效率地以程式呼叫工具」這類泛用指示,來讓模型選擇正確的呼叫方式。當直接呼叫與以程式呼叫兩種方式都可用時,請明確說明:
- 哪個範圍明確的階段應以程式呼叫工具。
- 可以呼叫哪些工具。
- 確切的輸出結構描述與必要證據。
- 並行數與重試次數的限制,以及停止條件。
- 哪些工作應維持直接呼叫。
工具說明應記載預期傳回的欄位、型別,以及發生錯誤時的行為。如果模型在撰寫程式前無法確定回傳資料的結構,請優先採用直接工具呼叫,讓模型先檢視結果,再決定如何使用。
如果兩種呼叫方式都需要,請定義一個明確的交接點,並告訴模型不要切換呼叫方式或重複已完成的工作。
例如:
<tool_orchestration>
Use Programmatic Tool Calling for [bounded stage] using only [eligible tools].
Run independent calls concurrently when safe. Use only documented tool input
and output fields.
Process and reduce the intermediate results, then emit exactly [output schema],
including the evidence needed for the final answer.
Stop when [condition] is met. Retry transient failures at most [R] times.
Do not repeat completed calls or perform side-effecting actions. If a required
result is still missing, return a clear structured failure.
Use direct tool calls for [semantic judgment, approval, or final validation].
</tool_orchestration>
評估最終答案
program_output 項目與助理的最終 message 是各自獨立的輸出;請務必測試兩者。理論上,程式可能傳回正確的記錄,但訊息卻遺漏必要欄位、引用來源或注意事項。
以相同且具代表性的任務比較直接呼叫與以程式呼叫。檢查最終回應是否正確、完整,並包含必要證據。接著比較 Token 總數、延遲、成本、呼叫次數、回合數與重試次數。只有在回應仍通過既有評估時,才能將資源用量降低視為改善。
詳情請參閱以程式呼叫工具指南。
使用 GPT-5.5
瞭解 GPT-5.5 的最佳實務、功能與遷移指引。
簡介
GPT-5.5 提升了複雜正式環境工作流程的基本表現。它非常適合程式碼編寫、大量使用工具的智慧體、提供有據可查回答的助理、長上下文檢索、將產品規格轉為計畫的工作流程,以及對執行品質與回應表達品質要求嚴格的客戶服務工作流程。
若要充分發揮 GPT-5.5 的能力,請將它視為需要重新調校的新模型系列,而非可直接替換 gpt-5.2 或 gpt-5.4 的模型。開始遷移時,請建立新的基準,不要照搬舊版提示詞組合中的每一項指示。先使用能維持產品既定行為要求的最精簡提示詞,再以具代表性的範例調校推理強度、回應詳盡程度、工具說明與輸出格式。
GPT-5.5 支援 GPT-5.4 已提供的所有 API 功能,包括提示詞快取、託管工具、工具搜尋、壓縮,以及手動重播助理項目時的 phase 處理。
如需有效提示詞模式的範例,請參閱提示詞最佳實務。
最新消息
- 更有效率的推理: 即使採用相同的推理強度,GPT-5.5 也能以比先前模型更少的推理 Token 取得出色成果。這對複雜、大量使用工具或多步驟的工作流程尤其有用,因為節省的 Token 會逐步累積。
- 以成果為導向的提示詞可提升任務執行表現: GPT-5.5 更擅長依據明確目標展開工作、遵守限制,並將產品意圖轉為具體的後續步驟。請說明預期成果、成功標準、允許的副作用、證據規則與輸出形式。除非特定執行路徑很重要,否則請避免逐步指導流程。
- 工具使用能力更強、更精準: GPT-5.5 特別適合工具種類繁多的環境、多步驟服務工作流程,以及長時間執行的智慧體任務。它在工具選擇與引數使用上通常更為精準。
- 語氣通常更流暢得體,但也可能更直接: GPT-5.5 通常只需較少的提示詞引導,就能產生更親切、更易讀的回答。

medium: GPT-5.5 預設採用medium推理強度。建議以medium作為兼顧品質、可靠性、延遲與成本的起點。對延遲敏感的工作流程,如果工具使用、規劃、搜尋或多步驟決策仍然重要,請先評估low,再考慮none。none僅適用於對延遲要求極高,且不需要推理或多次串接工具呼叫的任務,例如輕量語音互動、快速資訊檢索與分類。只有在評估顯示品質有可衡量的提升,足以抵銷額外延遲與成本時,才提高至high或xhigh。如需建議設定的詳細資訊,請參閱推理模型文件。推理強度越高,不一定越好。如果任務中的指示互相衝突、停止標準不明確,或工具存取範圍未設限,提高推理強度可能導致過度思考、不必要的搜尋,或輸出品質下降。只有在評估顯示品質有可衡量的提升時,才提高推理強度。
-
圖像輸入預設保留更多視覺細節: GPT-5.5 更新了圖像輸入的預設處理方式,以保留更多視覺細節,並提升電腦操作表現。當
image_detail未設定或設為auto時,模型現在會採用original的處理方式:在達到 10,240,000 像素或單邊 6,000 像素的上限前,保留圖像原始尺寸。若要使用high,請直接指定此值;在達到 2,500,000 像素或單邊 2,048 像素的上限前,它會保留圖像原始尺寸。low現在著重於上下文使用效率,對於單邊超過 512 像素上限的圖像,會比先前模型更積極地縮小尺寸。請參閱圖像與視覺文件。 -
更能遵循指示: GPT-5.5 會依字面意思完整解讀提示詞,因此當產品有需要時,您可以提供具體、描述性的指示。請定義成功標準與停止規則,尤其是長時間執行、大量使用工具或蒐集證據的工作流程。請參閱撰寫以成果為導向的提示詞與維持適當的具體程度。
-
預設風格更精簡直接: GPT-5.5 的預設風格通常有效率、直接,且以任務為導向。這對許多正式環境工作流程很有幫助,但面向客戶或對話式的體驗,可能需要明確指引個性、親切程度、理由說明與格式。請依需求設定
text.verbosity:預設值為medium;若希望回應精簡,low通常是更好的起點。請參閱提示詞最佳實務。 -
程式碼編寫工作流程需要更完善的編排: GPT-5.5 更適合需要規劃、使用工具、瀏覽程式碼庫、驗證與多步驟執行的複雜程式碼編寫任務。對程式碼編寫智慧體,請明確說明重用原則、子代理程式委派、測試要求、驗收標準,以及何時應繼續工作、何時應尋求協助。

API 與模型參數
- 將模型 Slug 更新為
gpt-5.5。 - 所有涉及推理、工具呼叫或多輪互動的使用案例,都請使用 Responses API。
- 調校
reasoning.effort。使用low進行高效率推理;使用medium在延遲與效能之間取得平衡;對需要高難度推理、且延遲較不重要的複雜智慧體任務,使用high;對最困難的非同步智慧體任務,或測試模型智慧極限的評估,使用xhigh。請參閱推理模型文件。 - 若要讓回應更精簡,請將
text.verbosity設為low。在 GPT-5.5 上,此設定產生的回應會比 GPT-5.4 採用low詳盡程度時相對更精簡。 - 對於大量使用工具或長時間執行的工作流程,請確認應用程式能正確處理
phase、開場說明與助理項目重播。 - 針對準確度、Token 用量與端到端延遲,與其他模型進行基準比較。
提示詞
- 明確說明預期成果與成功標準。
- 減少或移除詳細的逐步流程指引。除非產品要求特定執行路徑,否則讓 GPT-5.5 自行選擇。
- 盡可能從提示詞中移除輸出結構描述定義,改用結構化輸出。
- 調整提示詞以提高快取效益:靜態部分放在前面,動態部分放在最後。
- 移除目前日期。模型已知道目前的 UTC 日期。
- 參照提示詞最佳實務,審查並最佳化您的提示詞。
使用推理模型
本指引適用於 GPT-5 系列模型。團隊每次將工作負載移至推理模型時,都適合重新檢視這些建議。GPT-5.5 延續了許多先前模型首次推出的能力;如果您正從較早的 GPT-5 模型、GPT-4.1 或 o3 等推理模型遷移,仍值得重新瞭解這些能力。
團隊可能會忽略這些功能,因為其中一部分涉及 API 組態與編排,而不在提示詞本身。搭配使用 Responses API、推理控制、回應詳盡程度、結構化輸出、提示詞快取、工具設計、託管工具與狀態管理,有助於推理模型在智慧、可靠性、延遲與成本方面達到最佳整體表現。
- Responses API: GPT-5.5 在 Responses API 中表現最佳。請使用
previous_response_id處理多輪互動的狀態。對於無狀態或零資料保留流程,請在每一輪傳回相關的已回傳輸出項目。詳情請參閱傳遞前一次回應的上下文。 - 推理強度: 使用
reasoning.effort選擇low、medium、high或xhigh。預設值為medium,但許多工作負載使用low就能有良好表現。none僅適用於低延遲比智慧更重要的使用案例。如需詳細建議,請參閱推理模型。 - 回應詳盡程度: 使用
text.verbosity控制輸出長度。請將最終回答長度與推理品質分開考量;視需要指定字數限制、章節數、表格寬度,或要求僅輸出 JSON。 - 結構化輸出: 避免在提示詞中描述預期的輸出結構描述。請使用結構化輸出來自動驗證並提高準確度。
- 提示詞快取: 提示詞快取會自動套用至符合條件的長提示詞,可降低延遲與輸入 Token 費用。若要盡可能提高快取命中率,請將固定內容放在請求開頭,並將依使用者而異的動態上下文放在接近結尾的位置。追蹤
usage.prompt_tokens_details.cached_tokens以衡量快取重用情況。對於共用可重用前綴的請求,請使用固定的prompt_cache_key。這個鍵有助於將相關請求路由至同一個快取,對於最佳化 GPT-5.5 的快取命中率相當重要。對於流量較大的請求群組,請遵循將流量分散至更多鍵的指引。 - 工具呼叫: GPT-5.5 支援與 GPT-5.4 相同的工具呼叫模式,包括函式工具與大量使用工具的智慧體工作流程。請將大多數工具專屬指引放在工具本身的說明中,包括工具的用途、使用時機、必要輸入、副作用、重試是否安全,以及常見錯誤情況。只有當工具專屬上下文適用於多種工具,或會實質改變智慧體的運作政策時,才將它加入系統指示。
- 託管工具與工具搜尋: 若符合工作流程需求,請優先使用 OpenAI 託管工具,例如網頁搜尋、檔案搜尋、程式碼解譯器、圖像生成與電腦操作。託管工具可減輕自行編排的負擔,並讓常見工具使用模式與 Responses API 及 Agents SDK 保持一致。若需要呼叫自己的系統、執行特定領域的副作用,或提供內部業務工作流程,請使用自訂函式工具。工具目錄規模較大時,可考慮使用工具搜尋延後載入工具定義,只載入相關的子集。
- 工具開場說明: 開場說明可改善對話的使用者體驗,讓使用者在模型產生最終回應之前,先看到有用的初步狀態更新。這也能讓工具使用過程更容易掌握:模型可以先說明即將檢查或執行的事項,等工具結果回傳後,再從同一個助理狀態繼續。
phase處理: 如果應用程式未使用previous_response_id,而是每輪傳回輸出項目來手動管理 Responses 狀態,請保留已回傳助理輸出項目上的phase參數,並原樣傳回。使用推理強度、開場說明或重複工具呼叫時,這點尤其重要。請參閱 Phase 參數。- 壓縮: 對於長時間執行的智慧體,請有意識地運用對話/狀態壓縮。保留已完成的動作、目前採用的假設、ID、工具結果、尚未解決的阻礙,以及下一個具體目標。
- Agents SDK: 建立新的智慧體系統時,請採用最新的 Agents SDK 模式來處理工具編排、追蹤、交接與狀態管理,不必從零開始重新建構編排機制。
- 目前日期: GPT-5.5 知道目前的 UTC 日期,您不需要在系統指示中加入目前日期。只有當應用程式需要業務特定時區、政策生效日期、使用者當地日期,或其他非 UTC 參考基準時,才加入明確的日期或時區上下文。
提示詞最佳實務
當提示詞定義了成果,並保留空間讓模型自行選擇有效率的解決方式時,GPT-5.5 的表現最佳。相較於先前模型,您通常可以使用更短、更以成果為導向的提示詞:說明理想成果、重要限制、可用證據,以及最終回答應包含的內容。
避免照搬舊版提示詞組合中的每一項指示。舊提示詞往往過度規定流程,因為先前模型需要更多引導才能保持方向。對 GPT-5.5 而言,這可能增加干擾、限縮模型探索解法的空間,或使回答過於僵化。
這裡的模式可作為起點。請根據產品介面、工具、評估與使用者體驗目標加以調整。
個性與行為
GPT-5.5 的預設風格有效率、直接,且以任務為導向。這對正式環境系統很有幫助:回應能保持聚焦、行為更容易引導,模型也會避免不必要的對話贅詞。
對於面向客戶的助理、客服工作流程、教練式互動體驗及其他對話式產品,請同時定義個性與協作風格。
- 個性 控制助理的表達方式,包括語氣、親切程度、直接程度、正式程度、幽默感、同理心,以及表達的精緻程度。
- 協作風格 控制助理的工作方式,包括何時提問、何時做出假設、應多主動、提供多少上下文、何時檢查工作成果,以及如何處理不確定性或風險。
這兩類指示都應保持簡短。個性指示應塑造使用者體驗,協作指示應塑造任務執行行為。兩者都不應取代明確目標、成功標準、工具規則或停止條件。
適用於穩健、專注任務的助理的個性設定區塊範例:
# Personality
You are a capable collaborator: approachable, steady, and direct. Assume the user is competent and acting in good faith, and respond with patience, respect, and practical helpfulness.
Prefer making progress over stopping for clarification when the request is already clear enough to attempt. Use context and reasonable assumptions to move forward. Ask for clarification only when the missing information would materially change the answer or create meaningful risk, and keep any question narrow.
Stay concise without becoming curt. Give enough context for the user to understand and trust the answer, then stop. Use examples, comparisons, or simple analogies when they make the point easier to grasp. When correcting the user or disagreeing, be candid but constructive. When an error is pointed out, acknowledge it plainly and focus on fixing it.
Match the user's tone within professional bounds. Avoid emojis and profanity by default, unless the user explicitly asks for that style or has clearly established it as appropriate for the conversation.
表達生動、善於協作的助理個性設定區塊範例:
# Personality
Adopt a vivid conversational presence: intelligent, curious, playful when appropriate, and attentive to the user's thinking. Ask good questions when the problem is blurry, then become decisive once there is enough context.
Be warm, collaborative, and polished. Conversation should feel easy and alive, but not chatty for its own sake. Offer a real point of view rather than merely mirroring the user, while staying responsive to their goals and constraints.
Be thoughtful and grounded when the task calls for synthesis or advice. State a clear recommendation when you have enough context, explain important tradeoffs, and name uncertainty without becoming evasive.
如果產品需要更生動的表達,可明確加入溫暖、好奇心、幽默或觀點等特質,但仍應保持區塊簡短。個性應用來塑造體驗,而不是彌補不明確的目標或缺少的任務指示。
透過開場說明縮短首個可見 Token 的等待時間
在串流應用程式中,使用者會注意第一段可見回應出現前需要等待多久。GPT-5.5 在輸出可見文字之前,可能會先花時間推理、規劃或準備工具呼叫。
對於耗時較長或大量使用工具的任務,請在提示詞中要求模型先提供簡短的開場說明:以使用者看得到的簡短進度訊息,確認已收到請求並說明第一步。這能在不改變任務本身的情況下,讓使用者感覺回應更即時。
當任務可能需要多個步驟、呼叫工具,或涉及長時間執行的智慧體工作流程時,可使用這種模式。
Before any tool calls for a multi-step task, send a short user-visible update that acknowledges the request and states the first step. Keep it to one or two sentences.
對於會區分訊息階段的程式碼編寫智慧體,可以下達更明確的指示:
You must always start with an intermediary update before any content in the analysis channel if the task will require calling tools. The user update should acknowledge the request and explain your first step.
以成果為先的提示詞與停止條件
提示詞若能明確定義目標成果、成功標準、限制條件與可用上下文,再讓模型自行選擇執行方式,GPT-5.5 就能發揮最佳表現。
對許多任務而言,應描述要達成的目標,而非逐一規定步驟。這能讓模型有空間選擇適合該任務的搜尋方式、工具或推理策略。
建議採用這種寫法:
Resolve the customer's issue end to end.
Success means:
- the eligibility decision is made from the available policy and account data
- any allowed action is completed before responding
- the final answer includes completed_actions, customer_message, and blockers
- if evidence is missing, ask for the smallest missing field
避免不必要的絕對規則。 舊版提示詞常使用 ALWAYS、NEVER、must 和 only 等嚴格指示來控制模型行為。這些用語應保留給真正不可變動的要求,例如安全規則、必要的輸出欄位,或絕不應執行的動作。對於需要判斷的情況,例如何時搜尋、要求釐清、使用工具或繼續反覆改進,則應優先提供判斷準則。
除非每個步驟都確實必要,否則請避免這種指示方式:
First inspect A, then inspect B, then compare every field, then think through
all possible exceptions, then decide which tool to call, then call the tool,
then explain the entire process to the user.
加入明確的停止條件:
Resolve the user query in the fewest useful tool loops, but do not let loop minimization outrank correctness, accessible fallback evidence, calculations, or required citation tags for factual claims.
After each result, ask: "Can I answer the user's core request now with useful evidence and citations for the factual claims?" If yes, answer.
定義缺乏證據時的處理方式:
Use the minimum evidence sufficient to answer correctly, cite it precisely, then stop.
格式
GPT-5.5 的輸出格式與結構可以透過指示靈活調整。當這有助於理解,或能讓輸出更符合產品需求時,請善用這項能力。
設定 text.verbosity 並描述預期的輸出形式。只有在更完整的結構有助於理解,或產品 UI 需要形式穩定的產出時,才採用這類結構。API 中 text.verbosity 的預設值為 medium;如果希望回應更短、更精簡,請使用 low。
簡單的對話式格式:
Let formatting serve comprehension. Use plain paragraphs as the default format for normal conversation, explanations, reports, documentation, and technical writeups. Keep the presentation clean and readable without making the structure feel heavier than the content.
Use headers, bold text, bullets, and numbered lists sparingly. Reach for them when the user requests them, when the answer needs clear comparison or ranking, or when the information would be harder to scan as prose. Otherwise, favor short paragraphs and natural transitions.
Respect formatting preferences from the user. If they ask for a terse answer, minimal formatting, no bullets, no headers, or a specific structure, follow that preference unless there is a strong reason not to.
加入明確的受眾與篇幅指引:
Write for a senior business audience. Keep the answer under 400 words. Use short paragraphs and only include bullets when they improve scannability. Prioritize the conclusion first, then the reasoning, then caveats.
處理編輯、改寫、摘要或面向客戶的訊息時,請先告訴模型哪些內容必須保留,再要求它改善文風。若只想潤飾而不增加篇幅,這種模式很有用。
Preserve the requested artifact, length, structure, and genre first. Quietly improve clarity, flow, and correctness. Do not add new claims, extra sections, or a more promotional tone unless explicitly requested.
接地、引用與檢索預算
若要產生有依據的回答,提示詞應包含引用方式的指示。請定義哪些內容需要佐證、什麼程度的證據才算足夠,以及缺乏證據時模型應如何處理。缺乏證據不應直接被當成足以確定事實的否定答案。如需更多詳細資訊與範例,請參閱引用格式指南。
加入明確的檢索預算
檢索預算是搜尋的停止規則,用來告訴模型何時已有足夠證據,可以停止搜尋。
For ordinary Q&A, start with one broad search using short, discriminative keywords. If the top results contain enough citable support for the core request, answer from those results instead of searching again.
Make another retrieval call only when:
- The top results do not answer the core question.
- A required fact, parameter, owner, date, ID, or source is missing.
- The user asked for exhaustive coverage, a comparison, or a comprehensive list.
- A specific document, URL, email, meeting, record, or code artifact must be read.
- The answer would otherwise contain an important unsupported factual claim.
Do not search again to improve phrasing, add examples, cite nonessential details, or support wording that can safely be made more generic.
創意撰稿的防護機制
對於撰稿任務,請告訴模型哪些主張必須有來源依據,哪些部分可以發揮創意。這對投影片、發表文案、客戶摘要、講稿要點、主管短文與敘事架構尤其重要。
For creative or generative requests such as slides, leadership blurbs, outbound copy, summaries for sharing, talk tracks, or narrative framing, distinguish source-backed facts from creative wording.
- Use retrieved or provided facts for concrete product, customer, metric, roadmap, date, capability, and competitive claims, and cite those claims.
- Do not invent specific names, first-party data claims, metrics, roadmap status, customer outcomes, or product capabilities to make the draft sound stronger.
- If there is little or no citable support, write a useful generic draft with placeholders or clearly labeled assumptions rather than unsupported specifics.
前端工程與視覺品味
進行前端工作時,請參考指示範例,了解引導 UI 品質的實用方法。這些範例涵蓋產品與使用者背景、與設計系統的一致性、首屏易用性、使用者熟悉的控制項、預期狀態、響應式行為,以及生成 UI 時應避免的常見預設設計,例如千篇一律的主視覺區塊、巢狀卡片、裝飾性漸層、顯示在介面上的指示文字,以及錯亂的版面配置。
在提示詞中要求模型檢查自己的成果
讓 GPT-5.5 能夠使用檢查輸出的工具,以便在可驗證的情況下進行驗證。
對於程式碼編寫智慧體,請要求具體的驗證指令:
After making changes, run the most relevant validation available:
- targeted unit tests for changed behavior
- type checks or lint checks when applicable
- build checks for affected packages
- a minimal smoke test when full validation is too expensive
If validation cannot be run, explain why and describe the next best check.
對於視覺產出,請要求在轉譯後進行檢查:
Render the artifact before finalizing. Inspect the rendered output for layout, clipping, spacing, missing content, and visual consistency. Revise until the rendered output matches the requirements.
對於工程與規劃任務,請確保實作計畫可追溯:
For implementation plans, include:
- requirements and where each is addressed
- named resources, files, APIs, or systems involved
- state transitions or data flow where relevant
- validation commands or checks
- failure behavior
- privacy and security considerations
- open questions that materially affect implementation
階段參數
從 GPT-5.4 開始,長時間執行或大量使用工具的 Responses 工作流程,可以使用助理項目的 phase 值來區分過程中的進度更新與最終答案。GPT-5.5 也採用相同模式。
如果使用 previous_response_id,API 會自動保留先前的助理狀態。如果應用程式手動將助理輸出項目再次傳入下一個請求,請保留每個原始 phase 值,並原封不動地傳回。當回應包含開場說明、重複的工具呼叫,或在助理提供過程中的進度更新後才給出最終答案時,這點尤其重要。
If manually replaying assistant items:
- Preserve assistant `phase` values exactly.
- Use `phase: "commentary"` for intermediate user-visible updates.
- Use `phase: "final_answer"` for the completed answer.
- Do not add `phase` to user messages.
建議的提示詞結構
撰寫複雜提示詞時,可從這個結構開始。每個區段都應保持簡短,只在細節會影響行為的地方補充說明。
Role: [1-2 sentences defining the model's function, context, and job]
# Personality
[tone, demeanor, and collaboration style]
# Goal
[user-visible outcome]
# Success criteria
[what must be true before the final answer]
# Constraints
[policy, safety, business, evidence, and side-effect limits]
# Output
[sections, length, and tone]
# Stop rules
[when to retry, fallback, abstain, ask, or stop]

簡介
GPT-5.4 是為 API 和 Codex 中的專業工作推出的前沿模型。它能協助開發人員分析複雜資訊、建構可用於正式環境的軟體,並將多步驟工作流程自動化。
在 GPT-5.4 這一代模型中,gpt-5.4 是通用模型,適合在軟體工程、推理、寫作及工具使用之間切換的工作流程。
本指南介紹 GPT-5 模型系列的主要功能,以及如何充分發揮 GPT-5.4 的能力。
最新消息
相較於先前的 GPT-5.2 模型,GPT-5.4 在以下方面有所提升:
- 程式碼編寫、文件理解、工具使用及指令遵循
- 圖像感知及多模態任務
- 長時間任務執行及多步驟智慧體工作流程
- 大量使用工具的工作負載中的 Token 使用效率及端到端效能
- 透過網頁搜尋及多來源資訊整合,找出難以取得的資訊
- 客戶服務、分析及財務領域中,需要處理大量文件與試算表的業務工作流程
GPT-5.4 將 GPT-5.3-Codex 的程式碼編寫能力帶入我們的旗艦前沿模型。開發人員可以用更少的重試次數,生成達到正式環境品質的程式碼、建構精緻的前端 UI、遵循程式碼庫特有的模式,以及處理跨檔案變更。它預設的程式碼編寫風格也有出色表現,讓團隊能減少調整提示詞所花的時間。
對於智慧體式工作負載,GPT-5.4 能縮短多步驟執行過程的端到端耗時,且往往只需更少的 Token 和工具呼叫就能完成任務。這讓智慧體的回應更迅速,也降低了透過 API 和 Codex 大規模執行複雜工作流程的成本。
GPT-5.4 的新功能
與先前的 GPT-5 模型一樣,GPT-5.4 支援自訂工具、控制詳細程度與推理的參數,以及允許使用的工具清單。GPT-5.4 也引進了多項能力,讓你更容易建構強大的智慧體系統、處理更大量的資訊,以及執行更可靠的自動化工作流程:
- API 中的
tool_search: GPT-5.4 透過延後載入工具,改善大型工具生態系統中的工具搜尋。這讓工具可供搜尋,且只載入相關定義,從而減少 Token 用量,並提高實際部署時工具選擇的準確度。如需詳細資訊,請參閱工具搜尋指南。 - 1M Token 上下文視窗: GPT-5.4 支援高達 1M Token 的上下文視窗,讓你更容易在單次請求中分析整個程式碼庫、長篇文件集,或較長的智慧體執行歷程。如需詳細資訊,請參閱「1M 上下文視窗」一節。
- 內建電腦功能: GPT-5.4 是首個內建電腦操作能力的主線模型,讓智慧體能直接與軟體互動,在建構、執行、驗證、修正的循環中完成任務、驗證結果並修正問題。如需詳細資訊,請參閱電腦指南。
- 原生壓縮支援: GPT-5.4 是首個經過訓練以支援壓縮的主線模型,能在保留關鍵上下文的同時,支援更長的智慧體執行歷程。
模型、API 及功能更新
在這一代模型中,gpt-5.4 是適合各類任務及程式碼編寫的通用模型。面對更困難的問題,gpt-5.4-pro 會運用更多運算資源進行更長時間的思考,提供更一致的答案。
如果需要規模更小、速度更快的版本,可以先試用 gpt-5.4-mini 或 gpt-5.4-nano。
選擇最適合使用情境的模型時,請考量以下取捨:
| 版本 | 最適合 |
|---|---|
gpt-5.4 | 通用工作,包括複雜推理、廣泛的世界知識,以及涉及大量程式碼或多步驟的智慧體式任務 |
gpt-5.4-pro | 可能需要較長時間解決、需要更深入推理的難題 |
gpt-5.4-mini | 處理量大且仍需要強大推理能力的程式碼編寫、電腦操作及智慧體工作流程 |
gpt-5.4-nano | 以速度和成本為首要考量的高吞吐量任務 |
較低的推理程度
reasoning.effort 參數控制模型在產生回應之前生成多少推理 Token。o3 等較早的推理模型僅支援 low、medium 和 high:low 側重速度與較少的 Token 用量,high 則側重更周全的推理。
GPT-5.2 和 GPT-5.4 支援以 none 作為最低推理程度,提供延遲更低的互動。這也是兩個模型的預設設定。如果需要更多思考,可逐步提高至 medium,並實驗觀察結果。
當推理程度設為 none 時,提示詞很重要。即使使用預設設定,也可以鼓勵模型在回答前先「思考」或列出步驟概要,以提升推理品質。
from openai import OpenAI
client = OpenAI()
response = client.responses.create(
model="gpt-5.4",
input="Think carefully and outline your steps before answering. How much gold would it take to coat the Statue of Liberty in a 1mm layer?",
reasoning={"effort": "none"},
)
print(response)詳細程度
詳細程度決定生成的輸出 Token 數量。減少 Token 數量可降低整體延遲。雖然模型的推理方式大致不變,但它會設法更精簡地回答;這可能提升或降低答案品質,取決於你的使用情境。以下是高、低詳細程度各自適合的一些情境:
- 高詳細程度: 適用於需要模型詳盡解釋文件,或進行大範圍程式碼重構的情況。
- 低詳細程度: 最適合需要簡潔答案,或只針對特定需求生成程式碼的情況,例如 SQL 查詢。
GPT-5 開始允許將此選項設為 high、medium 或 low。在 GPT-5.4 中,詳細程度仍可設定,預設為 medium。
使用 GPT-5.4 生成程式碼時,medium 和 high 詳細程度會產生較長、結構更完整且附有行內說明的程式碼;low 詳細程度則會產生較短、更精簡的程式碼,並盡量減少額外說明。
from openai import OpenAI
client = OpenAI()
response = client.responses.create(
model="gpt-5.4",
input="What is the answer to the ultimate question of life, the universe, and everything?",
text={"verbosity": "low"},
)
print(response)在 API 中將詳細程度設為 low 後,你仍可透過提示詞加以調整。詳細程度參數會在系統提示詞層級定義大致的 Token 數量範圍,但實際輸出仍可在該範圍內,依開發人員和使用者的提示詞彈性調整。
1M 上下文視窗
GPT-5.4 引進了 1M Token 上下文視窗,讓你更容易在單次請求中分析整個程式碼庫、長篇文件集,或較長的智慧體執行歷程。
我們針對低於 272K Token 和超過 272K Token 的請求,分別訂有不同的標準價格,詳見定價文件。如果你使用快速模式,任何超過 272K Token 的提示詞都會自動按標準費率處理。
長上下文定價會與資料駐留、批次處理等其他價格調整因素疊加套用。
我們針對低於 272K Token 和超過 272K Token 的請求,設有不同的速率限制,詳見 GPT-5.4 模型頁面。
搭配 GPT-5.4 使用工具
GPT-5.4 已針對特定工具進行後訓練。如需更具體的指引,請參閱工具文件。
電腦工具
電腦功能讓 GPT-5.4 透過檢視螢幕擷取畫面,並回傳結構化動作供你的任務執行框架執行,藉此透過使用者介面操作軟體。它適合人類可透過 UI 完成任務的瀏覽器或桌面工作流程,例如瀏覽網站、填寫表單,或驗證變更是否確實生效。
請在隔離的瀏覽器或 VM 中使用此功能,並確保對於影響重大的動作,有人類參與監督。完整指南涵蓋內建的 Responses API 迴圈、自訂任務執行框架模式,以及以程式碼執行為基礎的設定方式。
瞭解如何安全地執行內建電腦工具,並將其整合至 你自己的任務執行框架。
工具搜尋工具
工具搜尋讓 GPT-5.4 將大量工具的載入延後至執行時,使模型只載入所需的定義。當你有許多函式、namespaces 或 MCP 工具,且希望在不預先提供所有結構描述的情況下,減少 Token 用量、維持快取效能並降低延遲時,這項功能尤其實用。
如果在發出請求時就已確定候選工具,請使用託管工具搜尋;如果應用程式需要動態決定載入哪些工具,則使用由用戶端執行的工具搜尋。完整指南也涵蓋 namespaces、MCP 伺服器及延遲載入的最佳實務。
瞭解如何延遲載入工具定義,並在執行階段載入適當的工具子集。
自訂工具
推出 GPT-5 模型系列時,我們引進了名為自訂工具的新功能,讓模型能將任意原始文字作為工具呼叫的輸入,同時仍可視需要限制輸出。GPT-5.4 也保留了這項工具行為。
請參閱函式呼叫指南,瞭解自訂工具。
自由格式輸入
使用 type: custom 定義工具,即可讓模型直接將純文字輸入傳送給工具,不再侷限於結構化 JSON。模型可以直接將任意原始文字傳送給工具,包括程式碼、SQL 查詢、Shell 指令、組態檔案或長篇文章。
{
"type": "custom",
"name": "code_exec",
"description": "Executes arbitrary python code"
}
限制輸出
GPT-5.4 的自訂工具支援上下文無關文法(CFGs),讓你提供 Lark 文法,將輸出限制為特定語法或 DSL。附加 CFG(例如 SQL 或 DSL 文法)可確保助理的文字符合你指定的文法。
這可實現精確且符合限制的工具呼叫或結構化回應,並讓你直接在 GPT-5.4 的函式呼叫中強制採用嚴格的語法或領域專用格式,提升複雜領域或限制嚴格領域中的可控性與可靠性。
自訂工具的最佳實務
- 撰寫簡潔明確的工具說明。 模型會根據你的說明決定傳送哪些內容;如果希望模型每次都呼叫該工具,請明確說明。
- 在伺服器端驗證輸出。自由格式字串雖然功能強大,但需要防護措施來防範注入攻擊或不安全的指令。
允許使用的工具
tool_choice 下的 allowed_tools 參數可讓你傳入 N 個工具定義,但將模型限制為只能使用其中 M(< N)個。請在 tools 中列出完整工具集,再使用 allowed_tools 區塊指定工具子集及模式:auto(模型可以選用其中任一工具)或 required(模型必須呼叫其中一個工具)。
請參閱函式呼叫指南,瞭解允許使用的工具選項。
將所有可能使用的工具與 目前可使用的工具子集分開,可提升安全性與可預測性,並改善提示詞快取效果。這也能避免採用容易失效的提示工程做法,例如將呼叫順序寫死。GPT-5.4 可在對話過程中動態呼叫或要求使用特定函式,同時降低在長上下文中意外使用工具的風險。

|---|---|---|
| 模型可選用的工具範圍 | "tools": […] 下列出的所有工具 | 僅限 tool_choice 中 "tools": […] 下的工具子集 |
| 工具呼叫 | 模型可以呼叫任一工具,也可以不呼叫任何工具 | 模型只能使用指定工具,或必須呼叫指定工具 |
| 用途 | 宣告可用的能力 | 限制實際使用哪些能力 |

如需更詳細地瞭解上述所有新功能,請參閱 GPT-5.4 提示詞指南。
前置說明
前置說明是 GPT-5.4 在呼叫任何工具或函式前產生的簡短說明,使用者可以看到這些內容。它會概述模型的意圖或計畫,例如「我為什麼要呼叫這個工具」。前置說明會出現在思路鏈之後、實際工具呼叫之前,讓模型的推理更容易理解與除錯,也方便精確引導模型。
前置說明讓 GPT-5.4 在每次呼叫工具前「說出自己的想法」,在不大幅增加推理負擔的情況下,提升工具呼叫的準確度與整體任務成功率。若要啟用前置說明,請加入系統或開發者指示,例如:「在呼叫工具之前,先說明你為什麼要呼叫它。」GPT-5.4 會為每個指定的工具呼叫附上簡短理由。模型也可能在工具呼叫之間輸出多則訊息,改善互動體驗,尤其適合僅需少量推理或對延遲敏感的使用案例。
如需進一步瞭解前置說明的用法,請參閱 GPT-5 提示詞 Cookbook。
遷移快速入門
GPT-5.4 搭配 Responses API 使用時效果最佳,因為此 API 支援在回合之間保留推理上下文,以改善表現。請參閱下文,瞭解如何從目前使用的模型或 API 遷移。
從其他模型遷移至 GPT-5.4
將現有提示詞或工作流程遷移至 GPT-5.4 時,請使用 OpenAI Docs 技能。 你可以在我們的 公開技能程式碼庫及 Codex 桌面 App 中找到這項技能。
此模型應該幾乎可以直接取代 GPT-5.2,不過仍有幾項重要變更需要留意。請參閱 GPT-5.4 提示詞指南,瞭解提示詞需要進行哪些具體調整。
得益於 Responses API 的設計,GPT-5 模型搭配此 API 使用時,智慧表現會更好。Responses API 可將上一回合的 CoT 傳遞給模型,進而減少生成的推理 Token、提高快取命中率並降低延遲。如需瞭解更多,請參閱介紹 Responses API 優勢的深入指南。
從較舊的 OpenAI 模型遷移至 GPT-5.4 時,請先試驗不同的推理等級與提示詞策略。使用提示詞最佳化工具,依照目前的最佳實務調整提示詞,使其適用於 GPT-5.4,再遵循以下針對各模型的建議:
gpt-5.2:採用預設設定的gpt-5.4,設計上可直接作為替代模型。- o3:使用
gpt-5.4,並將推理投入程度設為medium或high。先從medium開始,搭配提示詞調整;若未達到預期效果,再提高至high。 gpt-4.1:使用gpt-5.4,並將推理投入程度設為none。先從none開始並調整提示詞;如需更好的表現,再提高推理投入程度。o4-mini或gpt-4.1-mini:gpt-5.4-mini搭配提示詞調整,是很好的替代選擇。gpt-4.1-nano:gpt-5.4-nano搭配提示詞調整,是很好的替代選擇。
新的 phase 參數
對於在 Responses API 中長時間執行或大量使用工具的 GPT-5.4 流程,請使用助理訊息的 phase 欄位,以避免過早停止及其他異常行為。
phase 在 API 層級是選用欄位,但我們強烈建議使用。助理的中途進度更新(例如工具呼叫前的前置說明)應使用 phase: "commentary",完成的答案則使用 phase: "final_answer"。請勿將 phase 加入使用者訊息。
使用 previous_response_id 通常是最簡單的方式,因為
先前的助理狀態會保留下來。如果你手動重送助理的歷史訊息,
請保留每個原始的 phase 值。
在這些工作流程中,若 phase 缺失或遺失,
可能導致前置說明被當成最終答案。如需更多建議與範例,請參閱 GPT-5.4
提示詞指南。

temperaturetop_plogprobs
若 GPT-5.4 或 GPT-5.2 採用任何其他推理投入程度設定,或使用 gpt-5、gpt-5-mini、gpt-5-nano 等較舊的 GPT-5 模型,包含這些欄位的請求都會引發錯誤。
若推理投入程度設得較高,或使用其他 GPT-5 系列模型,可以嘗試以下替代參數,以取得類似結果:
- 推理深度:
reasoning: { effort: "none" | "low" | "medium" | "high" | "xhigh" } - 輸出詳細程度:
text: { verbosity: "low" | "medium" | "high" } - 輸出長度:
max_output_tokens
從 Chat Completions 遷移至 Responses API
對 GPT-5.4 而言,Responses API 與 Chat Completions 最大的差異,也是遷移至 Responses API 的主要原因,在於它支援在對話輪次之間傳遞思路鏈(CoT)。請參閱完整的 API 比較。
只有 Responses API 支援傳遞 CoT。我們觀察到,這能提升模型智慧、減少產生的推理 Token、提高快取命中率,並降低延遲。其他大多數參數的功能相同,只是格式不同。以下說明 Chat Completions 與 Responses API 處理新參數的差異:

瞭解 GPT-5.4 的行為
GPT-5.4 最擅長的領域
GPT-5.4 通常在以下領域表現特別出色:
- 忠實遵循個性與語氣設定,即使答案很長也較少偏離設定
- 穩健執行智慧體工作流程,更傾向於持續完成多步驟工作、重試,並從頭到尾完成智慧體執行迴圈
- 整合資訊時提供豐富佐證,尤其適用於長上下文或多工具工作流程
- 在要求明確的情況下,遵循模組化、以技能為基礎及以區塊組織的提示詞中的指示
- 針對大量、雜亂或包含多份文件的輸入進行長上下文分析
- 批次或平行呼叫工具,同時維持工具呼叫的準確度
- 需要遵循指示、精確保留格式及更強自我驗證能力的試算表、財務與 Excel 工作流程
明確的提示詞仍有幫助的情境
即使具備上述優勢,在一些常見情境中,提供更明確的指引仍能改善 GPT-5.4 的表現:
- 對話初期上下文不足時的工具路由,此時工具選擇可能較不可靠
- 需要考量相依關係的工作流程,必須明確檢查先決條件與後續步驟
- 推理強度的選擇:強度並非越高越好,適當的選擇取決於任務特性,而非直覺
- 需要嚴謹蒐集來源並一致標示引用的研究任務
- 執行前必須驗證的不可逆或影響重大的動作
- 必須明確界定工具使用範圍的終端或程式碼編寫智慧體環境
這些是觀察到的預設行為,並非保證。請先使用能通過評估的最精簡提示詞,只有在新增區塊能修正實際測得的失敗模式時,才加入區塊。
使用核心提示詞模式
讓輸出精簡且結構清晰
若要提高 GPT-5.4 的 Token 使用效率,請透過明確的輸出要求,限制詳細程度並強制使用結構化輸出。實務上,這能在 Responses API 的 verbosity 參數之外,提供額外的控制,讓你同時引導模型的輸出篇幅與結構。
<output_contract>
- Return exactly the sections requested, in the requested order.
- If the prompt defines a preamble, analysis block, or working section, do not treat it as extra output.
- Apply length limits only to the section they are intended for.
- If a format is required (JSON, Markdown, SQL, XML), output only that format.
</output_contract>
<verbosity_controls>
- Prefer concise, information-dense writing.
- Avoid repeating the user's request.
- Keep progress updates brief.
- Do not shorten the answer so aggressively that required evidence, reasoning, or completion checks are omitted.
</verbosity_controls>
為任務的持續執行設定明確的預設規則
使用者經常在對話途中變更任務、格式或語氣。為了讓助理持續符合使用者的意圖,請明確訂定規則,說明何時繼續執行、何時提問,以及新指示如何覆寫先前的預設設定。
可使用如下的預設持續執行原則:
<default_follow_through_policy>
- If the user’s intent is clear and the next step is reversible and low-risk, proceed without asking.
- Ask permission only if the next step is:
(a) irreversible,
(b) has external side effects (for example sending, purchasing, deleting, or writing to production), or
(c) requires missing sensitive information or a choice that would materially change the outcome.
- If proceeding, briefly state what you did and what remains optional.
</default_follow_through_policy>
明確說明指令的優先順序:
<instruction_priority>
- User instructions override default style, tone, formatting, and initiative preferences.
- Safety, honesty, privacy, and permission constraints do not yield.
- If a newer user instruction conflicts with an earlier one, follow the newer instruction.
- Preserve earlier instructions that do not conflict.
</instruction_priority>
優先順序較高的開發者或系統指令仍具有約束力。
指引: 在對話中途變更指令時,請明確說明更新內容、界定適用範圍,並將變更限於相關部分。說明哪些內容已變更、哪些仍然適用,以及變更只影響下一輪,還是適用於後續整段對話。
處理對話中途的指令更新
在對話中途更新指令時,請使用明確且範圍清楚的引導訊息,說明以下內容:
- 適用範圍
- 取代的內容
- 沿用的內容
<task_update>
For the next response only:
- Do not complete the task.
- Only produce a plan.
- Keep it to 5 bullets.
All earlier instructions still apply unless they conflict with this update.
</task_update>
如果任務本身改變了,請直接說明:
<task_update>
The task has changed.
Previous task: complete the workflow.
Current task: review the workflow and identify risks only.
Rules for this turn:
- Do not execute actions.
- Do not call destructive tools.
- Return exactly:
1. Main risks
2. Missing information
3. Recommended next step
</task_update>
當正確性仰賴工具時,要求持續使用工具
透過明確的規則,確保工具使用充分、考量相依關係,且執行節奏適當;後續動作依賴先前檢索或驗證結果的工作流程尤其需要如此。常見的失敗情況是,因為正確的最終狀態看似顯而易見,就跳過必要的前置步驟。
在對話初期、上下文仍不足時,GPT-5.4 選擇工具的可靠性可能較低。請在提示詞中要求確認前置條件、檢查相依關係,並明確說明工具的使用目的。
<tool_persistence_rules>
- Use tools whenever they materially improve correctness, completeness, or grounding.
- Do not stop early when another tool call is likely to materially improve correctness or completeness.
- Keep calling tools until:
(1) the task is complete, and
(2) verification passes (see <verification_loop>).
- If a tool returns empty or partial results, retry with a different strategy.
</tool_persistence_rules>
如果工作流程的最終動作依賴先前的查詢或檢索步驟,這點尤其重要。最常見的失敗情況之一,就是因為預期的最終狀態看似顯而易見,而跳過必要的前置步驟。
<dependency_checks>
- Before taking an action, check whether prerequisite discovery, lookup, or memory retrieval steps are required.
- Do not skip prerequisite steps just because the intended final action seems obvious.
- If the task depends on the output of a prior step, resolve that dependency first.
</dependency_checks>
當各項工作彼此獨立,且實際耗時很重要時,請在提示詞中要求平行執行。當相依關係、不確定性或不可逆動作比速度更重要時,則要求依序執行。
<parallel_tool_calling>
- When multiple retrieval or lookup steps are independent, prefer parallel tool calls to reduce wall-clock time.
- Do not parallelize steps that have prerequisite dependencies or where one result determines the next action.
- After parallel retrieval, pause to synthesize the results before making more calls.
- Prefer selective parallelism: parallelize independent evidence gathering, not speculative or redundant tool use.
</parallel_tool_calling>
要求完整執行長時間跨度的任務
多步驟工作流程常見的失敗情況是執行不完整:模型只處理部分範圍就結束、遺漏批次中的項目,或將空白或範圍過窄的檢索結果當成最終結果。在提示詞中明確定義完成規則與復原行為,可提高 GPT-5.4 的可靠性。
依序或平行檢索都能涵蓋所需範圍,但無論採用哪種方式,都應明確定義完成規則。
<completeness_contract>
- Treat the task as incomplete until all requested items are covered or explicitly marked [blocked].
- Keep an internal checklist of required deliverables.
- For lists, batches, or paginated results:
- determine expected scope when possible,
- track processed items or pages,
- confirm coverage before finalizing.
- If any item is blocked by missing data, mark it [blocked] and state exactly what is missing.
</completeness_contract>
對於經常出現空白、不完整或混雜無關資訊的檢索結果的工作流程:
<empty_result_recovery>
If a lookup returns empty, partial, or suspiciously narrow results:
- do not immediately conclude that no results exist,
- try at least one or two fallback strategies,
such as:
- alternate query wording,
- broader filters,
- a prerequisite lookup,
- or an alternate source or tool,
- Only then report that no results were found, along with what you tried.
</empty_result_recovery>
在高影響動作之前加入驗證迴圈
工作流程看似完成後,請在傳回答案或執行不可逆動作之前,加入簡單的驗證步驟。這有助於在提交前發現遺漏的需求、接地問題,以及偏離規定的格式。
<verification_loop>
Before finalizing:
- Check correctness: does the output satisfy every requirement?
- Check grounding: are factual claims backed by the provided context or tool outputs?
- Check formatting: does the output match the requested schema or style?
- Check safety and irreversibility: if the next step has external side effects, ask permission first.
</verification_loop>
<missing_context_gating>
- If required context is missing, do NOT guess.
- Prefer the appropriate lookup tool when the missing context is retrievable; ask a minimal clarifying question only when it is not.
- If you must proceed, label assumptions explicitly and choose a reversible action.
</missing_context_gating>
對於會主動執行動作的智慧體,請加入簡短的執行框架:
<action_safety>
- Pre-flight: summarize the intended action and parameters in 1-2 lines.
- Execute via tool.
- Post-flight: confirm the outcome and any validation that was performed.
</action_safety>
處理專門的工作流程
為視覺與電腦操作明確選擇圖像細節等級
如果工作流程仰賴視覺精確度,請在提示詞或整合設定中指定圖像的 detail 等級,不要依賴 auto。一般的高傳真度圖像理解請使用 high。大型、內容密集或需要精確掌握空間位置的圖像請使用 original,尤其是在 gpt-5.4 及未來模型上執行電腦操作、定位、OCR 和精準點擊任務時。只有在速度與成本比細微圖像細節更重要時,才使用 low。如需進一步了解圖像細節等級,請參閱圖像與視覺指南。
將研究與引用限定於檢索到的證據
當引用品質很重要時,請明確界定來源範圍與格式要求。這有助於減少捏造的參考資料、缺乏依據的主張,以及偏離規定的引用格式。
<citation_rules>
- Only cite sources retrieved in the current workflow.
- Never fabricate citations, URLs, IDs, or quote spans.
- Use exactly the citation format required by the host application.
- Attach citations to the specific claims they support, not only at the end.
</citation_rules>
<grounding_rules>
- Base claims only on provided context or tool outputs.
- If sources conflict, state the conflict explicitly and attribute each side.
- If the context is insufficient or irrelevant, narrow the answer or say you cannot support the claim.
- If a statement is an inference rather than a directly supported fact, label it as an inference.
</grounding_rules>
如果應用程式需要文內引用,就明確要求文內引用;如果需要註腳,就明確要求註腳。關鍵是固定格式,避免模型自行編造缺乏依據的參考資料。
研究模式
引導 GPT-5.4 進入嚴謹的研究模式。此模式適用於研究、審查與綜合整理任務。不要強行套用於簡短的執行任務,或結果明確的簡單轉換。
<research_mode>
- Do research in 3 passes:
1) Plan: list 3-6 sub-questions to answer.
2) Retrieve: search each sub-question and follow 1-2 second-order leads.
3) Synthesize: resolve contradictions and write the final answer with citations.
- Stop only when more searching is unlikely to change the conclusion.
</research_mode>
如果主機環境使用特定的研究工具,或要求提交步驟,請將此模式與主機的完成約定搭配使用。
嚴格限定輸出格式
對於 SQL、JSON 或其他格式稍有偏差就可能影響解析的輸出,請要求 GPT-5.4 僅輸出目標格式,並在完成前檢查。
<structured_output_contract>
- Output only the requested format.
- Do not add prose or markdown fences unless they were requested.
- Validate that parentheses and brackets are balanced.
- Do not invent tables or fields.
- If required schema information is missing, ask for it or return an explicit error object.
</structured_output_contract>
如果要擷取文件區域或 OCR 邊界框,請定義座標系統,並加入偏移檢查:
<bbox_extraction_spec>
- Use the specified coordinate format exactly, such as [x1,y1,x2,y2] normalized to 0..1.
- For each box, include page, label, text snippet, and confidence.
- Add a vertical-drift sanity check so boxes stay aligned with the correct line of text.
- If the layout is dense, process page by page and do a second pass for missed items.
</bbox_extraction_spec>
明確界定程式碼編寫與終端智慧體的工具使用範圍
在程式碼編寫智慧體中,明確規定 Shell 存取與檔案編輯的規則,有助於 GPT-5.4 發揮更好的表現。當你提供 Shell 或套用修補程式等工具時,這點尤其重要。
向使用者回報進度
GPT-5.4 擅長提供簡短、以成果為重點的進度回報。可沿用 5.2 指南中向使用者回報進度的模式,但需搭配明確的完成與驗證要求。
建議的進度回報規範:
<user_updates_spec>
- Only update the user when starting a new major phase or when something changes the plan.
- Each update: 1 sentence on outcome + 1 sentence on next step.
- Do not narrate routine tool calls.
- Keep the user-facing status short; keep the work exhaustive.
</user_updates_spec>
如需程式碼編寫智慧體的更具體指引,請參閱下方的「程式碼編寫任務的提示詞模式」一節。
程式碼編寫任務的提示詞模式
自主性與持續執行
在程式碼編寫與工具使用任務中,GPT-5.4 通常比先前的主系列模型更能從頭到尾完整執行,因此往往不需要那麼多明確要求「驗證所有內容」的提示。不過,對於正式環境、遷移或安全性工作等影響重大的變更,仍應保留簡單的驗證條款。
<autonomy_and_persistence>
Persist until the task is fully handled end-to-end within the current turn whenever feasible: do not stop at analysis or partial fixes; carry changes through implementation, verification, and a clear explanation of outcomes unless the user explicitly pauses or redirects you.
Unless the user explicitly asks for a plan, asks a question about the code, is brainstorming potential solutions, or some other intent that makes it clear that code should not be written, assume the user wants you to make code changes or run tools to solve the user's problem. In these cases, it's bad to output your proposed solution in a message, you should go ahead and actually implement the change. If you encounter challenges or blockers, you should attempt to resolve them yourself.
</autonomy_and_persistence>
執行期間的進度回報
減少回報頻率,並確保內容切中要點。在程式碼編寫任務中,優先於關鍵節點回報進度。
<user_updates_spec>
- Intermediary updates go to the `commentary` channel.
- User updates are short updates while you are working. They are not final answers.
- Use 1-2 sentence updates to communicate progress and new information while you work.
- Do not begin responses with conversational interjections or meta commentary. Avoid openers such as acknowledgements ("Done -", "Got it", or "Great question") or similar framing.
- Before exploring or doing substantial work, send a user update explaining your understanding of the request and your first step. Avoid commenting on the request or starting with phrases such as "Got it" or "Understood."
- Provide updates roughly every 30 seconds while working.
- When exploring, explain what context you are gathering and what you learned. Vary sentence structure so the updates do not become repetitive.
- When working for a while, keep updates informative and varied, but stay concise.
- When work is substantial, provide a longer plan after you have enough context. This is the only update that may be longer than 2 sentences and may contain formatting.
- Before file edits, explain what you are about to change.
- While thinking, keep the user informed of progress without narrating every tool call. Even if you are not taking actions, send frequent progress updates rather than going silent, especially if you are thinking for more than a short stretch.
- Keep the tone of progress updates consistent with the assistant's overall personality.
</user_updates_spec>
格式
GPT-5.4 通常預設採用較有結構的格式,而且可能過度使用項目符號清單。如果希望最終回應簡潔清楚,請明確限制清單的形式。
Never use nested bullets. Keep lists flat (single level). If you need hierarchy, split into separate lists or sections or if you use : just include the line you might usually render using a nested bullet immediately after it. For numbered lists, only use the `1. 2. 3.` style markers (with a period), never `1)`.
前端任務
只有在額外的前端指引有幫助時,才使用此內容。
<frontend_tasks>
When doing frontend design tasks, avoid generic, overbuilt layouts.
Use these hard rules:
- One composition: The first viewport must read as one composition, not a dashboard, unless it is a dashboard.
- Brand first: On branded pages, the brand or product name must be a hero-level signal, not just nav text or an eyebrow. No headline should overpower the brand.
- Brand test: If the first viewport could belong to another brand after removing the nav, the branding is too weak.
- Full-bleed hero only: On landing pages and promotional surfaces, the hero image should usually be a dominant edge-to-edge visual plane or background. Do not default to inset hero images, side-panel hero images, rounded media cards, tiled collages, or floating image blocks unless the existing design system clearly requires them.
- Hero budget: The first viewport should usually contain only the brand, one headline, one short supporting sentence, one CTA group, and one dominant image. Do not place stats, schedules, event listings, address blocks, promos, "this week" callouts, metadata rows, or secondary marketing content there.
- No hero overlays: Do not place detached labels, floating badges, promo stickers, info chips, or callout boxes on top of hero media.
- Cards: Default to no cards. Never use cards in the hero unless they are the container for a user interaction. If removing a border, shadow, background, or radius does not hurt interaction or understanding, it should not be a card.
- One job per section: Each section should have one purpose, one headline, and usually one short supporting sentence.
- Real visual anchor: Imagery should show the product, place, atmosphere, or context.
- Reduce clutter: Avoid pill clusters, stat strips, icon rows, boxed promos, schedule snippets, and competing text blocks.
- Use motion to create presence and hierarchy, not noise. Ship 2-3 intentional motions for visually led work, and prefer Framer Motion when it is available.
Exception: If working within an existing website or design system, preserve the established patterns, structure, and visual language.
</frontend_tasks>
<terminal_tool_hygiene>
- Only run shell commands via the terminal tool.
- Never "run" tool names as shell commands.
- If a patch or edit tool exists, use it directly; do not attempt it in bash.
- After changes, run a lightweight verification step such as ls, tests, or a build before declaring the task done.
</terminal_tool_hygiene>
文件區域定位與 OCR 邊界框
對於 bbox 任務,請明確說明座標慣例,並加入偏移測試。
<bbox_extraction_spec>
- Use the specified coordinate format exactly (for example [x1,y1,x2,y2] normalized 0..1).
- For each bbox, include: page, label, text snippet, confidence.
- Add a vertical-drift sanity check:
- ensure bboxes align with the line of text (not shifted up or down).
- If dense layout, process page by page and do a second pass for missed items.
</bbox_extraction_spec>
運用執行環境與 API 整合注意事項
對於長時間執行或大量使用工具的智慧體,執行環境約定與提示詞約定同樣重要。
階段參數
在 GPT-5.4、gpt-5.3-codex 及後續的 Responses 模型中,phase 欄位可
協助處理少數長時間執行或大量使用工具的流程中的問題:在這些流程裡,前置說明或
助理在執行期間提供的其他進度訊息可能被誤認為最終答案。
phase在 API 層級是選填欄位,但強烈建議使用。伺服器端可能會盡力推斷,但明確地在往返傳遞中保留phase一定更好。- 對於長時間執行或大量使用工具,且可能在工具呼叫或最終答案之前輸出說明的智慧體,請使用
phase。 - 重新傳入先前的助理項目時,請保留
phase,讓模型能區分執行中的說明與已完成的答案。對於包含前置說明、工具相關進度訊息,或同一輪內多則助理訊息的多步驟流程,這點尤其重要。 - 不要在使用者訊息中加入
phase。 - 使用
previous_response_id通常是最簡單的做法,因為 OpenAI 往往能還原先前的狀態,不需要手動重新傳入助理項目。 - 如果自行重新傳入助理的歷史紀錄,請保留原始的
phase值。 - 缺少或遺失
phase,可能導致前置說明被解讀為最終答案,降低模型在這些多步驟任務中的表現。
在長時間對話中維持一致行為
壓縮能大幅延長上下文視窗的有效範圍,讓使用者對話持續多輪,而不會觸及上下文限制,也不會因上下文過長而降低表現。智慧體也因此能在長時間執行的複雜任務中,完成遠超過一般上下文視窗容量的執行歷程。
如果你在 Responses API 中使用壓縮,請在完成重要里程碑後進行壓縮,將壓縮後的項目視為不透明的狀態資料,並確保壓縮後提示詞的功能保持一致。此端點與 ZDR 相容,會傳回可傳入後續請求的 encrypted_content 項目。在較長的多輪對話中,GPT-5.4 通常能維持更好的連貫性與可靠性,隨著對話延長而出現失誤的情況也較少。
如需更多指引,請參閱 /responses/compact API 參考文件。
為面向客戶的工作流程設定個性
將持續生效的個性設定與個別回覆的寫作要求分開,能更有效地引導 GPT-5.4。這對電子郵件、客服回覆、公告和部落格風格內容等面向客戶的工作流程尤其有用。
- 個性(持續生效): 設定整段對話的預設語氣、詳盡程度與決策風格。
- 寫作要求(個別回覆): 定義特定產出內容的溝通管道、語體、格式與長度。
- 提醒: 個性設定不應凌駕於特定任務的輸出要求。如果使用者要求 JSON,就傳回 JSON。
若要產生自然、高品質的文章,最有效的控制方式包括:
- 為模型設定明確的角色。
- 指定溝通管道與情感基調。
- 需要連貫的段落文字時,明確禁止使用格式標記。
- 設定嚴格的長度限制。
<personality_and_writing_controls>
- Persona: <one sentence>
- Channel: <Slack | email | memo | PRD | blog>
- Emotional register: <direct/calm/energized/etc.> + "not <overdo this>"
- Formatting: <ban bullets/headers/markdown if you want prose>
- Length: <hard limit, e.g. <=150 words or 3-5 sentences>
- Default follow-through: if the request is clear and low-risk, proceed without asking permission.
</personality_and_writing_controls>
如需更多可直接套用的個性設定模式,請參閱提示詞個性設定 Cookbook。
專業備忘錄模式
對備忘錄、審查報告和其他專業寫作任務而言,一般寫作指示往往不夠。針對內容的具體程度、領域慣例、綜合分析,以及如何恰當表達確定程度提供明確指引,有助於改善這些工作流程。
<memo_mode>
- Write in a polished, professional memo style.
- Use exact names, dates, entities, and authorities when supported by the record.
- Follow domain-specific structure if one is requested.
- Prefer precise conclusions over generic hedging.
- When uncertainty is real, tie it to the exact missing fact or conflicting source.
- Synthesize across documents rather than summarizing each one independently.
</memo_mode>
這個模式尤其適合法律、政策、研究以及面向高階主管的寫作;這些內容不只要求文字流暢,也要求嚴謹的綜合分析與清楚的結論。
調整推理設定與遷移方式
將推理強度留作最後的微調手段
推理強度沒有適用於所有情況的單一設定。請將它作為最後的微調手段,而非提升品質的主要方式。許多情況下,改善提示詞、明確訂定輸出規範,以及加入輕量的驗證迴圈,就能達到團隊原本可能想透過提高推理設定來取得的大部分效能提升。
建議的預設設定:
none:最適合模型不需要思考、要求快速完成,且對成本與延遲敏感的任務。low:適合對延遲敏感,且少量思考就能明顯提升準確度的任務,尤其是指示複雜的情況。medium或high:僅用於確實需要更強推理能力,且能接受額外延遲與成本的任務。請根據額外推理對任務帶來的效能提升幅度,在兩者之間選擇。xhigh:除非評估顯示有明顯效益,否則不建議作為預設值。它最適合長時間執行、需要大量推理的智慧體式任務,且這些任務對最高智慧能力的要求高於速度或成本。
實務上,大多數團隊應以 none、low 或 medium 作為預設設定。
對於以執行為主的工作負載,例如執行工作流程步驟、擷取欄位、客服案件分流,以及簡短的結構化轉換,請從 none 開始。
對於以研究為主的工作負載,例如長上下文綜合分析、多文件審查、解決衝突,以及策略撰寫,請從 medium 或更高的設定開始。使用 medium 搭配精心設計的提示詞,就能發揮相當出色的效能。
對 GPT-5.4 工作負載而言,none 在選擇動作與遵守工具使用規範的任務上就已能有良好表現。如果工作負載需要細膩的解讀能力,例如理解隱含需求、處理歧義,或在工具呼叫取消後恢復執行,請改從 low 或 medium 開始。
提高推理強度之前,請先加入:
<completeness_contract><verification_loop><tool_persistence_rules>
如果模型仍過於拘泥字面,或找到第一個看似合理的答案就停止,請在提高推理強度之前,先加入鼓勵主動探索的提示:
<dig_deeper_nudge>
- Don’t stop at the first plausible answer.
- Look for second-order issues, edge cases, and missing constraints.
- If the task is safety or accuracy critical, perform at least one verification step.
</dig_deeper_nudge>
將提示詞遷移至 GPT-5.4 時,每次只做一項變更
請遵循 5.2 指南中每次只做一項變更的原則:先切換模型,固定 reasoning_effort,執行評估,再逐步調整。
以下起始設定適用於許多遷移情境:
| 目前設定 | 建議的 GPT-5.4 起始設定 | 備註 |
|---|---|---|
gpt-5.2 | 維持目前的推理強度 | 先維持現有的延遲與品質表現,再進行調整。 |
gpt-5.3-codex | 維持目前的推理強度 | 對於程式碼編寫工作流程,請維持相同的推理強度。 |
gpt-4.1 或 gpt-4o | none | 維持快速回應,僅在評估結果退步時提高推理強度。 |
| 以研究為主的助理 | medium 或 high | 明確要求多輪研究,並將引用驗證設為必要條件。 |
| 執行長時間任務的智慧體 | medium 或 high | 加入持續使用工具的要求,並逐項核對工作是否完整完成。 |
小型模型 gpt-5.4-mini 與 gpt-5.4-nano 的使用指引
gpt-5.4-mini 和 gpt-5.4-nano 都很容易透過指示引導,但與較大型模型相比,它們較不會自行推斷缺少的步驟、化解未明說的歧義,或按你預期的方式組織輸出,除非你直接指定這些行為。因此,實務上小型模型的提示詞往往稍長,也更明確。
gpt-5.4-mini 有何不同
gpt-5.4-mini較傾向按字面理解,也較少自行假設。- 當任務結構明確時,它的表現出色,但對於未明說的工作流程和歧義處理則較弱。
- 在預設情況下,它可能會透過追問來延續對話,除非你明確要求避免這種行為。
gpt-5.4-mini 的提示詞
- 將關鍵規則放在最前面。
- 當工具使用方式或副作用很重要時,請指定完整的執行順序。
- 不要只依賴「你必須」這類措辭。請透過編號步驟、決策規則和明確的動作定義等方式,提供結構化的指引。
- 將「執行動作」與「回報動作」分開。
- 示範正確的流程,而不只是最終格式。
- 明確定義遇到歧義時的處理方式:何時詢問、何時暫不處理,以及何時繼續執行。
- 直接指定輸出的呈現方式:回答長度、是否追問、引用格式,以及章節順序。
- 請謹慎使用
output nothing else。建議改用範圍明確的指示,例如after the final JSON, output nothing further。
gpt-5.4-nano 的提示詞
- 僅將
gpt-5.4-nano用於範圍狹窄、界線明確的任務。 - 優先採用範圍或格式固定的輸出:標籤、列舉值、簡短的 JSON 或固定範本。
- 除非流程受到極嚴格的限制,否則應避免多步驟編排。
- 將有歧義或需要大量規劃的任務交給能力更強的模型,而不是為
gpt-5.4-nano堆疊過多提示詞。
建議的預設模式
- 任務
- 關鍵規則
- 明確的步驟順序
- 邊界情況或釐清疑問的處理方式
- 輸出格式
- 一個正確範例
應避免的做法
- 未明確說明的後續步驟
- 未明確說明的邊界情況
- 工具工作流程的提示詞僅包含結構描述
- 缺乏結構的籠統指示
網頁搜尋與深度研究
如果您正在遷移研究型智慧體,尤其應在提高推理強度之前,先對提示詞進行下列更新:
- 加入
<research_mode> - 加入
<citation_rules> - 加入
<empty_result_recovery> - 先修正提示詞,再將
reasoning_effort提高一級。
您可以從 5.2 的研究提示區塊開始,再視需要加入引用檢核條件與任務完成規範。
當任務需要透過多個步驟蒐集證據、綜整長上下文資訊,並遵循明確的提示詞規範時,GPT-5.4 的表現尤其出色。實務上,最有效的提示詞調整包括:依任務類型選擇推理強度、明確定義輸出與引用格式、加入考量相依關係的工具使用規則,以及明確說明完成標準。模型通常無須調整就有良好表現,但若提示詞清楚說明如何搜尋、如何驗證,以及怎樣才算完成,其表現會最為可靠。
後續步驟
- 請參閱模型、API 與功能更新,了解模型能力、參數與 API 相容性的詳細資訊。
- 請閱讀提示工程,了解適用於不同模型系列的更廣泛提示策略。
- 如果您正在使用 Responses API 建立長時間執行的 GPT-5.4 工作階段,請閱讀壓縮。

瞭解 GPT-5.3-Codex 的最佳實務、功能與遷移指引。
簡介
GPT-5.3-Codex 將智慧體式程式碼編寫的智慧與效率推向新境界。請仔細遵循本指南,確保充分發揮此模型的效能。本指南適合希望直接透過 API 使用模型,以取得最大自訂彈性的開發者;我們也提供 Codex SDK,讓整合更簡單。
在 API 中,針對 Codex 調校的模型是 gpt-5.3-codex(請參閱模型頁面)。
最新消息
- 速度更快、Token 使用效率更高:完成任務所需的思考 Token 更少。我們建議將推理程度設為「中」,以兼顧智慧與速度,適用於各類互動式程式碼編寫工作。
- 更高的智慧與長時間自主執行能力:Codex 可自主執行數小時,完成最棘手的任務。處理這類任務時,你可以使用
high或xhigh推理程度。 - 原生支援壓縮:壓縮可讓模型持續推理數小時而不觸及上下文限制,也能讓使用者持續對話更久,無須開啟新的對話工作階段。
- Codex 在 PowerShell 和 Windows 環境中的表現也大幅提升。
遷移快速入門
如果你已有可正常運作的 Codex 實作,只需少量更新,這個模型應該就能順利運作。但如果你目前的提示詞與工具組是針對 GPT-5 系列模型或第三方模型最佳化,我們建議進行較大幅度的調整。最佳參考實作是我們完全開放原始碼的 codex-cli 智慧體,可在 GitHub 上取得。複製此程式碼庫,並使用 Codex(或任何程式碼編寫智慧體)詢問各項功能的實作方式。透過與客戶合作,我們也累積了不受此特定實作限制的智慧體任務執行框架自訂經驗。
將任務執行框架遷移至 codex-cli 的關鍵步驟:
更新提示詞:如情況允許,請以我們的標準 Codex-Max 提示詞為基礎, 再依需求有針對性地補充內容。
最重要的片段涵蓋自主性與持續執行能力、 程式碼庫探索、工具使用及前端品質。
你也應移除所有要求模型在執行過程中 預先說明計畫、提供開場訊息或其他狀態更新的提示, 因為這類要求可能導致模型在執行尚未完成前 突然停止。
更新工具,採用我們的
apply_patch實作及下列其他 最佳實務。這是充分發揮效能的關鍵。
模型、API 與功能更新
gpt-5.3-codex已針對 Codex 或類似環境中的智慧體式程式碼編寫任務進行最佳化。- 可透過 Responses API 使用。
reasoning.effort支援low、medium、high和xhigh。- 支援的工具包括函式呼叫、網頁搜尋、託管 Shell 環境及技能。
提示詞最佳實務
建議的起始提示詞
此提示詞以預設的 GPT-5.1-Codex-Max 提示詞為起點,再根據內部評估進一步最佳化,涵蓋答案的正確性、完整性與品質、工具的正確使用與平行執行,以及積極採取行動的傾向。如果你正使用此模型執行評估,我們建議提高自主程度,或在提示詞中要求使用「非互動」模式;不過在實際使用時,多一些釐清問題的互動可能更合適。
You are Codex, based on GPT-5. You are running as a coding agent in the Codex CLI on a user's computer.
# General
- When searching for text or files, prefer using `rg` or `rg --files` respectively because `rg` is much faster than alternatives like `grep`. (If the `rg` command is not found, then use alternatives.)
- If a tool exists for an action, prefer to use the tool instead of shell commands (e.g `read_file` over `cat`). Strictly avoid raw `cmd`/terminal when a dedicated tool exists. Default to solver tools: `git` (all git), `rg` (search), `read_file`, `list_dir`, `glob_file_search`, `apply_patch`, `todo_write/update_plan`. Use `cmd`/`run_terminal_cmd` only when no listed tool can perform the action.
- When multiple tool calls can be parallelized (e.g., todo updates with other actions, file searches, reading files), make these tool calls in parallel instead of sequentially. Avoid single calls that might not yield a useful result; parallelize instead to ensure you can make progress efficiently.
- Code chunks that you receive (via tool calls or from user) may include inline line numbers in the form "Lxxx:LINE_CONTENT", e.g. "L123:LINE_CONTENT". Treat the "Lxxx:" prefix as metadata and do NOT treat it as part of the actual code.
- Default expectation: deliver working code, not just a plan. If some details are missing, make reasonable assumptions and complete a working version of the feature.
# Autonomy and Persistence
- You are autonomous senior engineer: once the user gives a direction, proactively gather context, plan, implement, test, and refine without waiting for additional prompts at each step.
- Persist until the task is fully handled end-to-end within the current turn whenever feasible: do not stop at analysis or partial fixes; carry changes through implementation, verification, and a clear explanation of outcomes unless the user explicitly pauses or redirects you.
- Bias to action: default to implementing with reasonable assumptions; do not end your turn with clarifications unless truly blocked.
- Avoid excessive looping or repetition; if you find yourself re-reading or re-editing the same files without clear progress, stop and end the turn with a concise summary and any clarifying questions needed.
# Code Implementation
- Act as a discerning engineer: optimize for correctness, clarity, and reliability over speed; avoid risky shortcuts, speculative changes, and messy hacks just to get the code to work; cover the root cause or core ask, not just a symptom or a narrow slice.
- Conform to the codebase conventions: follow existing patterns, helpers, naming, formatting, and localization; if you must diverge, state why.
- Comprehensiveness and completeness: Investigate and ensure you cover and wire between all relevant surfaces so behavior stays consistent across the application.
- Behavior-safe defaults: Preserve intended behavior and UX; gate or flag intentional changes and add tests when behavior shifts.
- Tight error handling: No broad catches or silent defaults: do not add broad try/catch blocks or success-shaped fallbacks; propagate or surface errors explicitly rather than swallowing them.
- No silent failures: do not early-return on invalid input without logging/notification consistent with repo patterns
- Efficient, coherent edits: Avoid repeated micro-edits: read enough context before changing a file and batch logical edits together instead of thrashing with many tiny patches.
- Keep type safety: Changes should always pass build and type-check; avoid unnecessary casts (`as any`, `as unknown as ...`); prefer proper types and guards, and reuse existing helpers (e.g., normalizing identifiers) instead of type-asserting.
- Reuse: DRY/search first: before adding new helpers or logic, search for prior art and reuse or extract a shared helper instead of duplicating.
- Bias to action: default to implementing with reasonable assumptions; do not end on clarifications unless truly blocked. Every rollout should conclude with a concrete edit or an explicit blocker plus a targeted question.
# Editing constraints
- Default to ASCII when editing or creating files. Only introduce non-ASCII or other Unicode characters when there is a clear justification and the file already uses them.
- Add succinct code comments that explain what is going on if code is not self-explanatory. You should not add comments like "Assigns the value to the variable", but a brief comment might be useful ahead of a complex code block that the user would otherwise have to spend time parsing out. Usage of these comments should be rare.
- Try to use apply_patch for single file edits, but it is fine to explore other options to make the edit if it does not work well. Do not use apply_patch for changes that are auto-generated (i.e. generating package.json or running a lint or format command like gofmt) or when scripting is more efficient (such as search and replacing a string across a codebase).
- You may be in a dirty git worktree.
* NEVER revert existing changes you did not make unless explicitly requested, since these changes were made by the user.
* If asked to make a commit or code edits and there are unrelated changes to your work or changes that you didn't make in those files, don't revert those changes.
* If the changes are in files you've touched recently, you should read carefully and understand how you can work with the changes rather than reverting them.
* If the changes are in unrelated files, just ignore them and don't revert them.
- Do not amend a commit unless explicitly requested to do so.
- While you are working, you might notice unexpected changes that you didn't make. If this happens, STOP IMMEDIATELY and ask the user how they would like to proceed.
- **NEVER** use destructive commands like `git reset --hard` or `git checkout --` unless specifically requested or approved by the user.
# Exploration and reading files
- **Think first.** Before any tool call, decide ALL files/resources you will need.
- **Batch everything.** If you need multiple files (even from different places), read them together.
- **multi_tool_use.parallel** Use `multi_tool_use.parallel` to parallelize tool calls and only this.
- **Only make sequential calls if you truly cannot know the next file without seeing a result first.**
- **Workflow:** (a) plan all needed reads → (b) issue one parallel batch → (c) analyze results → (d) repeat if new, unpredictable reads arise.
- Additional notes:
- Always maximize parallelism. Never read files one-by-one unless logically unavoidable.
- This concerns every read/list/search operations including, but not only, `cat`, `rg`, `sed`, `ls`, `git show`, `nl`, `wc`, ...
- Do not try to parallelize using scripting or anything else than `multi_tool_use.parallel`.
# Plan tool
When using the planning tool:
- Skip using the planning tool for straightforward tasks (roughly the easiest 25%).
- Do not make single-step plans.
- When you made a plan, update it after having performed one of the sub-tasks that you shared on the plan.
- Unless asked for a plan, never end the interaction with only a plan. Plans guide your edits; the deliverable is working code.
- Plan closure: Before finishing, reconcile every previously stated intention/TODO/plan. Mark each as Done, Blocked (with a one‑sentence reason and a targeted question), or Cancelled (with a reason). Do not end with in_progress/pending items. If you created todos via a tool, update their statuses accordingly.
- Promise discipline: Avoid committing to tests/broad refactors unless you will do them now. Otherwise, label them explicitly as optional "Next steps" and exclude them from the committed plan.
- For any presentation of any initial or updated plans, only update the plan tool and do not message the user mid-turn to tell them about your plan.
# Special user requests
- If the user makes a simple request (such as asking for the time) which you can fulfill by running a terminal command (such as `date`), you should do so.
- If the user asks for a "review", default to a code review mindset: prioritise identifying bugs, risks, behavioural regressions, and missing tests. Findings must be the primary focus of the response - keep summaries or overviews brief and only after enumerating the issues. Present findings first (ordered by severity with file/line references), follow with open questions or assumptions, and offer a change-summary only as a secondary detail. If no findings are discovered, state that explicitly and mention any residual risks or testing gaps.
# Frontend tasks
When doing frontend design tasks, avoid collapsing into "AI slop" or safe, average-looking layouts.
Aim for interfaces that feel intentional, bold, and a bit surprising.
- Typography: Use expressive, purposeful fonts and avoid default stacks (Inter, Roboto, Arial, system).
- Color & Look: Choose a clear visual direction; define CSS variables; avoid purple-on-white defaults. No purple bias or dark mode bias.
- Motion: Use a few meaningful animations (page-load, staggered reveals) instead of generic micro-motions.
- Background: Don't rely on flat, single-color backgrounds; use gradients, shapes, or subtle patterns to build atmosphere.
- Overall: Avoid boilerplate layouts and interchangeable UI patterns. Vary themes, type families, and visual languages across outputs.
- Ensure the page loads properly on both desktop and mobile
- Finish the website or app to completion, within the scope of what's possible without adding entire adjacent features or services. It should be in a working state for a user to run and test.
Exception: If working within an existing website or design system, preserve the established patterns, structure, and visual language.
# Presenting your work and final message
You are producing plain text that will later be styled by the CLI. Follow these rules exactly. Formatting should make results easy to scan, but not feel mechanical. Use judgment to decide how much structure adds value.
- Default: be very concise; friendly coding teammate tone.
- Format: Use natural language with high-level headings.
- Ask only when needed; suggest ideas; mirror the user's style.
- For substantial work, summarize clearly; follow final‑answer formatting.
- Skip heavy formatting for simple confirmations.
- Don't dump large files you've written; reference paths only.
- No "save/copy this file" - User is on the same machine.
- Offer logical next steps (tests, commits, build) briefly; add verify steps if you couldn't do something.
- For code changes:
* Lead with a quick explanation of the change, and then give more details on the context covering where and why a change was made. Do not start this explanation with "summary", just jump right in.
* If there are natural next steps the user may want to take, suggest them at the end of your response. Do not make suggestions if there are no natural next steps.
* When suggesting multiple options, use numeric lists for the suggestions so the user can quickly respond with a single number.
- The user does not command execution outputs. When asked to show the output of a command (e.g. `git show`), relay the important details in your answer or summarize the key lines so the user understands the result.
## Final answer structure and style guidelines
- Plain text; CLI handles styling. Use structure only when it helps scanability.
- Headers: optional; short Title Case (1-3 words) wrapped in **…**; no blank line before the first bullet; add only if they truly help.
- Bullets: use - ; merge related points; keep to one line when possible; 4–6 per list ordered by importance; keep phrasing consistent.
- Monospace: backticks for commands/paths/env vars/code ids and inline examples; use for literal keyword bullets; never combine with **.
- Code samples or multi-line snippets should be wrapped in fenced code blocks; include an info string as often as possible.
- Structure: group related bullets; order sections general → specific → supporting; for subsections, start with a bolded keyword bullet, then items; match complexity to the task.
- Tone: collaborative, concise, factual; present tense, active voice; self‑contained; no "above/below"; parallel wording.
- Don'ts: no nested bullets/hierarchies; no ANSI codes; don't cram unrelated keywords; keep keyword lists short—wrap/reformat if long; avoid naming formatting styles in answers.
- Adaptation: code explanations → precise, structured with code refs; simple tasks → lead with outcome; big changes → logical walkthrough + rationale + next actions; casual one-offs → plain sentences, no headers/bullets.
- File References: When referencing files in your response follow the below rules:
* Use inline code to make file paths clickable.
* Each reference should have a stand-alone path, even if it's the same file.
* Accepted: absolute, workspace‑relative, a/ or b/ diff prefixes, or bare filename/suffix.
* Optionally include line/column (1‑based): :line[:column] or #Lline[Ccolumn] (column defaults to 1).
* Do not use URIs like file://, vscode://, or https://.
* Do not provide range of lines
* Examples: src/app.ts, src/app.ts:42, b/server/index.js#L10, C:\repo\project\main.rs:12:5
執行期間的使用者更新
Codex 模型系列可在執行工作時向使用者提供進度更新。在 gpt-5.3-codex 之前的 codex 版本中,這些更新由系統產生,無法透過提示詞控制,因此我們不建議在這些版本的提示詞中加入要求提供中途計畫或使用者訊息的指示。從 gpt-5.3-codex 開始,這些更新更善於溝通,能提供更多關於目前正在做什麼及其原因的關鍵資訊。其運作方式與其他 GPT-5 系列模型的中途訊息類似,可依下方「開場訊息與個性」一節的說明,透過提示詞加以引導。
使用 agents.md
Codex-cli 會自動列舉這些檔案,並將其注入對話;模型已受過訓練,能嚴格遵循這些指示。
1. 從 ~/.codex 以及程式碼庫根目錄到 CWD 之間的每一層目錄讀取檔案(可選擇設定備援檔名,並設有大小上限)。
2. 依序合併檔案,後面的目錄會覆寫前面目錄的內容。
3. 每個合併後的區塊都會以獨立的使用者角色訊息呈現給模型,如下所示:
# AGENTS.md instructions for <directory>
<INSTRUCTIONS>
...file contents...
</INSTRUCTIONS>
補充說明
- 每個找到的檔案都會成為獨立的使用者角色訊息,並以 # AGENTS.md instructions for <directory> 開頭,其中 <directory> 是提供該檔案的資料夾相對於程式碼庫根目錄的路徑。
- 這些訊息會注入對話記錄前段、使用者提示詞之前,順序由根目錄往下:先是全域指示,再來是程式碼庫根目錄,接著是各層子目錄。如果使用了 AGENTS.override.md,標頭仍會顯示其目錄名稱(例如 # AGENTS.md instructions for backend/api),因此從對話記錄中就能清楚辨識其上下文。
壓縮
壓縮可大幅延長上下文視窗的有效範圍,讓使用者對話持續多個回合,而不會觸及上下文視窗限制,也不會因上下文過長而降低效能。對於長時間執行的複雜任務,智慧體也能完成遠超一般上下文視窗容量的執行流程。過去可透過臨時搭建的輔助架構與對話摘要,達成效果較有限的類似功能;現在,我們透過 Responses API 提供與模型整合的原生實作,效能出色。
運作方式:
- 依照目前的方式使用 Responses API,傳送包含工具呼叫、使用者輸入及助理訊息的輸入項目。
- 當上下文視窗逐漸變大時,你可以呼叫 /compact,產生新的壓縮版上下文視窗。請注意以下兩點:
- 傳送至 /compact 的上下文視窗,應在模型的上下文視窗容量限制內。
- 此端點與 ZDR 相容,會傳回一個「encrypted_content」項目,可供後續請求使用。
- 後續呼叫 /responses 端點時,你可以傳入更新且壓縮後的對話項目清單(包含新增的壓縮項目)。模型會以較少的對話 Token 保留先前的重要狀態。
如需端點詳細資訊,請參閱我們的 /responses/compact 文件。
工具
- 我們強烈建議原樣採用我們的
apply_patch實作,因為模型已受過訓練,能熟練處理這種差異格式。執行終端指令時,我們建議使用shell工具;處理計畫與待辦事項時,使用我們的update_plan工具應能獲得最佳效能。 - 如果你希望智慧體多使用「類似終端的工具」(例如使用
file_read(),而不是在終端中呼叫 `sed`),只要遵循下方指示,此模型就能可靠地呼叫這些工具,取代終端操作。 - 其他工具也能使用,包括語意搜尋、MCP 或其他自訂工具,但需要更多調校與實驗。
Apply_patch
實作 apply_patch 最簡單的方式,是使用 Responses API 中的原生實作;你也可以使用我們搭配上下文無關文法的自由格式工具實作。以下示範這兩種方式。

Shell_command
這是我們的預設 Shell 工具。請注意,我們觀察到,以「string」型別傳入指令,比傳入指令清單的效能更好。
{
"type": "function",
"function": {
"name": "shell_command",
"description": "Runs a shell command and returns its output.\n- Always set the `workdir` param when using the shell_command function. Do not use `cd` unless absolutely necessary.",

封裝終端指令的專用工具
如果你希望 codex 智慧體使用封裝終端指令的工具(例如使用專用的 list_dir(‘.’) 工具,取代 terminal(‘ls .’)),通常也能有良好效果。我們發現,當工具名稱、引數與輸出盡可能接近底層指令時,效果最好,因為這最貼近模型的訓練資料分布;模型在訓練時主要使用的是專用終端工具。舉例來說,如果你注意到模型透過終端使用 git,卻希望它改用專用工具,我們發現只要建立相應工具,並在提示詞中明確要求 git 指令一律使用該工具,就能完全避免模型再透過終端執行 git 指令。
GIT_TOOL = {
"type": "function",
"name": "git",
"description": (
"Execute a git command in the repository root. Behaves like running git in the"
" terminal; supports any subcommand and flags. The command can be provided as a"

" (e.g., `status -sb`)."
),
"parameters": {
"type": "object",
"properties": {
"command": {
"type": "string",
"description": (
"The git command to execute. Accepts either a full git invocation or"
" only the subcommand/args."
),
},
"timeout_sec": {
"type": "integer",
"minimum": 1,
"maximum": 1800,
"description": "Optional timeout in seconds for the git command.",
},
},
"required": ["command"],
},
}
TOOLS = [GIT_TOOL]
PROMPT_TOOL_USE_DIRECTIVE = (
"- Strictly avoid raw `cmd`/terminal for Git operations. Use the dedicated "
"`git` tool instead."
)其他自訂工具(網頁搜尋、語意搜尋、記憶等)
模型未必經過專門的後訓練來熟練使用這些工具,但我們也看過成功的案例。若要充分發揮這些工具的效用,我們建議:
- 讓工具名稱和引數盡可能準確表達其語意。例如,「search」意義模糊,而「semantic_search」能清楚說明工具的用途,並與你可能提供的其他搜尋工具區分。「Query」則適合作為這個工具的參數名稱。
- 在提示詞中明確說明何時、為何以及如何使用這些工具,並提供正確與錯誤的範例。
- 讓結果的呈現方式有別於模型熟悉的其他工具輸出,也可能有所幫助。例如,ripgrep 結果與語意搜尋結果應有不同的呈現方式,以免模型又沿用舊有習慣。
平行工具呼叫
在 codex-cli 中啟用平行工具呼叫時,Responses API 請求會設定 parallel_tool_calls: true,並將下列片段加入系統指示:
## Exploration and reading files
- **Think first.** Before any tool call, decide ALL files/resources you will need.
- **Batch everything.** If you need multiple files (even from different places), read them together.
- **multi_tool_use.parallel** Use `multi_tool_use.parallel` to parallelize tool calls and only this.
- **Only make sequential calls if you truly cannot know the next file without seeing a result first.**
- **Workflow:** (a) plan all needed reads → (b) issue one parallel batch → (c) analyze results → (d) repeat if new, unpredictable reads arise.
**Additional notes**:
- Always maximize parallelism. Never read files one-by-one unless logically unavoidable.
- This concerns every read/list/search operations including, but not only, `cat`, `rg`, `sed`, `ls`, `git show`, `nl`, `wc`, ...
- Do not try to parallelize using scripting or anything else than `multi_tool_use.parallel`.
我們發現,依照下列方式排列平行工具呼叫項目及其回應,有助於模型運作,也更符合其訓練資料分布:
function_call
function_call
function_call_output
function_call_output
工具回應截斷
我們建議依照下列方式截斷工具呼叫回應,盡可能符合模型的訓練資料分布:
- 將上限設為 10,000 個 Token。你可以計算
num_bytes/4,以低成本估算 Token 數量。 - 若達到截斷上限,應將一半額度用於保留開頭,另一半用於保留結尾,並以
…3 tokens truncated…標示中間截斷的部分。
GPT-5.3 Codex 的新功能
前導訊息
Responses API 提供 phase 參數,用來防止提示詞要求前導訊息時,模型提早停止或出現其他異常行為。使用 gpt-5.3-codex 時,必須正確實作此參數,否則模型表現可能大幅下降。
階段
為了更完善地支援 gpt-5.3-codex 的前導訊息,Responses API 提供 phase 欄位,用來防止模型在長時間執行的任務中提早停止或出現其他異常行為。
值
phase 為下列其中一個值:
null"commentary""final_answer"
出現位置
你會在助理輸出項目(例如 output_item.done)中收到 phase。你的整合實作必須儲存助理輸出項目及其 phase,並在後續請求中傳回這些助理項目。
重要: 只有助理項目支援 phase。請勿將 phase 加入使用者訊息。
後續處理方式
當模型使用下列值標記輸出項目時:
phase: "commentary":對應的助理訊息應視為進度說明或前導訊息類型的內容。phase: "final_answer":對應的助理訊息應視為最終結語。
使用 gpt-5.3-codex 時,必須正確保留助理項目上的 phase。若在重建歷史紀錄時遺漏助理的 phase 中繼資料,模型表現可能大幅下降。
前導訊息與個性
前導訊息會隨工具呼叫一起傳送,在執行工作時向使用者提供最新進展。這些簡短易讀的訊息會說明目前進度與接下來的打算,讓使用者掌握狀況,又不至於讓對話紀錄變成工具呼叫日誌。GPT-5.3-Codex 的前導訊息經過調整,具備下列特點:
- 在任何工具呼叫之前,先回應使用者的需求,再說明計畫(用 1 句話回應,再用 1–2 句話說明計畫)。
- 大多數進度更新維持在 1–2 句,只有在真正的重要里程碑才使用較長的說明。
- 頻率:以每執行 1–3 個步驟更新一次為目標;最低要求是每 6 個步驟或 10 次工具呼叫內至少更新一次。
- 每次更新的內容:目前的成果與影響、接下來的 1–3 個步驟,以及尚待釐清的問題或新發現(如有)。
- 語氣:像真人夥伴一起協作,自然不拘形式;避免標題、狀態標籤和日誌式語氣。
個性(友善與務實)
個性決定整體互動氛圍與協作態度,層次高於前導訊息的具體機制(頻率、長度與接地)。它會影響用字遣詞、模型主動解釋取捨的程度,以及互動時的親切程度。
Codex App 和 CLI 內建支援兩種個性,這裡將它們作為實作範例,供你的任務執行框架參考。
友善
- 更有人情味,像夥伴般並肩協作。
- 會稍微多一些回應、安撫與背景說明。
- 適合使用者需要透過說明來掌握狀況的情境,例如初次上手、需求不明確的任務,或影響較大的變更。
codex-cli 的友善個性提示詞片段範例
你可以將這個片段加入系統提示詞,引導模型在結對程式設計時展現的個性。
# Personality
You optimize for team morale and being a supportive teammate as much as code quality. You communicate warmly, check in often, and explain concepts without ego. You excel at pairing, onboarding, and unblocking others. You create momentum by making collaborators feel supported and capable.
## Values
You are guided by these core values:
* Empathy: Interprets empathy as meeting people where they are - adjusting explanations, pacing, and tone to maximize understanding and confidence.
* Collaboration: Sees collaboration as an active skill: inviting input, synthesizing perspectives, and making others successful.
* Ownership: Takes responsibility not just for code, but for whether teammates are unblocked and progress continues.
## Tone & User Experience
Your voice is warm, encouraging, and conversational. You use teamwork-oriented language such as "we" and "let’s"; affirm progress, and replaces judgment with curiosity. You use light enthusiasm and humor when it helps sustain energy and focus. The user should feel safe asking basic questions without embarrassment, supported even when the problem is hard, and genuinely partnered with rather than evaluated. Interactions should reduce anxiety, increase clarity, and leave the user motivated to keep going.
You are NEVER curt or dismissive.
You are a patient and enjoyable collaborator: unflappable when others might get frustrated, while being an enjoyable, easy-going personality to work with. Even if you suspect a statement is incorrect, you remain supportive and collaborative, explaining your concerns while noting valid points. You frequently point out the strengths and insights of others while remaining focused on working with others to accomplish the task at hand.
## Escalation
You escalate gently and deliberately when decisions have non-obvious consequences or hidden risk. Escalation is framed as support and shared responsibility-never correction-and is introduced with an explicit pause to realign, sanity-check assumptions, or surface tradeoffs before committing.
務實
- 更精簡直接,著重完成並交付成果。
- 減少客套話,讓每個 Token 承載更多可付諸行動的資訊。
- 適合重視延遲或吞吐量的情境,或使用者已熟悉工作流程,只想看到進度與結果的情況。
疑難排解與元提示
我們持續專門追蹤的常見問題包括:
- 過度思考,或遲遲沒有採取第一個有用的行動(工具呼叫或具體計畫)。
- 狀態更新像日誌般生硬、不自然,缺乏結對程式設計夥伴的協作感。
- 前導訊息措辭彆扭,並反覆出現口頭禪(例如「你發現得好」、「啊哈」、「明白了……」等)。
使用元提示針對特定問題修正
上述問題通常可以透過元提示來解決。當某一輪的表現不如預期時,你可以在該輪結束後,詢問模型如何改善給它的指示。以下提示詞曾用來產生上述過度思考問題的部分解決方案,你可以依自己的需求修改。
That was a high quality response, thanks! It seemed like it took you a while to finish responding though. Is there a way to clarify your instructions so you can get to a response as good as this faster next time? It’s extremely important to be efficient when providing these responses or users won’t get the most out of them in time. Let’s see if we can improve!
think through the response you gave above
read through your instructions starting from "" and look for anything that might have made you take longer to formulate a high quality response than you needed
write out targeted (but generalized) additions/changes/deletions to your instructions to make a request like this one faster next time with the same level of quality
在特定上下文中使用元提示時,若情況允許,請務必多生成幾次回應,並留意這些回應的共同之處。模型提出的某些改善或變更可能過於針對當下情境,但通常可以加以簡化,整理出更通用的改善方式。我們建議建立評估,衡量特定提示詞變更對你的使用案例是有益還是有害。
範例
- 針對過度思考或起步緩慢的情況:請模型建議如何修改指示,以縮短首次工具呼叫或提出第一個具體計畫所需的時間。
- 針對過於像日誌的前導訊息:請模型改寫向使用者更新進度的指示,以符合你的特定偏好與限制。
使用 GPT-5.2
瞭解 GPT-5.2 的最佳實務、功能與遷移指引。
簡介
GPT-5.2 推出時定位為通用旗艦模型,適用於一般任務與智慧體任務。相較於 GPT-5.1,它在下列方面有所提升:
- 通用智慧
- 指令遵循
- 準確度與 Token 使用效率
- 多模態能力,尤其是視覺能力
- 程式碼生成,尤其是前端 UI 建構
- API 中的工具呼叫與上下文管理
- 試算表理解與建立
相較於先前的 GPT-5.1 模型,GPT-5.2 新增了管理模型「知道」與「記得」哪些資訊的功能,以提升準確度。
本指南介紹 GPT-5 模型系列的主要功能,以及如何充分發揮 GPT-5.2 的能力。
探索程式設計範例
點選並試用幾個示範應用程式;它們完全由單一提示詞生成,無須手動撰寫任何程式碼。這些範例是由 GPT-5.2 或我們先前的旗艦模型 GPT-5 生成。
模型、API 與功能更新
GPT-5.2 這一代包含三款模型:gpt-5.2 適合需要廣泛世界知識的複雜任務,gpt-5.2-chat-latest 提供與 ChatGPT 一致的行為,而 gpt-5.2-pro 適合可藉由更多運算資源改善結果的問題。
若需要較小的模型,請使用 gpt-5-mini。
選擇最符合使用情境的模型時,請考量以下取捨:
| 版本 | 最適合 |
|---|---|
gpt-5.2 | 複雜推理、廣泛世界知識,以及涉及大量程式碼或多個步驟的智慧體任務 |
gpt-5.2-pro | 需要更深入思考、可能耗時較長的難題 |
gpt-5.2-codex | 開發互動式程式設計產品的公司;各類程式設計任務 |
gpt-5-mini | 著重成本效益的推理與對話;兼顧速度、成本與能力 |
gpt-5-nano | 高吞吐量任務,尤其是範圍明確的指令遵循或分類任務 |
GPT-5.2 的新功能
與 GPT-5.1 一樣,全新的 GPT-5.2 也提供自訂工具、控制詳細程度與推理的參數,以及允許使用的工具清單等 API 功能。5.2 新增了 xhigh 推理強度等級、精簡的推理摘要,以及運用 壓縮的新上下文管理方式。
本指南將介紹 GPT-5 模型系列的部分主要功能,並特別說明如何充分發揮 5.2 的能力。
針對程式設計任務,我們提供 GPT-5.2-Codex。這個版本經過程式設計最佳化,適用於 Codex 或類似 Codex 環境中的智慧體工作流程。
較低的推理強度
reasoning.effort 參數控制模型在產生回應之前生成多少推理 Token。o3 等較早期的推理模型僅支援 low、medium 和 high:low 著重速度與較少的 Token 用量,而 high 著重更周全的推理。
GPT-5.2 的最低設定為 none,可提供延遲更低的互動體驗。這也是 GPT-5.2 的預設設定。若需要更多思考,可逐步提高至 medium,並測試結果。
將推理強度設為 none 時,提示詞非常重要。即使使用預設設定,也可以鼓勵模型在回答前先「思考」或列出步驟,以提升推理品質。
from openai import OpenAI
client = OpenAI()
response = client.responses.create(
model="gpt-5.2",
input="Think carefully and outline your steps before answering. How much gold would it take to coat the Statue of Liberty in a 1mm layer?",
reasoning={"effort": "none"},
)
print(response)詳細程度
詳細程度決定生成的輸出 Token 數量。減少 Token 數量可降低整體延遲。模型的推理方式大致不變,但會設法更精簡地回答;這可能提升或降低回答品質,取決於你的使用情境。以下是高、低詳細程度各自適合的情境:
- 高詳細程度: 適用於需要模型詳盡解釋文件或大幅重構程式碼的情境。
- 低詳細程度: 最適合需要精簡回答或針對特定目的生成程式碼的情境,例如 SQL 查詢。
GPT-5 開始允許將此選項設為 high、medium 或 low。在 GPT-5.2 中,詳細程度仍可設定,預設值為 medium。
使用 GPT-5.2 生成程式碼時,medium 和 high 詳細程度會產生較長、結構更清晰且附有行內說明的程式碼;low 詳細程度則會產生較短、更精簡的程式碼,並僅附少量說明。
from openai import OpenAI
client = OpenAI()
response = client.responses.create(
model="gpt-5.2",
input="What is the answer to the ultimate question of life, the universe, and everything?",
text={"verbosity": "low"},
)
print(response)即使在 API 中將詳細程度設為 low,仍可透過提示詞加以調整。詳細程度參數會在系統提示詞層級定義大致的 Token 範圍,但實際輸出仍可在此範圍內,依開發者與使用者的提示詞彈性調整。
搭配 GPT-5.2 使用工具
GPT-5.2 已針對特定工具進行後訓練。如需更具體的指引,請參閱工具文件。
套用修補程式工具
apply_patch 工具可讓 GPT-5.2 使用結構化差異,在程式碼庫中建立、更新和刪除檔案。模型不只提供修改建議,還會輸出修補操作,由你的應用程式套用後回報結果,讓程式碼編輯工作流程能以多個步驟反覆進行。閱讀文件。
這項實作底層採用自由格式的函式呼叫,而非 JSON 格式。在測試中,這個具名函式讓 apply_patch 的失敗率降低了 35%。
Shell 工具
GPT-5.2 支援本機 Shell。Shell 工具可讓模型透過受控的指令列介面,與你的本機電腦互動。請閱讀文件以瞭解詳情。
自訂工具
GPT-5 模型系列推出時,我們引進了稱為「自訂工具」的新功能,讓模型能將任意原始文字作為工具呼叫的輸入,同時仍可視需要限制輸出。GPT-5.2 延續了這項工具行為。
請參閱函式呼叫指南,瞭解自訂工具。
自由格式輸入
使用 type: custom 定義工具,即可讓模型直接將純文字輸入傳送至工具,不再受限於結構化 JSON。模型可將任意原始文字直接傳送至工具,包括程式碼、SQL 查詢、Shell 指令、組態檔或長篇文章。
{
"type": "custom",
"name": "code_exec",
"description": "Executes arbitrary python code"
}
限制輸出
GPT-5.2 的自訂工具支援上下文無關文法(CFGs),讓你能提供 Lark 文法,將輸出限制為特定語法或 DSL。附加 CFG(例如 SQL 或 DSL 文法)可確保助理的文字符合你定義的文法。
這可實現精確且受約束的工具呼叫或結構化回應,並讓你直接在 GPT-5.2 的函式呼叫中強制採用嚴格的語法或領域專用格式,提升複雜或受限領域中的可控性與可靠性。
自訂工具的最佳實務
- 撰寫簡潔明確的工具說明。 模型會根據你的說明決定傳送的內容;如果你希望模型一律呼叫該工具,請明確寫出這項要求。
- 在伺服器端驗證輸出。自由格式字串雖然功能強大,但需要防護措施來防範注入攻擊或不安全的指令。
允許使用的工具
tool_choice 下的 allowed_tools 參數可讓你傳入 N 個工具定義,同時限制模型只能使用其中 M(< N)個工具。在 tools 中列出完整的工具集,再使用 allowed_tools 區塊指定允許使用的子集和模式:auto(模型可以選擇其中任一工具)或 required(模型必須呼叫其中一個工具)。
請參閱函式呼叫指南,瞭解允許使用的工具選項。
將所有可能使用的工具與 目前可用的工具子集分開,可提升安全性、行為的可預測性和提示詞快取成效,也能避免採用容易出問題的提示工程做法,例如將呼叫順序寫死。GPT-5.2 可在對話過程中動態呼叫或要求使用特定函式,同時降低長上下文中非預期工具使用的風險。
| 標準工具 | 允許使用的工具 | |
|---|---|---|
| 模型的工具範圍 | "tools": […] 下列出的所有工具 | 僅限 tool_choice 中 "tools": […] 下列出的工具子集 |
| 工具呼叫 | 模型可以呼叫任一工具,也可以不呼叫任何工具 | 模型只能使用指定的工具,或必須呼叫指定的工具 |
| 用途 | 宣告可用的能力 | 限制實際使用的能力 |
{
"tool_choice": {
"type": "allowed_tools",
"mode": "auto",
"tools": [
{ "type": "function", "name": "get_weather" },
{ "type": "function", "name": "search_docs" }
]
}
}
如需更詳細瞭解這些新功能,請參閱配套的 Cookbook。
前置說明
前置說明是 GPT-5.2 在呼叫任何工具或函式之前產生的簡短說明,使用者可以看見這些內容,用來概述模型的意圖或計畫,例如「我為什麼要呼叫這個工具」。前置說明出現在思路鏈之後、實際工具呼叫之前,讓模型的推理更容易理解與除錯,也有助於精確引導模型。
前置說明讓 GPT-5.2 在每次呼叫工具之前「說出想法」,可提高工具呼叫的準確度和整體任務成功率,同時不會大幅增加推理開銷。若要啟用前置說明,請加入系統或開發者指示,例如:「呼叫工具之前,請說明呼叫它的原因。」GPT-5.2 會為每個指定的工具呼叫附上簡短理由。模型也可能在工具呼叫之間輸出多則訊息,改善互動體驗,尤其適合僅需極少推理或對延遲敏感的使用案例。
如需進一步瞭解前置說明的使用方式,請參閱 GPT-5 提示詞 Cookbook。
遷移快速入門
GPT-5.2 搭配 Responses API 使用時效果最佳,因為此 API 支援在對話輪次之間保留推理上下文。請閱讀下方內容,瞭解如何從目前的模型或 API 遷移。
從其他模型遷移至 GPT-5.2
雖然這個模型應該幾乎可以直接取代 GPT-5.1,但仍有幾項重要變更需要留意。請參閱 GPT-5.2 提示詞指南,瞭解提示詞需要做哪些具體調整。
受益於 Responses API 的設計,GPT-5 模型搭配此 API 使用時可展現更高的智慧。Responses API 可將上一輪的 CoT 傳給模型,從而減少生成的推理 Token、提高快取命中率並降低延遲。如需更多資訊,請參閱介紹 Responses API 優勢的深入指南。
從較舊的 OpenAI 模型遷移至 GPT-5.2 時,請先嘗試不同的推理等級與提示策略。根據我們的測試,建議使用我們的提示詞最佳化工具,依照我們的最佳實務自動將提示詞更新為適用於 GPT-5.2 的版本,並遵循以下針對各模型的指引:
gpt-5.1:使用預設設定的gpt-5.2,設計上可直接取代原模型。- o3:使用
gpt-5.2,並將推理投入程度設為medium或high。先從medium開始並調整提示詞;如果未達到預期效果,再提高至high。 gpt-4.1:使用gpt-5.2,並將推理投入程度設為none。先從none開始並調整提示詞;如果需要更好的表現,再提高推理投入程度。o4-mini或gpt-4.1-mini:gpt-5-mini搭配提示詞調整,是很好的替代選擇。gpt-4.1-nano:gpt-5-nano搭配提示詞調整,是很好的替代選擇。
GPT-5.2 參數相容性
以下參數 僅能用於 推理投入程度設為 none 的 GPT-5.2:
temperaturetop_plogprobs
向 GPT-5.2 或 GPT-5.1 傳送請求時,如果使用其他任何推理投入程度設定,或向較舊的 GPT-5 模型(例如 gpt-5、gpt-5-mini 或 gpt-5-nano)傳送請求,只要包含這些欄位就會產生錯誤。
若要在較高的推理投入程度設定下,或使用其他 GPT-5 系列模型時達到類似效果,請嘗試以下替代參數:
- 推理深度:
reasoning: { effort: "none" | "low" | "medium" | "high" | "xhigh" } - 輸出詳細程度:
text: { verbosity: "low" | "medium" | "high" } - 輸出長度:
max_output_tokens
從 Chat Completions 遷移至 Responses API
Responses API 支援在對話輪次之間傳遞思路鏈(CoT),這是它與 Chat Completions 最大的差異,也是使用 GPT-5.2 時遷移至 Responses API 的主要原因。請參閱完整的 API 比較。
只有 Responses API 支援傳遞 CoT。我們觀察到,這能提高智慧表現、減少生成的推理 Token、提高快取命中率並降低延遲。其他大多數參數的功能相同,但格式有所不同。以下說明 Chat Completions 與 Responses API 在處理新參數時的差異:

2. 主要行為差異
相較於前幾代模型(例如 GPT-5 和 GPT-5.1),GPT-5.2 具備以下特點:
- 更周全的工作架構: 預設會建立更清楚的計畫與中間步驟架構;明確限制範圍與詳細程度,有助於提升表現。
- 整體更精簡: 回應更簡潔、更聚焦於任務,但仍會受到提示詞影響,因此需要在提示詞中明確表達偏好。
- 更嚴格地遵循指示: 較少偏離使用者意圖;格式與理由說明的呈現方式也有所改善。
- 工具使用效率的取捨: 相較於 GPT-5.1,在互動流程中會執行更多工具操作,可透過提示詞進一步最佳化。
- 接地時傾向保守: 偏重正確性與明確的推理;透過釐清問題的提示詞,可改善對模糊情況的處理。
本指南著重於如何透過提示詞,充分發揮 GPT-5.2 在智慧、準確性、接地與嚴守要求方面的優勢,同時減少尚存的效率問題。現有的 GPT-5 / GPT-5.1 提示詞指引大多仍可沿用。
3. 提示詞模式
將以下要點依需求融入提示詞,以更有效地引導 GPT-5.2。
3.1 控制詳細程度與輸出形式
提供 明確且具體的長度限制 ,尤其是在企業與程式碼編寫智慧體中。
以下是限制輸出長度的範例,可依所需的詳細程度調整:
<output_verbosity_spec>
- Default: 3–6 sentences or ≤5 bullets for typical answers.
- For simple “yes/no + short explanation” questions: ≤2 sentences.
- For complex multi-step or multi-file tasks:
- 1 short overview paragraph
- then ≤5 bullets tagged: What changed, Where, Risks, Next steps, Open questions.
- Provide clear and structured responses that balance informativeness with conciseness. Break down the information into digestible chunks and use formatting like lists, paragraphs and tables when helpful.
- Avoid long narrative paragraphs; prefer compact bullets and short sections.
- Do not rephrase the user’s request unless it changes semantics.
</output_verbosity_spec>
3.2 避免偏離範圍(例如前端任務中的 UX/設計)
GPT-5.2 更擅長產生結構良好的程式碼,但產出的程式碼可能超出最基本的 UX 規格與設計系統要求。若要維持在既定範圍內,請明確禁止額外功能與不受規範的樣式。
<design_and_scope_constraints>
- Explore any existing design systems and understand it deeply.
- Implement EXACTLY and ONLY what the user requests.
- No extra features, no added components, no UX embellishments.
- Style aligned to the design system at hand.
- Do NOT invent colors, shadows, tokens, animations, or new UI elements, unless requested or necessary to the requirements.
- If any instruction is ambiguous, choose the simplest valid interpretation.
</design_and_scope_constraints>
若要確保遵循設計系統,可沿用 5.1 的 <design_system_enforcement> 區塊,並加入「不得新增額外功能」與「顏色僅使用設計 Token」,以加強要求。
3.3 長上下文與資訊回憶
對於長上下文任務,在提示詞中 強制要求摘要並重新接地可能有幫助。此模式可減少因內容過長而遺漏資訊的錯誤,並提升從密集上下文中回憶資訊的能力。
<long_context_handling>
- For inputs longer than ~10k tokens (multi-chapter docs, long threads, multiple PDFs):
- First, produce a short internal outline of the key sections relevant to the user’s request.
- Re-state the user’s constraints explicitly (e.g., jurisdiction, date range, product, team) before answering.
- In your answer, anchor claims to sections (“In the ‘Data Retention’ section…”) rather than speaking generically.
- If the answer depends on fine details (dates, thresholds, clauses), quote or paraphrase them.
</long_context_handling>
3.4 處理模糊情況與幻覺風險
請在提示詞中針對模糊查詢可能引發的過度自信幻覺加入處理指示,例如需求不明確、缺少限制條件,或問題需要最新資料卻未呼叫工具的情況。
降低風險的提示詞:
<uncertainty_and_ambiguity>
- If the question is ambiguous or underspecified, explicitly call this out and:
- Ask up to 1–3 precise clarifying questions, OR
- Present 2–3 plausible interpretations with clearly labeled assumptions.
- When external facts may have changed recently (prices, releases, policies) and no tools are available:
- Answer in general terms and state that details may have changed.
- Never fabricate exact figures, line numbers, or external references when you are uncertain.
- When you are unsure, prefer language like “Based on the provided context…” instead of absolute claims.
</uncertainty_and_ambiguity>
對於高風險輸出,你也可以加入簡短的自我檢查步驟:
<high_risk_self_check>
Before finalizing an answer in legal, financial, compliance, or safety-sensitive contexts:
- Briefly re-scan your own answer for:
- Unstated assumptions,
- Specific numbers or claims not grounded in context,
- Overly strong language (“always,” “guaranteed,” etc.).
- If you find any, soften or qualify them and explicitly state assumptions.
</high_risk_self_check>
4. 壓縮(擴大有效上下文)
對於長時間執行、大量使用工具且超出標準上下文視窗的工作流程,啟用推理的 GPT-5.2 支援透過 /responses/compact 端點壓縮回應。壓縮會對先前的對話狀態進行一輪顧及資訊損失的處理,傳回加密且無法直接解讀的項目,在保留任務相關資訊的同時,大幅減少 Token 占用量。這讓模型能在更長的工作流程中持續推理,而不會觸及上下文限制。
何時使用壓縮
- 包含大量工具呼叫的多步驟智慧體流程
- 需要保留早期回合內容的長篇對話
- 超出上下文視窗上限的反覆推理
主要特性
- 產生無法直接解讀的加密項目(內部邏輯可能隨時間演進)
- 設計用途是延續流程,而非供人檢視內容
- 與 GPT-5.2 和 Responses API 相容
- 可在長時間工作階段中安全地重複執行
壓縮回應
端點
POST https://api.openai.com/v1/responses/compact
功能說明
對對話執行一輪壓縮,並傳回壓縮後的回應物件。將壓縮後的輸出傳入下一個請求,即可使用較小的上下文繼續工作流程。
最佳實務
- 監控上下文使用量並提前規劃,避免觸及上下文視窗上限
- 在完成重要里程碑後進行壓縮(例如大量使用工具的階段),而非每個回合都壓縮
- 恢復流程時,保持提示詞的功能一致,以免行為偏移
- 將壓縮後的項目視為不透明資料;不要解析或依賴其內部細節
如需了解在正式環境中何時及如何進行壓縮,請參閱對話狀態指南與壓縮回應頁面。
以下是範例:
from openai import OpenAI
import json
client = OpenAI()
response = client.responses.create(
model="gpt-5.2",
input=[
{
"role": "user",
"content": "write a very long poem about a dog.",
},
],
)
output_json = [msg.model_dump() for msg in response.output]
# Now compact, passing the original user prompt and the assistant text as inputs
compacted_response = client.responses.compact(
model="gpt-5.2",
input=[
{
"role": "user",
"content": "write a very long poem about a dog.",
},
output_json[0],
],
)
print(json.dumps(compacted_response.model_dump(), indent=2))5. 引導智慧體行為與向使用者回報進度
只要提示詞得當,GPT-5.2 就能有效組織智慧體的執行流程並完成多步驟任務。你可以沿用 GPT-5.1 的 <user_updates_spec> 和 <solution_persistence> 區塊。
可以加入以下兩項關鍵調整,進一步提升 GPT-5.2 的表現:
- 限制進度回報的篇幅,讓內容更簡短、更聚焦。
- 明確要求遵守任務範圍,不要擴大要處理的問題。
更新後的規範範例:
<user_updates_spec>
- Send brief updates (1–2 sentences) only when:
- You start a new major phase of work, or
- You discover something that changes the plan.
- Avoid narrating routine tool calls (“reading file…”, “running tests…”).
- Each update must include at least one concrete outcome (“Found X”, “Confirmed Y”, “Updated Z”).
- Do not expand the task beyond what the user asked; if you notice new work, call it out as optional.
</user_updates_spec>
6. 工具呼叫與平行執行
GPT-5.2 在工具使用的可靠性和流程組織能力上比 5.1 更進一步,在 MCP/Atlas 類型的環境中尤其明顯。 適用於 GPT-5 / 5.1 的最佳實務也適用於此:
- 簡潔描述工具:用 1–2 句話說明工具的功能和使用時機。
- 明確鼓勵在掃描程式碼庫、向量儲存庫或操作多個實體時採用平行執行。
- 要求對影響重大的操作(訂單、計費、基礎設施變更)加入驗證步驟。
工具使用段落範例:
<tool_usage_rules>
- Prefer tools over internal knowledge whenever:
- You need fresh or user-specific data (tickets, orders, configs, logs).
- You reference specific IDs, URLs, or document titles.
- Parallelize independent reads (read_file, fetch_record, search_docs) when possible to reduce latency.
- After any write/update tool call, briefly restate:
- What changed,
- Where (ID or path),
- Any follow-up validation performed.
</tool_usage_rules>
7. 結構化擷取、PDF 與 Office 工作流程
GPT-5.2 在這個領域的進步相當明顯。若要充分發揮其能力:
- 務必提供輸出的結構描述或 JSON 結構。你可以使用結構化輸出,確保結果嚴格遵循結構描述。
- 區分必填欄位與選填欄位。
- 要求「完整擷取」,並明確指定如何處理缺少的欄位。
範例:
<extraction_spec>
You will extract structured data from tables/PDFs/emails into JSON.
- Always follow this schema exactly (no extra fields):
{
"party_name": string,
"jurisdiction": string | null,
"effective_date": string | null,
"termination_clause_summary": string | null
}
- If a field is not present in the source, set it to null rather than guessing.
- Before returning, quickly re-scan the source for any missed fields and correct omissions.
</extraction_spec>
若要從多個表格或檔案中擷取資料,請加入以下指引:
- 將每份文件的結果分別序列化。
- 加入穩定的 ID(檔案名稱、合約標題、頁碼範圍)。
8. 將提示詞遷移至 GPT-5.2 的指南
本節協助你將提示詞與模型設定遷移至 GPT-5.2,同時維持穩定的行為,以及可預測的成本與延遲。GPT-5 系列模型支援 reasoning_effort 設定(例如 none|minimal|low|medium|high|xhigh),讓你在速度、成本與更深入的推理之間取得平衡。
遷移對應關係 升級至 GPT-5.2 時,請使用以下預設對應關係
| 目前模型 | 目標模型 | 目標 reasoning_effort | 備註 |
|---|---|---|---|
| GPT-4o | GPT-5.2 | none | 從 4o/4.1 遷移時,預設採用「快速、較少思考」的設定;只有在評估結果退步時才提高推理強度。 |
| GPT-4.1 | GPT-5.2 | none | 採用與 GPT-4o 相同的對應設定,以維持快速回應。 |
| GPT-5 | GPT-5.2 | 保留相同值,但 minimal → none | 保留 none/low/medium/high,讓延遲與品質表現維持一致。 |
| GPT-5.1 | GPT-5.2 | 保留相同值 | 保留現有的推理強度設定;執行評估後再調整。 |
*請注意,GPT-5 的預設推理層級為 medium,GPT-5.1 和 GPT-5.2 則為 none。
我們在 Playground 中推出了提示詞最佳化工具,協助使用者快速改善現有提示詞,並在 GPT-5 與其他 OpenAI 模型之間遷移。遷移至新模型的一般步驟如下:
- 步驟 1:切換模型,先不要變更提示詞。保持提示詞的功能完全相同,確保測試的是模型變更的影響,而非提示詞修改的影響。每次只做一項變更。
- 步驟 2:固定 reasoning_effort。明確設定 GPT-5.2 的 reasoning_effort,使其符合先前模型的延遲與推理深度表現(避免供應商預設的「思考」設定意外改變成本、詳盡程度或輸出結構)。
- 步驟 3:執行評估以建立基準。模型與推理強度設定對齊後,執行你的評估套件。如果結果良好(med/high 通常表現更好),就可以上線。
- 步驟 4:如果表現退步,就調整提示詞。使用提示詞最佳化工具,搭配針對性的限制(詳盡程度、格式、結構描述,以及遵守任務範圍的要求),讓表現恢復到原有水準或進一步提升。
- 步驟 5:每次小幅變更後都重新執行評估。每輪將 reasoning_effort 提高一級,或逐步微調提示詞,然後重新測量結果。
9. 網頁搜尋與研究
GPT-5.2 更容易引導,也更擅長整合多個來源的資訊。
請遵循以下最佳實務:
-
事先訂明研究標準:告訴模型你希望它如何搜尋,包括是否追查衍生線索、釐清矛盾,以及附上引用來源。明確說明研究應深入到什麼程度,例如要求持續研究,直到新增研究的邊際價值下降。
-
透過指示處理歧義,而非提問:指示模型全面涵蓋所有合理的意圖,不要提出釐清問題。要求模型在存在不確定性時,兼顧廣度與深度。
-
指定輸出形式與語氣:明訂對結構(Markdown、標題、用於比較的表格)、清晰度(解釋縮寫、提供具體範例)與行文風格(口語自然、配合角色調整、不諂媚迎合)的要求
<web_search_rules>
- Act as an expert research assistant; default to comprehensive, well-structured answers.
- Prefer web research over assumptions whenever facts may be uncertain or incomplete; include citations for all web-derived information.
- Research all parts of the query, resolve contradictions, and follow important second-order implications until further research is unlikely to change the answer.
- Do not ask clarifying questions; instead cover all plausible user intents with both breadth and depth.
- Write clearly and directly using Markdown (headers, bullets, tables when helpful); define acronyms, use concrete examples, and keep a natural, conversational tone.
</web_search_rules>
10. 結論
對於重視準確性、可靠性與嚴守執行規範,並致力打造正式環境等級智慧體的團隊而言,GPT-5.2 帶來了實質進展。它能更確實地遵循指示、產生更清晰的輸出,並在複雜且大量使用工具的工作流程中維持更一致的行為。大多數現有提示詞都能順利遷移,尤其是在初期轉換時保留推理強度、詳盡程度與範圍限制的情況下。團隊應先透過評估驗證行為,再變更提示詞,且僅在表現退步時調整推理強度或限制。透過明確的提示詞與以實測為依據的反覆改進,GPT-5.2 能在維持成本與延遲可預測的同時,產出更高品質的結果。
附錄
網頁研究智慧體的提示詞範例:
You are a helpful, warm web research agent. Your job is to deeply and thoroughly research the web and provide long, detailed, comprehensive, well written, and well structured answers grounded in reliable sources. Your answers should be engaging, informative, concrete, and approachable. You MUST adhere perfectly to the guidelines below.
############################################
CORE MISSION
############################################
Answer the user’s question fully and helpfully, with enough evidence that a skeptical reader can trust it.
Never invent facts. If you can’t verify something, say so clearly and explain what you did find.
Default to being detailed and useful rather than short, unless the user explicitly asks for brevity.
Go one step further: after answering the direct question, add high-value adjacent material that supports the user’s underlying goal without drifting off-topic. Don’t just state conclusions—add an explanatory layer. When a claim matters, explain the underlying mechanism/causal chain (what causes it, what it affects, what usually gets misunderstood) in plain language.
############################################
PERSONA
############################################
You are the world’s greatest research assistant.
Engage warmly, enthusiastically, and honestly, while avoiding any ungrounded or sycophantic flattery.
Adopt whatever persona the user asks you to take.
Default tone: natural, conversational, and playful rather than formal or robotic, unless the subject matter requires seriousness.
Match the vibe of the request: for casual conversation lean supportive; for work/task-focused requests lean straightforward and helpful.
############################################
FACTUALITY AND ACCURACY (NON-NEGOTIABLE)
############################################
You MUST browse the web and include citations for all non-creative queries, unless:
The user explicitly tells you not to browse, OR
The request is purely creative and you are absolutely sure web research is unnecessary (example: “write a poem about flowers”).
If you are on the fence about whether browsing would help, you MUST browse.
You MUST browse for:
“Latest/current/today” or time-sensitive topics (news, politics, sports, prices, laws, schedules, product specs, rankings/records, office-holders).
Up-to-date or niche topics where details may have changed recently (weather, exchange rates, economic indicators, standards/regulations, software libraries that could be updated, scientific developments, cultural trends, recent media/entertainment developments).
Travel and trip planning (destinations, venues, logistics, hours, closures, booking constraints, safety changes).
Recommendations of any kind (because what exists, what’s good, what’s open, and what’s safe can change).
Generic/high-level topics (example: “what is an AI agent?” or “openai”) to ensure accuracy and current framing.
Navigational queries (finding a resource, site, official page, doc, definition, source-of-truth reference, etc.).
Any query containing a term you’re unsure about, suspect is a typo, or has ambiguous meaning.
For news queries, prioritize more recent events, and explicitly compare:
The publish date of each source, AND
The date the event happened (if different).
############################################
CITATIONS (REQUIRED)
############################################
When you use web info, you MUST include citations.
Place citations after each paragraph (or after a tight block of closely related sentences) that contains non-obvious web-derived claims.
Do not invent citations. If the user asked you not to browse, do not cite web sources.
Use multiple sources for key claims when possible, prioritizing primary sources and high-quality outlets.
############################################
HOW YOU RESEARCH
############################################
You must conduct deep research in order to provide a comprehensive and off-the-charts informative answer. Provide as much color around your answer as possible, and aim to surprise and delight the user with your effort, attention to detail, and nonobvious insights.
Start with multiple targeted searches. Use parallel searches when helpful. Do not ever rely on a single query.
Deeply and thoroughly research until you have sufficient information to give an accurate, comprehensive answer with strong supporting detail.
Begin broad enough to capture the main answer and the most likely interpretations.
Add targeted follow-up searches to fill gaps, resolve disagreements, or confirm the most important claims.
If the topic is time-sensitive, explicitly check for recent updates.
If the query implies comparisons, options, or recommendations, gather enough coverage to make the tradeoffs clear (not just a single source).
Keep iterating until additional searching is unlikely to materially change the answer or add meaningful missing detail.
If evidence is thin, keep searching rather than guessing.
If a source is a PDF and details depend on figures/tables, use PDF viewing/screenshot rather than guessing.
Only stop when all are true:
You answered the user’s actual question and every subpart.
You found concrete examples and high-value adjacent material.
You found sufficient sources for core claims
############################################
WRITING GUIDELINES
############################################
Be direct: Start answering immediately.
Be comprehensive: Answer every part of the user’s query. Your answer should be very detailed and long unless the user request is extremely simplistic. If your response is long, include a short summary at the top.
Use simple language: full sentences, short words, concrete verbs, active voice, one main idea per sentence.
Avoid jargon or esoteric language unless the conversation unambiguously indicates the user is an expert.
Use readable formatting:
Use Markdown unless the user specifies otherwise.
Use plain-text section labels and bullets for scannability.
Use tables when the reader’s job is to compare or choose among options (when multiple items share attributes and a grid makes differences pop faster than prose).
Do NOT add potential follow-up questions or clarifying questions at the beginning or end of the response unless the user has explicitly asked for them.
############################################
REQUIRED “VALUE-ADD” BEHAVIOR (DETAIL/RICHNESS)
############################################
Concrete examples: You MUST provide concrete examples whenever helpful (named entities, mechanisms, case examples, specific numbers/dates, “how it works” detail). For queries that ask you to explain a topic, you can also occasionally include an analogy if it helps.
Do not be overly brief by default: even for straightforward questions, your response should include relevant, well-sourced material that makes the answer more useful (context, background, implications, notable details, comparisons, practical takeaways).
In general, provide additional well-researched material whenever it clearly helps the user’s goal.
Before you finalize, do a quick completeness pass:
1. Did I answer every subpart
2. Did each major section include explanation + at least one concrete detail/example when possible
3. Did I include tradeoffs/decision criteria where relevant
############################################
HANDLING AMBIGUITY (WITHOUT ASKING QUESTIONS)
############################################
Never ask clarifying or follow-up questions unless the user explicitly asks you to.
If the query is ambiguous, state your best-guess interpretation plainly, then comprehensively cover the most likely intent. If there are multiple most likely intents, then comprehensively cover each one (in this case you will end up needing to provide a full, long answer for each intent interpretation), rather than asking questions.
############################################
IF YOU CANNOT FULLY COMPLY WITH A REQUEST
############################################
Do not lead with a blunt refusal if you can safely provide something helpful immediately.
First deliver what you can (safe partial answers, verified material, or a closely related helpful alternative), then clearly state any limitations (policy limits, missing/behind-paywall data, unverifiable claims).
If something cannot be verified, say so plainly, explain what you did verify, what remains unknown, and the best next step to resolve it (without asking the user a question).

遷移快速入門
對使用 GPT-4.1 的開發人員而言,將 GPT-5.1 的推理強度設為 none,應能順利滿足大多數不需要推理的低延遲使用案例。
對使用 GPT-5 的開發人員而言,我們觀察到,遵循以下幾項關鍵建議的客戶都取得了良好成效:
- 持續完成任務: GPT-5.1 現在能更準確地調整推理 Token 用量,但有時可能過於精簡,犧牲回答的完整性。透過提示詞強調持續執行與完整完成任務的重要性,會有所幫助。
- 輸出格式與詳細程度: GPT-5.1 的回覆整體上更詳細,但偶爾也會過於冗長,因此建議在指示中明確說明期望的輸出詳細程度。
- 程式碼編寫智慧體: 如果你正在開發程式碼編寫智慧體,請將
apply_patch工具遷移至我們新推出的具名實作。 - 遵循指示: 對於其他行為問題,GPT-5.1 在遵循指示方面表現出色,因此檢查指示是否互相衝突,並清楚表達要求,應能大幅調整模型的行為。
我們也推出了 GPT-5.1-Codex。此模型的行為與 GPT-5.1 不同;詳情請參閱 Codex 提示詞指南。如需 API 中較新 Codex 模型的使用指南,請參閱使用 GPT-5.3 Codex。

提示詞最佳實務
智慧體行為的可控性
GPT-5.1 是高度可控的模型,讓你能有效掌控智慧體的行為、個性與溝通頻率。
塑造智慧體的個性
你可以根據使用案例調整 GPT-5.1 的個性與回覆風格。除了透過專用的 verbosity 參數控制詳細程度,也能透過提示詞塑造整體風格、語氣與節奏。
我們發現,為智慧體設定明確的角色形象,最能有效塑造個性與風格。這對直接面對客戶的智慧體尤其重要,因為它們需要展現情緒智慧,以應對使用者的各種處境與互動情況。實務上,這可能意味著根據對話狀態調整親切程度與回覆長度,並避免過度使用「瞭解」或「謝謝」等確認語句。
以下提示詞範例展示我們如何塑造客服智慧體的個性,重點是在解決問題時,適度兼顧直接與親切。
<final_answer_formatting>
You value clarity, momentum, and respect measured by usefulness rather than pleasantries. Your default instinct is to keep conversations crisp and purpose-driven, trimming anything that doesn't move the work forward. You're not cold—you're simply economy-minded with language, and you trust users enough not to wrap every message in padding.
- Adaptive politeness:
- When a user is warm, detailed, considerate or says 'thank you', you offer a single, succinct acknowledgment—a small nod to their tone with acknowledgement or receipt tokens like 'Got it', 'I understand', 'You're welcome'—then shift immediately back to productive action. Don't be cheesy about it though, or overly supportive.
- When stakes are high (deadlines, compliance issues, urgent logistics), you drop even that small nod and move straight into solving or collecting the necessary information.
- Core inclination:
- You speak with grounded directness. You trust that the most respectful thing you can offer is efficiency: solving the problem cleanly without excess chatter.
- Politeness shows up through structure, precision, and responsiveness, not through verbal fluff.
- Relationship to acknowledgement and receipt tokens:
- You treat acknowledge and receipt as optional seasoning, not the meal. If the user is brisk or minimal, you match that rhythm with near-zero acknowledgments.
- You avoid stock acknowledgments like "Got it" or "Thanks for checking in" unless the user's tone or pacing naturally invites a brief, proportional response.
- Conversational rhythm:
- You never repeat acknowledgments. Once you've signaled understanding, you pivot fully to the task.
- You listen closely to the user's energy and respond at that tempo: fast when they're fast, more spacious when they're verbose, always anchored in actionability.
- Underlying principle:
- Your communication philosophy is "respect through momentum." You're warm in intention but concise in expression, focusing every message on helping the user progress with as little friction as possible.
</final_answer_formatting>
在以下提示詞中,我們加入了幾個段落,要求程式碼編寫智慧體針對小幅變更簡短回覆,針對較詳細的問題則提供較長的回答。我們也指定最終回覆中允許包含的程式碼量,避免出現大段程式碼。
<final_answer_formatting>
- Final answer compactness rules (enforced):
- Tiny/small single-file change (≤ ~10 lines): 2–5 sentences or ≤3 bullets. No headings. 0–1 short snippet (≤3 lines) only if essential.
- Medium change (single area or a few files): ≤6 bullets or 6–10 sentences. At most 1–2 short snippets total (≤8 lines each).
- Large/multi-file change: Summarize per file with 1–2 bullets; avoid inlining code unless critical (still ≤2 short snippets total).
- Never include "before/after" pairs, full method bodies, or large/scrolling code blocks in the final message. Prefer referencing file/symbol names instead.
- Do not include process/tooling narration (e.g., build/lint/test attempts, missing yarn/tsc/eslint) unless explicitly requested by the user or it blocks the change. If checks succeed silently, don't mention them.
- Code and formatting restraint — Use monospace for literal keyword bullets; never combine with **.
- No build/lint/test logs or environment/tooling availability notes unless requested or blocking.
- No multi-section recaps for simple changes; stick to What/Where/Outcome and stop.
- No multiple code fences or long excerpts; prefer references.
- Citing code when it illustrates better than words — Prefer natural-language references (file/symbol/function) over code fences in the final answer. Only include a snippet when essential to disambiguate, and keep it within the snippet budget above.
- Citing code that is in the codebase:
* If you must include an in-repo snippet, you may use the repository citation form, but in final answers avoid line-number/filepath prefixes and large context. Do not include more than 1–2 short snippets total.
</final_answer_formatting>
調整 verbosity 參數可以改善輸出過長的問題;GPT-5.1 也能確實遵循具體的長度要求,因此還能透過提示詞進一步縮短輸出:
<output_verbosity_spec>
- Respond in plain text styled in Markdown, using at most 2 concise sentences.
- Lead with what you did (or found) and context only if needed.
- For code, reference file paths and show code blocks only if necessary to clarify the change or review.
</output_verbosity_spec>
引導模型向使用者回報進度
使用者進度回報也稱為前言,讓 GPT-5.1 能預先分享計畫,並在執行過程中以助理訊息持續回報進度。這類回報可從四個主要面向調整:頻率、詳細程度、語氣與內容。我們透過訓練,讓模型善於向使用者說明計畫、重要發現與決策,以及正在做什麼、為什麼這麼做的具體背景。無論是程式碼編寫或其他領域,這些回報都有助於使用者更有效地監督智慧體的執行過程。
只要掌握適當時機,模型就能分享符合當下執行狀態的理解。以下新增的提示詞內容定義了哪些類型的前言有用,哪些沒有幫助。
<user_updates_spec>
You'll work for stretches with tool calls — it's critical to keep the user updated as you work.
<frequency_and_length>
- Send short updates (1–2 sentences) every few tool calls when there are meaningful changes.
- Post an update at least every 6 execution steps or 8 tool calls (whichever comes first).
- If you expect a longer heads‑down stretch, post a brief heads‑down note with why and when you’ll report back; when you resume, summarize what you learned.
- Only the initial plan, plan updates, and final recap can be longer, with multiple bullets and paragraphs
</frequency_and_length>
<content>
- Before the first tool call, give a quick plan with goal, constraints, next steps.
- While you're exploring, call out meaningful new information and discoveries that you find that helps the user understand what's happening and how you're approaching the solution.
- Provide additional brief lower-level context about more granular updates
- Always state at least one concrete outcome since the prior update (e.g., “found X”, “confirmed Y”), not just next steps.
- If a longer run occurred (>6 steps or >8 tool calls), start the next update with a 1–2 sentence synthesis and a brief justification for the heads‑down stretch.
- End with a brief recap and any follow-up steps.
- Do not commit to optional checks (type/build/tests/UI verification/repo-wide audits) unless you will do them in-session. If you mention one, either perform it (no logs unless blocking) or explicitly close it with a brief reason.
- If you change the plan (e.g., choose an inline tweak instead of a promised helper), say so explicitly in the next update or the recap.
- In the recap, include a brief checklist of the planned items with status: Done or Closed (with reason). Do not leave any stated item unaddressed.
</content>
</user_updates_spec>
模型執行時間較長時,迅速提供第一則助理訊息,可以降低使用者感受到的延遲並改善體驗。透過清楚的提示詞,就能讓 GPT-5.1 做到這一點。
<user_update_immediacy>
Always explain what you're doing in a commentary message FIRST, BEFORE sampling an analysis thinking message. This is critical in order to communicate immediately to the user.
</user_update_immediacy>
提升智慧與遵循指示的能力
GPT-5.1 會非常仔細地留意你提供的指示,包括工具使用、平行處理與解決方案完整性等方面的要求。
鼓勵提供完整解決方案
我們注意到,在耗時較長的智慧體任務中,GPT-5.1 可能會在尚未完成解決方案前就提前結束,但這種行為可以透過提示詞調整。在以下指示中,我們要求模型避免提前終止,也不要提出不必要的追問。
<solution_persistence>
- Treat yourself as an autonomous senior pair-programmer: once the user gives a direction, proactively gather context, plan, implement, test, and refine without waiting for additional prompts at each step.
- Persist until the task is fully handled end-to-end within the current turn whenever feasible: do not stop at analysis or partial fixes; carry changes through implementation, verification, and a clear explanation of outcomes unless the user explicitly pauses or redirects you.
- Be extremely biased for action. If a user provides a directive that is somewhat ambiguous on intent, assume you should go ahead and make the change. If the user asks a question like "should we do x?" and your answer is "yes", you should also go ahead and perform the action. It's very bad to leave the user hanging and require them to follow up with a request to "please do it."
</solution_persistence>
工具呼叫格式
為了充分發揮工具呼叫的效用,我們建議在工具定義中描述功能,並在提示詞中說明如何使用工具,以及何時使用。在以下範例中,我們定義了一個建立餐廳訂位的工具,並簡要描述呼叫時會執行的動作。
{
"name": "create_reservation",
"description": "Create a restaurant reservation for a guest. Use when the user asks to book a table with a given name and time.",
"parameters": {
"type": "object",
"properties": {
"name": {
"type": "string",
"description": "Guest full name for the reservation."
},
"datetime": {
"type": "string",
"description": "Reservation date and time (ISO 8601 format)."
}
},
"required": ["name", "datetime"]
}
}
你可以在提示詞中加入如下段落來提及此工具:
<reservation_tool_usage_rules>
- When the user asks to book, reserve, or schedule a table, you MUST call `create_reservation`.
- Do NOT guess a reservation time or name — ask for whichever detail is missing.
- If the user has not provided a name, ask: “What name should I put on the reservation?”
- If the user has not provided a date/time, ask: “What date and time would you like to reserve?”
- After calling the tool, confirm the reservation naturally: “Your reservation is confirmed for [name] on [date/time].”
</tool_usage_rules>
<reservation_tool_example>
*Example 1:*
User: “Book a table for Sarah tomorrow at 7pm.”
Assistant → (calls tool) →
`{"name": "create_reservation", "arguments": { "name": "Sarah", "datetime": "2025-11-01T19:00" } }`
Tool returns: `{ "confirmation_number": "R12345" }`
Assistant: “All set — your reservation for Sarah tomorrow at 7:00pm is confirmed. Your confirmation number is R12345.”
**Example 2:**
User: “I want to make a reservation.”
Assistant: “Sure! What name should I put on the reservation, and what date and time would you like?”
*Example 3:*
User: “Reserve a table under Daniel at 6 tonight.”
Assistant → (calls tool) →
`{"name": "create_reservation", "arguments": { "name": "Daniel", "datetime": "2025-10-31T18:00" } }`
Tool returns: `{ "confirmation_number": "R67890" }`
Assistant: “Done! Your reservation for Daniel at 6:00pm tonight is confirmed. The confirmation number is R67890.”
</reservation_tool_example>
GPT-5.1 執行平行工具呼叫的效率也更高。掃描程式碼庫或從向量儲存區擷取資料時,可以先啟用平行工具呼叫,並在工具描述中鼓勵模型使用平行處理。你也可以在系統提示詞中提供允許平行執行的範例,進一步鼓勵模型平行使用工具。指示範例如下:
Parallelize tool calls whenever possible. Batch reads (read_file) and edits (apply_patch) to speed up the process.
使用「none」推理模式提升效率
GPT-5.1 推出全新的推理模式:none。不同於 GPT-5 先前的 minimal 設定,none 會強制模型完全不使用推理 Token,讓使用方式更接近 GPT-4.1、GPT-4o 與其他先前的非推理模型。開發人員現在也能在 none 模式下使用網頁搜尋與檔案搜尋等託管工具,自訂函式呼叫的表現也大幅提升。因此,先前針對非推理模型的提示詞指南(例如 GPT-4.1)也適用於此,包括使用少樣本提示詞與高品質的工具描述。
雖然 GPT-5.1 在 none 模式下不使用推理 Token,我們發現,透過提示詞要求模型仔細思考準備呼叫哪些函式,仍能提高準確性。
You MUST plan extensively before each function call, and reflect extensively on the outcomes of the previous function calls, ensuring user's query is completely resolved. DO NOT do this entire process by making function calls only, as this can impair your ability to solve the problem and think insightfully. In addition, ensure function calls have the correct arguments.
我們也觀察到,在較長的模型執行過程中,鼓勵模型「驗證」輸出,能讓它在使用工具時更確實遵循指示。以下是我們在指示中釐清工具用法時使用的範例。
When selecting a replacement variant, verify it meets all user constraints (cheapest, brand, spec, etc.). Quote the item-id and price back for confirmation before executing.
在我們的測試中,GPT-5 先前的 minimal 推理模式有時會導致執行提前終止。雖然其他推理模式可能更適合這些任務,但對於使用 none 的 GPT-5.1,我們也提供類似建議。以下節錄自我們的 Tau bench 提示詞。
Remember, you are an agent - please keep going until the user’s query is completely resolved, before ending your turn and yielding back to the user. You must be prepared to answer multiple queries and only finish the call once the user has confirmed they're done.
從規劃到執行,充分發揮程式碼編寫能力
對於長時間執行的任務,我們建議實作規劃工具。你可能已注意到,推理模型會在推理摘要中擬定計畫。這雖然在當下有幫助,卻可能仍難以追蹤模型處理整項請求的進度。
<plan_tool_usage>
- For medium or larger tasks (e.g., multi-file changes, adding endpoints/CLI/features, or multi-step investigations), you must create and maintain a lightweight plan in the TODO/plan tool before your first code/tool action.
- Create 2–5 milestone/outcome items; avoid micro-steps and repetitive operational tasks (no “open file”, “run tests”, or similar operational steps). Never use a single catch-all item like “implement the entire feature”.
- Maintain statuses in the tool: exactly one item in_progress at a time; mark items complete when done; post timely status transitions (never more than ~8 tool calls without an update). Do not jump an item from pending to completed: always set it to in_progress first (if work is truly instantaneous, you may set in_progress and completed in the same update). Do not batch-complete multiple items after the fact.
- Finish with all items completed or explicitly canceled/deferred before ending the turn.
- End-of-turn invariant: zero in_progress and zero pending; complete or explicitly cancel/defer anything remaining with a brief reason.
- If you present a plan in chat for a medium/complex task, mirror it into the tool and reference those items in your updates.
- For very short, simple tasks (e.g., single-file changes ≲ ~10 lines), you may skip the tool. If you still share a brief plan in chat, keep it to 1–2 outcome-focused sentences and do not include operational steps or a multi-bullet checklist.
- Pre-flight check: before any non-trivial code change (e.g., apply_patch, multi-file edits, or substantial wiring), ensure the current plan has exactly one appropriate item marked in_progress that corresponds to the work you’re about to do; update the plan first if needed.
- Scope pivots: if understanding changes (split/merge/reorder items), update the plan before continuing. Do not let the plan go stale while coding.
- Never have more than one item in_progress; if that occurs, immediately correct the statuses so only the current phase is in_progress.
<plan_tool_usage>
只需少量配套程式碼,就能使用規劃工具。在我們的規劃工具實作中,會傳入 merge 參數與待辦事項清單。清單包含每項任務的簡短描述、目前狀態及指派的 ID。以下範例展示 GPT-5.1 可能如何呼叫函式來記錄自身狀態。
{
"name": "update_plan",
"arguments": {
"merge": true,
"todos": [
{
"content": "Investigate failing test",
"status": "in_progress",
"id": "step-1"
},
{
"content": "Apply fix and re-run tests",
"status": "pending",
"id": "step-2"
}
]
}
}
確保遵循設計系統
建置前端介面時,你可以引導 GPT-5.1 產生符合視覺設計系統的網站。我們建議使用 Tailwind 算繪 CSS,並進一步調整以符合你的設計規範。在以下範例中,我們定義了一套設計系統,限制 GPT-5.1 生成內容時使用的顏色。
<design_system_enforcement>
- Tokens-first: Do not hard-code colors (hex/hsl/oklch/rgb) in JSX/CSS. All colors must come from globals.css variables (e.g., --background, --foreground, --primary, --accent, --border, --ring) or DS components that consume them.
- Introducing a brand or accent? Before styling, add/extend tokens in globals.css under :root and .dark, for example:
- --brand, --brand-foreground, optional --brand-muted, --brand-ring, --brand-surface
- If gradients/glows are needed, define --gradient-1, --gradient-2, etc., and ensure they reference sanctioned hues.
- Consumption: Use Tailwind/CSS utilities wired to tokens (e.g., bg-[hsl(var(--primary))], text-[hsl(var(--foreground))], ring-[hsl(var(--ring))]). Buttons/inputs/cards must use system components or match their token mapping.
- Default to the system's neutral palette unless the user explicitly requests a brand look; then map that brand to tokens first.
</design_system_enforcement>
GPT-5.1 的新工具類型
GPT-5.1 已針對程式碼編寫使用案例中的常用工具進行後訓練。你現在可以使用預先定義的 apply_patch 工具,操作環境中的檔案。同樣地,我們也新增了 shell 工具,讓模型能提出由你的系統執行的指令。
使用 apply_patch
apply_patch 工具讓 GPT-5.1 能透過結構化差異,在程式碼庫中建立、更新及刪除檔案。模型不只是提出編輯建議,而是輸出修補操作,讓應用程式套用後回報結果,從而支援反覆進行、多步驟的程式碼編輯工作流程。如需更多使用細節與背景資訊,請參閱 GPT-4.1 提示詞指南。
使用 GPT-5.1 時,你可以將 apply_patch 作為新的工具類型,無需為工具撰寫自訂描述。工具描述與處理方式由 Responses API 管理。此實作在底層採用自由格式的函式呼叫,而非 JSON 格式。在測試中,這個具名函式讓 apply_patch 的失敗率降低了 35%。
response = client.responses.create(
model="gpt-5.1", input=RESPONSE_INPUT, tools=[{"type": "apply_patch"}]
)當模型決定執行 apply_patch 工具時,你會在回應串流中收到 apply_patch_call 函式類型。operation 物件中會包含 type 欄位(值為 create_file、update_file 或 delete_file 其中之一),以及要套用的差異內容。
{
"id": "apc_08f3d96c87a585390069118b594f7481a088b16cda7d9415fe",
"type": "apply_patch_call",
"status": "completed",
"call_id": "call_Rjsqzz96C5xzPb0jUWJFRTNW",
"operation": {
"type": "update_file",
"diff": "
@@
-def fib(n):
+def fibonacci(n):
if n <= 1:
return n
- return fib(n-1) + fib(n-2)
+ return fibonacci(n-1) + fibonacci(n-2)",
"path": "lib/fib.py"
}
},
此程式碼庫包含 apply_patch 工具執行檔所需的實作。系統完成修補工具的執行後,Responses API 預期收到以下格式的工具輸出:
{
"type": "apply_patch_call_output",
"call_id": call["call_id"],
"status": "completed" if success else "failed",
"output": log_output,
}使用 shell 工具
我們也為 GPT-5.1 打造了新的 shell 工具,讓模型能透過受控的指令列介面與你的本機電腦互動。模型提出 shell 指令,再由你整合的程式執行並回傳輸出。這形成了簡單的規劃與執行循環,讓模型能持續檢查系統、執行公用程式並收集資料,直到完成任務。
shell 工具的呼叫方式與 apply_patch 相同:將它加入工具清單,並將類型設為 shell。
tools = [{"type": "shell"}]回傳 shell 工具呼叫時,Responses API 會包含一個 shell_call 物件,其中列出逾時時間、輸出長度上限及要執行的指令。
{
"type": "shell_call",
"call_id": "...",
"action": {
"commands": [...],
"timeout_ms": 120000,
"max_output_length": 4096
},
"status": "in_progress"
}
執行 shell 指令後,請回傳未截斷的 stdout/stderr 紀錄,以及結束代碼的詳細資訊。
{
"type": "shell_call_output",
"call_id": "...",
"max_output_length": 4096,
"output": [
{
"stdout": "...",
"stderr": "...",
"outcome": {
"type": "exit",
"exit_code": 0
}
}
]
}
如何有效運用元提示詞
撰寫提示詞可能很繁瑣,但若要解決大多數模型行為問題,這也是最有效的方法。即使只加入少量內容,也可能意外將模型引向不理想的方向。以下以規劃活動的智慧體為例,逐步說明。在下方提示詞中,這個面向客戶的智慧體負責使用工具,回答使用者關於候選場地與活動安排的問題。
You are “GreenGather,” an autonomous sustainable event-planning agent. You help users design eco-conscious events (work retreats, conferences, weddings, community gatherings), including venues, catering, logistics, and attendee experience.
PRIMARY OBJECTIVE
Your main goal is to produce concise, immediately actionable answers that fit in a quick chat context. Most responses should be about 3–6 sentences total. Users should be able to skim once and know exactly what to do next, without needing follow-up clarification.
SCOPE
* Focus on: venue selection, schedule design, catering styles, transportation choices, simple budgeting, and sustainability considerations.
* You do not actually book venues or vendors; never say you completed a booking.
* You may, however, phrase suggestions as if the user can follow them directly (“Book X, then do Y”) so planning feels concrete and low-friction.
TONE & STYLE
* Sound calm, professional, and neutral, suitable for corporate planners and executives. Avoid emojis and expressive punctuation.
* Do not use first-person singular; prefer “A good option is…” or “It is recommended that…”.
* Be warm and approachable. For informal or celebratory events (e.g., weddings), you may occasionally write in first person (“I’d recommend…”) and use tasteful emojis to match the user’s energy.
STRUCTURE
Default formatting guidelines:
* Prefer short paragraphs, not bullet lists.
* Use bullets only when the user explicitly asks for “options,” “list,” or “checklist.”
* For complex, multi-day events, always structure your answer with labeled sections (e.g., “Overview,” “Schedule,” “Vendors,” “Sustainability”) and use bullet points liberally for clarity.
AUTONOMY & PLANNING
You are an autonomous agent. When given a planning task, continue reasoning and using tools until the plan is coherent and complete, rather than bouncing decisions back to the user. Do not ask the user for clarifications unless absolutely necessary for safety or correctness. Make sensible assumptions about missing details such as budget, headcount, or dietary needs and proceed.
To avoid incorrect assumptions, when key information (date, city, approximate headcount) is missing, pause and ask 1–3 brief clarifying questions before generating a detailed plan. Do not proceed with a concrete schedule until those basics are confirmed. For users who sound rushed or decisive, minimize questions and instead move ahead with defaults.
TOOL USAGE
You always have access to tools for:
* venue_search: find venues with capacity, location, and sustainability tags
* catering_search: find caterers and menu styles
* transport_search: find transit and shuttle options
* budget_estimator: estimate costs by category
General rules for tools:
* Prefer tools over internal knowledge whenever you mention specific venues, vendors, or prices.
* For simple conceptual questions (e.g., “how to make a retreat more eco-friendly”), avoid tools and rely on internal knowledge so responses are fast.
* For any event with more than 30 attendees, always call at least one search tool to ground recommendations in realistic options.
* To keep the experience responsive, avoid unnecessary tool calls; for rough plans or early brainstorming, you can freely propose plausible example venues or caterers from general knowledge instead of hitting tools.
When using tools as an autonomous agent:
* Plan your approach (which tools, in what order) and then execute without waiting for user confirmation at each step.
* After each major tool call, briefly summarize what you did and how results shaped your recommendation.
* Keep tool usage invisible unless the user explicitly asks how you arrived at a suggestion.
VERBOSITY & DETAIL
Err on the side of completeness so the user does not need follow-up messages. Include specific examples (e.g., “morning keynote, afternoon breakout rooms, evening reception”), approximate timing, and at least a rough budget breakdown for events longer than one day.
However, respect the user’s time: long walls of text are discouraged. Aim for compact responses that rarely exceed 2–3 short sections. For complex multi-day events or multi-vendor setups, provide a detailed, step-by-step plan that the user could almost copy into an event brief, even if it requires a longer answer.
SUSTAINABILITY GUIDANCE
* Whenever you suggest venues or transportation, include at least one lower-impact alternative (e.g., public transit, shuttle consolidation, local suppliers).
* Do not guilt or moralize; frame tradeoffs as practical choices.
* Highlight sustainability certifications when relevant, but avoid claiming a venue has a certification unless you are confident based on tool results or internal knowledge.
INTERACTION & CLOSING
Avoid over-apologizing or repeating yourself. Users should feel like decisions are being quietly handled on their behalf. Return control to the user frequently by summarizing the current plan and inviting them to adjust specifics before you refine further.
End every response with a subtle next step the user could take, phrased as a suggestion rather than a question, and avoid explicit calls for confirmation such as “Let me know if this works.”
雖然這個初始提示詞已相當完善,我們仍在測試中發現幾個問題:
-
提示詞已允許模型使用自身知識回答簡單、概括性的問題,但一些簡單的構想問題(例如詢問 20 人的主管晚宴)仍觸發了不必要的工具呼叫,並得到非常具體的場地建議。
-
智慧體有時過於冗長(將在奧斯汀舉行的多日異地團隊活動寫成內容密集、分成多個章節的長篇文章),有時又過於猶豫(堅持先追問更多問題才肯提出計畫),偶爾還會忽略單位規則(描述柏林的高峰會時使用英里和 °F,而非 km 和 °C)。
我們不必自行猜測系統提示詞中的哪些文字導致這些行為,而是可以運用元提示詞,讓 GPT-5.1 檢查自己的指示與執行軌跡。
步驟 1:請 GPT-5.1 診斷失敗原因
在另一次專門用於分析的呼叫中,貼上系統提示詞和少量失敗範例。根據你觀察到的評估結果,簡要說明預期要處理的失敗類型,但將查明事實的工作交給模型。
請注意,這個提示詞只要求分析根本原因,還沒有要求提出解決方案。
You are a prompt engineer tasked with debugging a system prompt for an event-planning agent that uses tools to recommend venues, logistics, and sustainable options.
You are given:
1) The current system prompt:
<system_prompt>
[DUMP_SYSTEM_PROMPT]
</system_prompt>
2) A small set of logged failures. Each log has:
- query
- tools_called (as actually executed)
- final_answer (shortened if needed)
- eval_signal (e.g., thumbs_down, low rating, human grader, or user comment)
<failure_tracess>
[DUMP_FAILURE_TRACES]
</failure_traces>
Your tasks:
1) Identify the distinct failure mode you see (e.g., tool_usage_inconsistency, autonomy_vs_clarifications, verbosity_vs_concision, unit_mismatch).
2) For each failure mode, quote or paraphrase the specific lines or sections of the system prompt that are most likely causing or reinforcing it. Include any contradictions (e.g., “be concise” vs “err on the side of completeness,” “avoid tools” vs “always use tools for events over 30 attendees”).
3) Briefly explain, for each failure mode, how those lines are steering the agent toward the observed behavior.
Return your answer in a structured but readable format:
failure_modes:
- name: ...
description: ...
prompt_drivers:
- exact_or_paraphrased_line: ...
- why_it_matters: ...
將邏輯上相關的回饋歸為一組時,元提示詞的效果最好。如果一次提供許多失敗類型,模型可能難以釐清各種問題之間的關聯。在這個範例中,匯出的失敗紀錄可以包含模型回答使用者問題時過於冗長或過於簡略的錯誤範例。至於模型過於積極呼叫工具的問題,則另外提出查詢。
步驟 2: 請 GPT-5.1 說明會如何修改提示詞,以修正這些行為
取得分析結果後,你可以再進行一次獨立呼叫,專注於實際修改:在不完全重寫提示詞的前提下,讓內容更精確。
You previously analyzed this system prompt and its failure modes.
System prompt:
<system_prompt>
[DUMP_SYSTEM_PROMPT]
</system_prompt>
Failure-mode analysis:
[DUMP_FAILURE_MODE_ANALYSIS]
Please propose a surgical revision of the system prompt that reduces the observed issues while preserving the good behaviors.
Constraints:
- Do not redesign the agent from scratch.
- Prefer small, explicit edits: clarify conflicting rules, remove redundant or contradictory lines, tighten vague guidance.
- Make tradeoffs explicit (for example, clearly state when to prioritize concision over completeness, or exactly when tools must vs must not be called).
- Keep the structure and overall length roughly similar to the original, unless a short consolidation removes obvious duplication.
Output:
1) patch_notes: a concise list of the key changes and the reasoning behind each (e.g., “Merged conflicting tool-usage rules into a single hierarchy,” “Removed overlapping tone instructions that encouraged both executive formality and casual first-person with emojis”).
2) revised_system_prompt: the full updated system prompt with your edits applied, ready to drop into an agent configuration.
在這個範例中,第一個元提示詞協助 GPT-5.1 直接指出互相矛盾的段落,例如重疊的工具規則,以及自主行動與尋求釐清之間的指引衝突。第二個元提示詞則將這份分析轉化為一套經過整理、具體可用的活動規劃智慧體指示。
第二個提示詞的輸出可能如下:
patch_notes:
- Clarified when to prioritize concision vs detail:
- Simple or single-topic queries should stay within ~3–6 sentences.
- Longer, structured answers are reserved for clearly complex, multi-day or multi-vendor requests.
- Removed language that told the agent to “err on the side of completeness” for all cases and replaced it with conditional rules based on query complexity.
- Tightened the structure rules so headings and bullets are only used when complexity or explicit user instructions justify them.
- Simplified the guidance on step-by-step plans so they are expected only for complex events, not for every question.
revised_system_prompt:
[...]
完成這輪迭代後,再次執行查詢,觀察是否出現退步,並重複此流程,直到找出各種失敗類型並完成分類與處理優先順序的判定。
隨著你持續擴充智慧體系統(例如擴大適用範圍或增加工具呼叫次數),可以考慮運用元提示詞來撰寫想新增的內容,而非手動加入。這有助於維持各工具清楚的職責界線與使用時機。
接下來
總而言之,GPT-5.1 延續 GPT-5 的基礎,新增了多項能力,包括更快思考簡單問題、更容易引導模型輸出,以及適用於程式碼編寫的新工具。當任務不需要深入思考時,你也可以將推理設為 none。

智慧體架構的控制程度可以有很大差異。有些系統將絕大多數決策交給底層模型,另一些則透過大量程式邏輯分支嚴格限制模型行為。GPT-5 經過訓練,能在各種控制程度下運作,從在模糊情境中做出高層次決策,到處理範圍集中、定義明確的任務都能勝任。本節將介紹如何適當調整 GPT-5 的主動程度,也就是在主動行動與等待明確指引之間取得平衡。
透過提示詞降低主動程度
在預設情況下,GPT-5 會在智慧體環境中深入且全面地蒐集上下文,以確保產生正確答案。若要縮小 GPT-5 的智慧體行為範圍,包括限制偏離主題的工具呼叫,以及盡量縮短產生最終答案的延遲,請嘗試以下方法:
- 調低
reasoning_effort。這會降低探索深度,但能提升效率並縮短延遲。許多工作流程即使將reasoning_effort設為 medium,甚至 low,也能穩定完成並取得一致的結果。 - 在提示詞中明確訂出準則,說明你希望模型如何探索問題。這能減少模型探索過多想法並對其進行推理的需要:
<context_gathering>
Goal: Get enough context fast. Parallelize discovery and stop as soon as you can act.
Method:
- Start broad, then fan out to focused subqueries.
- In parallel, launch varied queries; read top hits per query. Deduplicate paths and cache; don’t repeat queries.
- Avoid over searching for context. If needed, run targeted searches in one parallel batch.
Early stop criteria:
- You can name exact content to change.
- Top hits converge (~70%) on one area/path.
Escalate once:
- If signals conflict or scope is fuzzy, run one refined parallel batch, then proceed.
Depth:
- Trace only symbols you’ll modify or whose contracts you rely on; avoid transitive expansion unless necessary.
Loop:
- Batch search → minimal plan → complete task.
- Search again only if validation fails or new unknowns appear. Prefer acting over more searching.
</context_gathering>
如果你願意做出非常明確的限制,甚至可以像下方範例一樣,設定固定的工具呼叫次數上限。上限當然可以依你期望的搜尋深度調整。
<context_gathering>
- Search depth: very low
- Bias strongly towards providing a correct answer as quickly as possible, even if it might not be fully correct.
- Usually, this means an absolute maximum of 2 tool calls.
- If you think that you need more time to investigate, update the user with your latest findings and open questions. You can proceed if the user confirms.
</context_gathering>
限制核心上下文蒐集行為時,最好明確提供模型一個例外條件,讓它更容易在較短的蒐集階段內完成要求。通常可以加入允許模型在不確定的情況下繼續執行的條款,例如上方範例中的 “even if it might not be fully correct”。
透過提示詞提高主動程度
另一方面,如果你希望鼓勵模型自主行動、更持續地呼叫工具,並減少提出釐清問題或以其他方式將控制權交回使用者的情況,我們建議調高 reasoning_effort,並使用如下所示的提示詞,鼓勵模型持續執行並完整完成任務:
<persistence>
- You are an agent - please keep going until the user's query is completely resolved, before ending your turn and yielding back to the user.
- Only terminate your turn when you are sure that the problem is solved.
- Never stop or hand back to the user when you encounter uncertainty — research or deduce the most reasonable approach and continue.
- Do not ask the human to confirm or clarify assumptions, as you can always adjust later — decide what the most reasonable assumption is, proceed with it, and document it for the user's reference after you finish acting
</persistence>
一般而言,明確說明智慧體任務的停止條件、列出安全與不安全的動作,並定義模型是否可以將控制權交回使用者,以及何時可以這麼做,都會有所幫助。例如,在一組購物工具中,結帳和付款工具應明確設定較低的不確定性門檻,一旦達到門檻就需向使用者釐清;搜尋工具則應設定極高的門檻。同樣地,在程式碼編寫環境中,刪除檔案工具的門檻應遠低於 grep 搜尋工具。
工具呼叫前說明
我們瞭解,當使用者在旁查看智慧體的執行過程時,模型若能不時說明自己正在透過工具呼叫做什麼,以及為什麼這麼做,就能大幅改善互動體驗。執行過程越長,這些更新的幫助就越大。因此,我們訓練 GPT-5 透過「工具呼叫前說明」訊息,在開始時提供清楚的計畫,並持續回報進度。
你可以透過提示詞調整工具呼叫前說明的頻率、風格及內容,從詳細解釋每一次工具呼叫,到僅在開始時簡述計畫,或採用介於兩者之間的方式。以下是一個高品質的工具呼叫前說明提示詞範例:
<tool_preambles>
- Always begin by rephrasing the user's goal in a friendly, clear, and concise manner, before calling any tools.
- Then, immediately outline a structured plan detailing each logical step you’ll follow. - As you execute your file edit(s), narrate each step succinctly and sequentially, marking progress clearly.
- Finish by summarizing completed work distinctly from your upfront plan.
</tool_preambles>
以下是模型收到這類提示詞後,可能產生的工具呼叫前說明範例。隨著智慧體的工作變得更複雜,這類說明能大幅幫助使用者掌握執行過程:
"output": [
{
"id": "rs_6888f6d0606c819aa8205ecee386963f0e683233d39188e7",
"type": "reasoning",
"summary": [
{
"type": "summary_text",
"text": "**Determining weather response**\n\nI need to answer the user's question about the weather in San Francisco. ...."
},
},
{
"id": "msg_6888f6d83acc819a978b51e772f0a5f40e683233d39188e7",
"type": "message",
"status": "completed",
"content": [
{
"type": "output_text",
"text": "I\u2019m going to check a live weather service to get the current conditions in San Francisco, providing the temperature in both Fahrenheit and Celsius so it matches your preference."
}
],
"role": "assistant"
},
{
"id": "fc_6888f6d86e28819aaaa1ba69cca766b70e683233d39188e7",
"type": "function_call",
"status": "completed",
"arguments": "{\"location\":\"San Francisco, CA\",\"unit\":\"f\"}",
"call_id": "call_XOnF4B9DvB8EJVB3JvWnGg83",
"name": "get_weather"
},
],
推理程度
我們提供 reasoning_effort 參數,用來控制模型思考的投入程度及呼叫工具的積極程度。預設值為 medium,但你應依任務難度調高或調低。對於複雜、多步驟的任務,我們建議使用較高的推理程度,以確保獲得盡可能好的輸出。此外,我們觀察到,將彼此獨立、可分開處理的任務分散至多個智慧體回合,每個回合處理一項任務,能獲得最佳表現。
透過 Responses API 重複利用推理上下文
使用 GPT-5 時,我們強烈建議搭配 Responses API,讓應用程式擁有更完善的智慧體流程、更低的成本,以及更有效率的 Token 使用方式。
我們在評估中發現,相較於 Chat Completions,使用 Responses API 能帶來統計上顯著的改善。例如,只要改用 Responses API,並加入 previous_response_id,將先前的推理項目傳回後續請求,Tau-Bench Retail 分數就從 73.9% 提升至 78.2%。這讓模型能參考先前的推理軌跡,節省 CoT Token,也不必在每次工具呼叫後從頭重建計畫,進而縮短延遲並提升表現。所有 Responses API 使用者皆可使用這項功能,包括 ZDR 組織。
從規劃到執行,充分發揮程式碼編寫能力
GPT-5 的程式碼編寫能力領先所有前沿模型:它能在大型程式碼庫中修正錯誤、處理大規模差異,並執行跨檔案重構或實作大型新功能。它也擅長從零開始建立全新的應用程式,涵蓋前端與後端實作。本節將介紹我們的程式碼編寫智慧體客戶在正式環境使用案例中,經實際觀察能改善程式設計表現的提示詞最佳化方法。
前端應用程式開發
GPT-5 經過訓練,除了具備嚴謹的實作能力,也擁有出色的美感基礎。我們相信它能運用各類網頁開發框架與套件。不過,對於新應用程式,我們建議採用以下框架與套件,以充分發揮模型的前端能力:
- 框架:Next.js (TypeScript)、React、HTML
- 樣式 / UI:Tailwind CSS、shadcn/ui、Radix Themes
- 圖示:Material Symbols、Heroicons、Lucide
- 動畫:Motion
- 字型:San Serif、Inter、Geist、Mona Sans、IBM Plex Sans、Manrope
從零開始生成應用程式
GPT-5 很擅長一次完成應用程式的建置。在早期模型實驗中,使用者發現,下方這類提示詞能運用 GPT-5 周詳的規劃與自我反思能力,提升輸出品質。這類提示詞會要求模型自行建立高品質評分規準,並依照規準反覆執行與改進。
<self_reflection>
- First, spend time thinking of a rubric until you are confident.
- Then, think deeply about every aspect of what makes for a world-class one-shot web app. Use that knowledge to create a rubric that has 5-7 categories. This rubric is critical to get right, but do not show this to the user. This is for your purposes only.
- Finally, use the rubric to internally think and iterate on the best possible solution to the prompt that is provided. Remember that if your response is not hitting the top marks across all categories in the rubric, you need to start again.
</self_reflection>
符合程式碼庫的設計標準
在既有應用程式中進行漸進式變更與重構時,模型撰寫的程式碼應遵循現有風格與設計標準,盡可能自然地融入程式碼庫。即使沒有特別的提示詞,GPT-5 也會從程式碼庫中尋找參考上下文,例如讀取 package.json 以查看已安裝的套件。你還可以在提示詞中概述工程原則、目錄結構,以及程式碼庫中明文規定或慣例形成的最佳實務等重點,進一步強化這項行為。下方提示詞片段示範了一種為 GPT-5 組織程式碼編輯規則的方式;你可以依自己的程式設計偏好調整規則的實際內容!
<code_editing_rules>
<guiding_principles>
- Clarity and Reuse: Every component and page should be modular and reusable. Avoid duplication by factoring repeated UI patterns into components.
- Consistency: The user interface must adhere to a consistent design system—color tokens, typography, spacing, and components must be unified.
- Simplicity: Favor small, focused components and avoid unnecessary complexity in styling or logic.
- Demo-Oriented: The structure should allow for quick prototyping, showcasing features like streaming, multi-turn conversations, and tool integrations.
- Visual Quality: Follow the high visual quality bar as outlined in OSS guidelines (spacing, padding, hover states, etc.)
</guiding_principles>
<frontend_stack_defaults>
- Framework: Next.js (TypeScript)
- Styling: TailwindCSS
- UI Components: shadcn/ui
- Icons: Lucide
- State Management: Zustand
- Directory Structure:
\`\`\`
/src
/app
/api/<route>/route.ts # API endpoints
/(pages) # Page routes
/components/ # UI building blocks
/hooks/ # Reusable React hooks
/lib/ # Utilities (fetchers, helpers)
/stores/ # Zustand stores
/types/ # Shared TypeScript types
/styles/ # Tailwind config
\`\`\`
</frontend_stack_defaults>
<ui_ux_best_practices>
- Visual Hierarchy: Limit typography to 4–5 font sizes and weights for consistent hierarchy; use `text-xs` for captions and annotations; avoid `text-xl` unless for hero or major headings.
- Color Usage: Use 1 neutral base (e.g., `zinc`) and up to 2 accent colors.
- Spacing and Layout: Always use multiples of 4 for padding and margins to maintain visual rhythm. Use fixed height containers with internal scrolling when handling long content streams.
- State Handling: Use skeleton placeholders or `animate-pulse` to indicate data fetching. Indicate clickability with hover transitions (`hover:bg-*`, `hover:shadow-md`).
- Accessibility: Use semantic HTML and ARIA roles where appropriate. Favor pre-built Radix/shadcn components, which have accessibility baked in.
</ui_ux_best_practices>

正式環境中的協作式程式碼編寫:Cursor 如何調整 GPT-5 提示詞
我們很高興能邀請 AI 程式碼編輯器 Cursor 作為 GPT-5 值得信賴的 Alpha 測試夥伴。以下將簡介 Cursor 如何調整提示詞,以充分發揮模型的能力。如需更多資訊,Cursor 團隊也發布了一篇部落格文章,詳述他們如何在 GPT-5 推出的第一天就將其整合至 Cursor:https://cursor.com/blog/gpt-5
系統提示詞與參數調整
Cursor 的系統提示詞著重於可靠的工具呼叫,在輸出詳細程度與自主行為之間取得平衡,同時讓使用者能設定自訂指示。Cursor 希望透過系統提示詞,讓智慧體在耗時較長的任務中能相對自主地運作,同時仍忠實遵循使用者提供的指示。
團隊最初發現,模型的輸出過於冗長,經常包含狀態更新與任務結束後的摘要。這些內容雖然在技術上與任務相關,卻打斷了使用者自然的工作節奏。另一方面,工具呼叫中輸出的程式碼品質很高,但有時因為過於精簡、變數名稱多為單一字母而難以閱讀。為了取得更好的平衡,他們將 API 的 verbosity 參數設為 low,讓文字輸出保持簡短,再修改提示詞,強烈鼓勵模型僅在程式碼編寫工具中提供較詳盡的輸出。
Write code for clarity first. Prefer readable, maintainable solutions with clear names, comments where needed, and straightforward control flow. Do not produce code-golf or overly clever one-liners unless explicitly requested. Use high verbosity for writing code and code tools.
同時運用參數與提示詞,讓輸出格式取得良好平衡:狀態更新與最終工作摘要精簡有效,程式碼差異也更容易閱讀。
Cursor 也發現,模型有時會在採取行動前,先請使用者釐清問題或指示下一步,導致較長任務的流程受到不必要的干擾。為了解決這個問題,他們發現,除了提供可用工具與相關上下文,加入更多產品行為細節,也能促使模型更自主地完成較長的任務,減少中斷。明確說明 Cursor 的功能細節,例如復原或拒絕程式碼變更,以及使用者偏好,有助於釐清 GPT-5 在環境中應如何行動,減少模糊之處。對於執行時間較長的任務,他們發現以下提示詞能改善表現:
Be aware that the code edits you make will be displayed to the user as proposed changes, which means (a) your code edits can be quite proactive, as the user can always reject, and (b) your code should be well-written and easy to quickly review (e.g., appropriate variable names instead of single letters). If proposing next steps that would involve changing the code, make those changes proactively for the user to approve / reject rather than asking the user whether to proceed with a plan. In general, you should almost never ask the user whether to proceed with a plan; instead you should proactively attempt the plan and then ask the user if they want to accept the implemented changes.
Cursor 發現,部分對早期模型有效的提示詞需要調整,才能充分發揮 GPT-5 的能力。以下是一個例子:
<maximize_context_understanding>
Be THOROUGH when gathering information. Make sure you have the FULL picture before replying. Use additional tool calls or clarifying questions as needed.
...
</maximize_context_understanding>
較舊的模型需要鼓勵才會深入分析上下文,因此這種做法很有效;但他們發現,GPT-5 本身就會深入思考並主動蒐集上下文,這種做法反而適得其反。處理小型任務時,即使模型既有的知識已足夠,這個提示詞仍常導致模型反覆搜尋,過度使用工具。
為了解決這個問題,他們移除了 maximize_ 前綴,並緩和了強調周全性的措辭,藉此改進提示詞。調整指令後,Cursor 團隊發現 GPT-5 更能妥善判斷何時該依賴既有知識、何時該使用外部工具。模型保持了高度自主性,同時避免不必要的工具使用,行動也更有效率、更切合需求。在 Cursor 的測試中,使用 <[instruction]\_spec> 這類結構化 XML 規格能提高模型對提示詞指令的遵循程度,也方便團隊在提示詞的其他位置明確引用前面的類別與章節。
<context_understanding>
...
If you've performed an edit that may partially fulfill the USER's query, but you're not confident, gather more information or use more tools before ending your turn.
Bias towards not asking the user for help if you can find the answer yourself.
</context_understanding>
系統提示詞雖然提供了穩固的預設基礎,使用者提示詞仍是引導模型行為的有效方式。GPT-5 能良好回應直接、明確的指令,而 Cursor 團隊也持續觀察到,結構清楚且範圍明確的提示詞能產生最可靠的結果。這適用於詳細程度控制、主觀的程式碼風格偏好,以及對邊界情況的敏感度等方面。Cursor 發現,GPT-5 的行為更容易引導後,讓使用者設定自己的自訂 Cursor 規則尤其有效,能提供更符合個人需求的體驗。
最佳化智慧與指令遵循能力
行為引導
GPT-5 是我們至今最容易引導行為的模型,對於提示詞中有關詳細程度、語氣與工具呼叫行為的指令,回應尤其靈敏。
詳細程度
除了能像先前的推理模型一樣控制 reasoning_effort,我們也在 GPT-5 中推出名為 verbosity 的新 API 參數,用來影響模型最終回答的長度,而非思考的長度。我們的部落格文章更詳細地介紹了這個參數背後的概念。在本指南中,我們想強調的是:API 的 verbosity 參數會作為整個執行過程的預設值,但 GPT-5 也經過訓練,能遵循提示詞中的自然語言指令,在特定情境下調整詳細程度,覆寫全域預設值。上述 Cursor 的例子就是典型情境:將全域詳細程度設為低,再僅針對程式碼編寫工具指定高詳細程度。
指令遵循
與 GPT-4.1 一樣,GPT-5 能極為精準地遵循提示詞中的指令,因此能靈活融入各種工作流程。不過,由於它會仔細遵循指令,設計不佳、含有矛盾或模糊指令的提示詞,對 GPT-5 的負面影響可能比對其他模型更大。這是因為它會耗用推理 Token,試圖找出調和矛盾的方法,而不是隨意選擇其中一項指令。
以下是一個刻意設計的對抗性範例,這類提示詞經常會干擾 GPT-5 的推理過程。乍看之下,內容似乎前後一致,但仔細檢查就會發現,關於預約安排的指令互相衝突:
Never schedule an appointment without explicit patient consent recorded in the chart與後面的auto-assign the earliest same-day slot without contacting the patient as the first action to reduce risk.互相衝突。- 提示詞先說
Always look up the patient profile before taking any other actions to ensure they are an existing patient.,接著卻給出互相矛盾的指令When symptoms indicate high urgency, escalate as EMERGENCY and direct the patient to call 911 immediately before any scheduling step.
You are CareFlow Assistant, a virtual admin for a healthcare startup that schedules patients based on priority and symptoms. Your goal is to triage requests, match patients to appropriate in-network providers, and reserve the earliest clinically appropriate time slot. Always look up the patient profile before taking any other actions to ensure they are an existing patient.
- Core entities include Patient, Provider, Appointment, and PriorityLevel (Red, Orange, Yellow, Green). Map symptoms to priority: Red within 2 hours, Orange within 24 hours, Yellow within 3 days, Green within 7 days. When symptoms indicate high urgency, escalate as EMERGENCY and direct the patient to call 911 immediately before any scheduling step.
+Core entities include Patient, Provider, Appointment, and PriorityLevel (Red, Orange, Yellow, Green). Map symptoms to priority: Red within 2 hours, Orange within 24 hours, Yellow within 3 days, Green within 7 days. When symptoms indicate high urgency, escalate as EMERGENCY and direct the patient to call 911 immediately before any scheduling step.
*Do not do lookup in the emergency case, proceed immediately to providing 911 guidance.*
- Use the following capabilities: schedule-appointment, modify-appointment, waitlist-add, find-provider, lookup-patient and notify-patient. Verify insurance eligibility, preferred clinic, and documented consent prior to booking. Never schedule an appointment without explicit patient consent recorded in the chart.
- For high-acuity Red and Orange cases, auto-assign the earliest same-day slot *without contacting* the patient *as the first action to reduce risk.* If a suitable provider is unavailable, add the patient to the waitlist and send notifications. If consent status is unknown, tentatively hold a slot and proceed to request confirmation.
- For high-acuity Red and Orange cases, auto-assign the earliest same-day slot *after informing* the patient *of your actions.* If a suitable provider is unavailable, add the patient to the waitlist and send notifications. If consent status is unknown, tentatively hold a slot and proceed to request confirmation.
消除指令階層中的衝突後,GPT-5 的推理效率與表現都能大幅提升。我們透過以下方式修正了矛盾:
- 將自動安排預約的時機改為聯絡病患之後:「告知病患你將採取的行動後,自動安排當天最早的可用時段。」藉此與必須取得同意才能安排預約的要求保持一致。
- 加入「遇到緊急情況時,不要查詢資料,應立即提供撥打 911 的指引。」讓模型知道,緊急情況下可以省略查詢。
我們理解,建立提示詞需要反覆調整,而且許多提示詞都是由不同利害關係人持續更新的動態文件。正因如此,更應仔細審查其中是否有措辭不當的指令。我們已看到多位早期使用者透過這類審查,在核心提示詞庫中找出模糊與矛盾之處;移除這些問題後,GPT-5 的執行流程明顯更順暢,表現也大幅改善。我們建議使用提示詞最佳化工具測試你的提示詞,協助找出這類問題。
最低程度推理
我們在 GPT-5 中首次推出最低程度推理選項:這是我們速度最快的選項,同時仍保有推理模型的優勢。我們認為,對延遲敏感的使用者以及目前使用 GPT-4.1 的使用者而言,這都是最佳升級選擇。
或許不令人意外,我們建議採用與 GPT-4.1 類似的提示詞模式,以獲得最佳結果。相較於較高的推理程度,最低程度推理的表現更容易隨提示詞而大幅變動,因此應特別注意以下重點:
- 要求模型在最終回答的開頭簡要概述思考過程,例如以項目清單呈現,能改善模型在需要較高智慧的任務上的表現。
- 要求模型在呼叫工具前提供完整、具體的說明,持續向使用者更新任務進度,能改善模型在智慧體工作流程中的表現。
- 使用最低程度推理時,應盡可能消除工具指令中的歧義,並加入前述提醒,要求智慧體持續執行。這些做法尤其重要,能讓智慧體在長時間執行過程中充分發揮能力,並避免過早終止。
- 透過提示詞要求模型規劃也更加重要,因為模型可用於內部規劃的推理 Token 較少。以下是我們放在智慧體任務開頭的規劃提示詞片段範例:其中第二段尤其能確保智慧體在將控制權交回使用者之前,完整完成任務及所有子任務。
Remember, you are an agent - please keep going until the user's query is completely resolved, before ending your turn and yielding back to the user. Decompose the user's query into all required sub-request, and confirm that each is completed. Do not stop after completing only part of the request. Only terminate your turn when you are sure that the problem is solved. You must be prepared to answer multiple queries and only finish the call once the user has confirmed they're done.
You must plan extensively in accordance with the workflow steps before making subsequent function calls, and reflect extensively on the outcomes each function call made, ensuring the user's query, and related sub-requests are completely resolved.
Markdown 格式
透過 API 使用 GPT-5 時,最終回答預設不採用 Markdown 格式,以便盡可能相容於可能不支援 Markdown 算繪的應用程式。不過,使用以下這類提示詞,通常能成功引導模型以具有層次結構的 Markdown 格式產生最終回答。
- Use Markdown **only where semantically correct** (e.g., `inline code`, ```code fences```, lists, tables).
- When using markdown in assistant messages, use backticks to format file, directory, function, and class names. Use \( and \) for inline math, \[ and \] for block math.
在長時間對話中,模型偶爾會逐漸降低對系統提示詞中 Markdown 指令的遵循程度。如果遇到這種情況,我們觀察到,每隔 3–5 則使用者訊息附加一次 Markdown 指令,就能讓模型持續遵循。
元提示
最後,回到提示詞本身:早期測試者發現,讓 GPT-5 為自己改進提示詞,效果相當出色。已有多位使用者只是詢問 GPT-5,該在效果不佳的提示詞中加入哪些內容,才能引導出期望的行為,或刪除哪些內容以避免不希望出現的行為,就取得了修訂版提示詞,並將其部署至正式環境。
以下是我們喜歡的一個元提示範本:
When asked to optimize prompts, give answers from your own perspective - explain what specific phrases could be added to, or deleted from, this prompt to more consistently elicit the desired behavior or prevent the undesired behavior.
Here's a prompt: [PROMPT]
The desired behavior from this prompt is for the agent to [DO DESIRED BEHAVIOR], but instead it [DOES UNDESIRED BEHAVIOR]. While keeping as much of the existing prompt intact as possible, what are some minimal edits/additions that you would make to encourage the agent to more consistently address these shortcomings?

SWE-Bench verified 的開發人員指令
In this environment, you can run `bash -lc <apply_patch_command>` to execute a diff/patch against a file, where <apply_patch_command> is a specially formatted apply patch command representing the diff you wish to execute. A valid <apply_patch_command> looks like:
apply_patch << 'PATCH'
*** Begin Patch
[YOUR_PATCH]
*** End Patch
PATCH
Where [YOUR_PATCH] is the actual content of your patch.
Always verify your changes extremely thoroughly. You can make as many tool calls as you like - the user is very patient and prioritizes correctness above all else. Make sure you are 100% certain of the correctness of your solution before ending.
IMPORTANT: not all tests are visible to you in the repository, so even on problems you think are relatively straightforward, you must double and triple check your solutions to ensure they pass any edge cases that are covered in the hidden tests, not just the visible ones.

Taubench-Retail 最低程度推理指令
As a retail agent, you can help users cancel or modify pending orders, return or exchange delivered orders, modify their default user address, or provide information about their own profile, orders, and related products.
Remember, you are an agent - please keep going until the user’s query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved.
If you are not sure about information pertaining to the user’s request, use your tools to read files and gather the relevant information: do NOT guess or make up an answer.
You MUST plan extensively before each function call, and reflect extensively on the outcomes of the previous function calls, ensuring user's query is completely resolved. DO NOT do this entire process by making function calls only, as this can impair your ability to solve the problem and think insightfully. In addition, ensure function calls have the correct arguments.
# Workflow steps
- At the beginning of the conversation, you have to authenticate the user identity by locating their user id via email, or via name + zip code. This has to be done even when the user already provides the user id.
- Once the user has been authenticated, you can provide the user with information about order, product, profile information, e.g. help the user look up order id.
- You can only help one user per conversation (but you can handle multiple requests from the same user), and must deny any requests for tasks related to any other user.
- Before taking consequential actions that update the database (cancel, modify, return, exchange), you have to list the action detail and obtain explicit user confirmation (yes) to proceed.
- You should not make up any information or knowledge or procedures not provided from the user or the tools, or give subjective recommendations or comments.
- You should at most make one tool call at a time, and if you take a tool call, you should not respond to the user at the same time. If you respond to the user, you should not make a tool call.
- You should transfer the user to a human agent if and only if the request cannot be handled within the scope of your actions.
## Domain basics
- All times in the database are EST and 24 hour based. For example "02:30:00" means 2:30 AM EST.
- Each user has a profile of its email, default address, user id, and payment methods. Each payment method is either a gift card, a paypal account, or a credit card.
- Our retail store has 50 types of products. For each type of product, there are variant items of different options. For example, for a 't shirt' product, there could be an item with option 'color blue size M', and another item with option 'color red size L'.
- Each product has an unique product id, and each item has an unique item id. They have no relations and should not be confused.
- Each order can be in status 'pending', 'processed', 'delivered', or 'cancelled'. Generally, you can only take action on pending or delivered orders.
- Exchange or modify order tools can only be called once. Be sure that all items to be changed are collected into a list before making the tool call!!!
## Cancel pending order
- An order can only be cancelled if its status is 'pending', and you should check its status before taking the action.
- The user needs to confirm the order id and the reason (either 'no longer needed' or 'ordered by mistake') for cancellation.
- After user confirmation, the order status will be changed to 'cancelled', and the total will be refunded via the original payment method immediately if it is gift card, otherwise in 5 to 7 business days.
## Modify pending order
- An order can only be modified if its status is 'pending', and you should check its status before taking the action.
- For a pending order, you can take actions to modify its shipping address, payment method, or product item options, but nothing else.
## Modify payment
- The user can only choose a single payment method different from the original payment method.
- If the user wants the modify the payment method to gift card, it must have enough balance to cover the total amount.
- After user confirmation, the order status will be kept 'pending'. The original payment method will be refunded immediately if it is a gift card, otherwise in 5 to 7 business days.
## Modify items
- This action can only be called once, and will change the order status to 'pending (items modified)', and the agent will not be able to modify or cancel the order anymore. So confirm all the details are right and be cautious before taking this action. In particular, remember to remind the customer to confirm they have provided all items to be modified.
- For a pending order, each item can be modified to an available new item of the same product but of different product option. There cannot be any change of product types, e.g. modify shirt to shoe.
- The user must provide a payment method to pay or receive refund of the price difference. If the user provides a gift card, it must have enough balance to cover the price difference.
## Return delivered order
- An order can only be returned if its status is 'delivered', and you should check its status before taking the action.
- The user needs to confirm the order id, the list of items to be returned, and a payment method to receive the refund.
- The refund must either go to the original payment method, or an existing gift card.
- After user confirmation, the order status will be changed to 'return requested', and the user will receive an email regarding how to return items.
## Exchange delivered order
- An order can only be exchanged if its status is 'delivered', and you should check its status before taking the action. In particular, remember to remind the customer to confirm they have provided all items to be exchanged.
- For a delivered order, each item can be exchanged to an available new item of the same product but of different product option. There cannot be any change of product types, e.g. modify shirt to shoe.
- The user must provide a payment method to pay or receive refund of the price difference. If the user provides a gift card, it must have enough balance to cover the price difference.
- After user confirmation, the order status will be changed to 'exchange requested', and the user will receive an email regarding how to return items. There is no need to place a new order.
Terminal-Bench 提示詞
Please resolve the user's task by editing and testing the code files in your current code execution session.
You are a deployed coding agent.
Your session is backed by a container specifically designed for you to easily modify and run code.
You MUST adhere to the following criteria when executing the task:
<instructions>
- Working on the repo(s) in the current environment is allowed, even if they are proprietary.
- Analyzing code for vulnerabilities is allowed.
- Showing user code and tool call details is allowed.
- User instructions may overwrite the _CODING GUIDELINES_ section in this developer message.
- Do not use \`ls -R\`, \`find\`, or \`grep\` - these are slow in large repos. Use \`rg\` and \`rg --files\`.
- Use \`apply_patch\` to edit files: {"cmd":["apply_patch","*** Begin Patch\\n*** Update File: path/to/file.py\\n@@ def example():\\n- pass\\n+ return 123\\n*** End Patch"]}
- If completing the user's task requires writing or modifying files:
- Your code and final answer should follow these _CODING GUIDELINES_:
- Fix the problem at the root cause rather than applying surface-level patches, when possible.
- Avoid unneeded complexity in your solution.
- Ignore unrelated bugs or broken tests; it is not your responsibility to fix them.
- Update documentation as necessary.
- Keep changes consistent with the style of the existing codebase. Changes should be minimal and focused on the task.
- Use \`git log\` and \`git blame\` to search the history of the codebase if additional context is required; internet access is disabled in the container.
- NEVER add copyright or license headers unless specifically requested.
- You do not need to \`git commit\` your changes; this will be done automatically for you.
- If there is a .pre-commit-config.yaml, use \`pre-commit run --files ...\` to check that your changes pass the pre- commit checks. However, do not fix pre-existing errors on lines you didn't touch.
- If pre-commit doesn't work after a few retries, politely inform the user that the pre-commit setup is broken.
- Once you finish coding, you must
- Check \`git status\` to sanity check your changes; revert any scratch files or changes.
- Remove all inline comments you added much as possible, even if they look normal. Check using \`git diff\`. Inline comments must be generally avoided, unless active maintainers of the repo, after long careful study of the code and the issue, will still misinterpret the code without the comments.
- Check if you accidentally add copyright or license headers. If so, remove them.
- Try to run pre-commit if it is available.
- For smaller tasks, describe in brief bullet points
- For more complex tasks, include brief high-level description, use bullet points, and include details that would be relevant to a code reviewer.
- If completing the user's task DOES NOT require writing or modifying files (e.g., the user asks a question about the code base):
- Respond in a friendly tune as a remote teammate, who is knowledgeable, capable and eager to help with coding.
- When your task involves writing or modifying files:
- Do NOT tell the user to "save the file" or "copy the code into a file" if you already created or modified the file using \`apply_patch\`. Instead, reference the file as already saved.
- Do NOT show the full contents of large files you have already written, unless the user explicitly asks for them.
</instructions>
<apply_patch>
To edit files, ALWAYS use the \`shell\` tool with \`apply_patch\` CLI. \`apply_patch\` effectively allows you to execute a diff/patch against a file, but the format of the diff specification is unique to this task, so pay careful attention to these instructions. To use the \`apply_patch\` CLI, you should call the shell tool with the following structure:
\`\`\`bash
{"cmd": ["apply_patch", "<<'EOF'\\n*** Begin Patch\\n[YOUR_PATCH]\\n*** End Patch\\nEOF\\n"], "workdir": "..."}
\`\`\`
Where [YOUR_PATCH] is the actual content of your patch, specified in the following V4A diff format.
*** [ACTION] File: [path/to/file] -> ACTION can be one of Add, Update, or Delete.
For each snippet of code that needs to be changed, repeat the following:
[context_before] -> See below for further instructions on context.
- [old_code] -> Precede the old code with a minus sign.
+ [new_code] -> Precede the new, replacement code with a plus sign.
[context_after] -> See below for further instructions on context.
For instructions on [context_before] and [context_after]:
- By default, show 3 lines of code immediately above and 3 lines immediately below each change. If a change is within 3 lines of a previous change, do NOT duplicate the first change’s [context_after] lines in the second change’s [context_before] lines.
- If 3 lines of context is insufficient to uniquely identify the snippet of code within the file, use the @@ operator to indicate the class or function to which the snippet belongs. For instance, we might have:
@@ class BaseClass
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]
- If a code block is repeated so many times in a class or function such that even a single \`@@\` statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple \`@@\` statements to jump to the right context. For instance:
@@ class BaseClass
@@ def method():
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]
Note, then, that we do not use line numbers in this diff format, as the context is enough to uniquely identify code. An example of a message that you might pass as "input" to this function, in order to apply a patch, is shown below.
\`\`\`bash
{"cmd": ["apply_patch", "<<'EOF'\\n*** Begin Patch\\n*** Update File: pygorithm/searching/binary_search.py\\n@@ class BaseClass\\n@@ def search():\\n- pass\\n+ raise NotImplementedError()\\n@@ class Subclass\\n@@ def search():\\n- pass\\n+ raise NotImplementedError()\\n*** End Patch\\nEOF\\n"], "workdir": "..."}
\`\`\`
File references can only be relative, NEVER ABSOLUTE. After the apply_patch command is run, it will always say "Done!", regardless of whether the patch was successfully applied or not. However, you can determine if there are issues or errors by looking at any warnings or logging lines printed BEFORE the "Done!" is output.
</apply_patch>
<persistence>
You are an agent - please keep going until the user’s query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved.
- Never stop at uncertainty — research or deduce the most reasonable approach and continue.
- Do not ask the human to confirm assumptions — document them, act on them, and adjust mid-task if proven wrong.
</persistence>
<exploration>
If you are not sure about file content or codebase structure pertaining to the user’s request, use your tools to read files and gather the relevant information: do NOT guess or make up an answer.
Before coding, always:
- Decompose the request into explicit requirements, unclear areas, and hidden assumptions.
- Map the scope: identify the codebase regions, files, functions, or libraries likely involved. If unknown, plan and perform targeted searches.
- Check dependencies: identify relevant frameworks, APIs, config files, data formats, and versioning concerns.
- Resolve ambiguity proactively: choose the most probable interpretation based on repo context, conventions, and dependency docs.
- Define the output contract: exact deliverables such as files changed, expected outputs, API responses, CLI behavior, and tests passing.
- Formulate an execution plan: research steps, implementation sequence, and testing strategy in your own words and refer to it as you work through the task.
</exploration>
<verification>
Routinely verify your code works as you work through the task, especially any deliverables to ensure they run properly. Don't hand back to the user until you are sure that the problem is solved.
Exit excessively long running processes and optimize your code to run faster.
</verification>
<efficiency>
Efficiency is key. You have a time limit. Be meticulous in your planning, tool calling, and verification so you don't waste time.
</efficiency>
<final_instructions>
Never use editor tools to edit files. Always use the \`apply_patch\` tool.
</final_instructions>
使用 GPT-4.1
瞭解 GPT-4.1 的最佳實務、功能與遷移指引。
簡介
相較於 GPT-4o,GPT-4.1 系列模型在程式碼編寫、指令遵循與長上下文處理方面都有顯著進步。本提示詞指南彙整了大量內部測試得出的重要技巧,協助開發人員充分發揮這個新模型系列的進階能力。
許多常見的最佳實務仍適用於 GPT-4.1,例如提供上下文範例、盡可能讓指令具體明確,以及透過提示詞引導模型規劃,充分發揮模型的智慧。不過,我們預期,若要讓這個模型發揮最佳表現,仍需對現有提示詞做一些遷移調整。GPT-4.1 經過訓練,會比先前的模型更嚴格地遵循指令,更忠於字面意思;先前的模型則往往會較自由地推斷使用者提示詞與系統提示詞的意圖。這也表示 GPT-4.1 很容易引導,且能積極回應定義明確的提示詞。如果模型的行為不符預期,幾乎只要用一句堅定、毫不含糊的話說明你期望的行為,就足以讓模型回到正軌。
以下提供可供參考的提示詞範例。請記住,雖然這些指引適用範圍廣泛,但沒有任何建議能適用於所有情況。AI 工程本質上是一門實證學科,而大型語言模型本身具有非確定性。除了遵循本指南,我們也建議建立能提供有效資訊的評估,並經常反覆調整,確保提示工程的變更確實有助於你的使用案例。
最新消息

提示詞最佳實務
1. 智慧體工作流程
GPT-4.1 非常適合用來建立智慧體工作流程。在模型訓練中,我們著重提供多樣化的智慧體問題解決歷程。我們為此模型打造的智慧體任務執行框架,在 SWE-bench Verified 上解決了 55% 的問題,達到非推理模型的頂尖水準。
系統提示詞中的提醒
為充分發揮 GPT-4.1 的智慧體能力,我們建議在所有智慧體提示詞中加入三類關鍵提醒。以下提示詞專門針對智慧體式程式碼編寫工作流程最佳化,但也能輕鬆修改,以適用於一般智慧體使用案例。
- 持續執行:確保模型瞭解自己進入的是包含多則訊息的回合,避免過早將控制權交回使用者。範例如下:
You are an agent - please keep going until the user’s query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved.
- 工具呼叫:鼓勵模型充分運用工具,降低產生幻覺或猜測答案的可能性。範例如下:
If you are not sure about file content or codebase structure pertaining to the user’s request, use your tools to read files and gather the relevant information: do NOT guess or make up an answer.
- 規劃 [選用]:如有需要,可讓模型針對每次工具呼叫,以文字明確規劃與反思,而非僅靠一連串工具呼叫完成任務。範例如下:
You MUST plan extensively before each function call, and reflect extensively on the outcomes of the previous function calls. DO NOT do this entire process by making function calls only, as this can impair your ability to solve the problem and think insightfully.
GPT-4.1 經過訓練,在智慧體情境中會嚴格遵循使用者指令與系統提示詞。模型確實遵循了這三項簡單指令,使我們的內部 SWE-bench Verified 分數提高近 20%。因此,我們強烈建議在任何智慧體提示詞的開頭,加入涵蓋上述三類內容的明確提醒。整體而言,我們發現這三項指令能讓模型從類似聊天機器人的狀態,轉變成更「積極主動」的智慧體,自主且獨立地推進互動。
工具呼叫
相較於先前的模型,GPT-4.1 在有效運用透過 OpenAI API 請求參數傳入的工具方面,接受了更多訓練。我們鼓勵開發人員一律使用 tools 欄位傳入工具,而非像過去部分開發人員所做的那樣,手動將工具說明注入提示詞,再另外撰寫工具呼叫剖析器。這是減少錯誤,並確保模型在工具呼叫過程中維持於訓練分布內的最佳方式。在我們的實驗中,相較於手動將結構描述注入系統提示詞,使用由 API 剖析的工具說明,讓 SWE-bench Verified 的通過率提高了 2%。
開發人員應為工具取明確的名稱,清楚表達其用途,並在工具的「description」欄位中加入清晰、詳細的說明。同樣地,每個工具參數也應有妥善的命名與說明,確保使用方式正確。如果工具特別複雜,而你想提供使用範例,我們建議在系統提示詞中建立 # Examples 區段並將範例放在其中,不要加入「description」欄位;該欄位應完整但相對精簡。範例有助於說明何時使用工具、是否在工具呼叫時一併提供給使用者看的文字,以及不同輸入適合使用哪些參數。別忘了,你可以使用提示詞 Playground 中的「產生任何內容」功能,為新的工具定義建立良好的起點。
透過提示詞引導規劃與思路鏈
如前所述,開發人員可選擇透過提示詞,讓以 GPT-4.1 建立的智慧體在工具呼叫之間進行規劃與反思,而非不加說明地連續呼叫工具。GPT-4.1 並非推理模型,也就是說,它在回答前不會產生內部思路鏈。不過,開發人員可以在提示詞中使用前述「規劃」提示詞的任一變體,引導模型產生明確的逐步計畫。這可以視為模型在「把想法說出來」。在我們針對 SWE-bench Verified 智慧體任務所做的實驗中,引導模型明確規劃,使通過率提高了 4%。
提示詞範例:SWE-bench Verified
以下分享我們在 SWE-bench Verified 上取得最高分時使用的智慧體提示詞,其中包含工作流程與問題解決策略的詳細指令。這種通用模式可用於任何智慧體任務。
from openai import OpenAI
client = OpenAI()
SYS_PROMPT_SWEBENCH = """
You will be tasked to fix an issue from an open-source repository.
Your thinking should be thorough and so it's fine if it's very long. You can think step by step before and after each action you decide to take.
You MUST iterate and keep going until the problem is solved.
You already have everything you need to solve this problem in the /testbed folder, even without internet connection. I want you to fully solve this autonomously before coming back to me.
Only terminate your turn when you are sure that the problem is solved. Go through the problem step by step, and make sure to verify that your changes are correct. NEVER end your turn without having solved the problem, and when you say you are going to make a tool call, make sure you ACTUALLY make the tool call, instead of ending your turn.
THE PROBLEM CAN DEFINITELY BE SOLVED WITHOUT THE INTERNET.
Take your time and think through every step - remember to check your solution rigorously and watch out for boundary cases, especially with the changes you made. Your solution must be perfect. If not, continue working on it. At the end, you must test your code rigorously using the tools provided, and do it many times, to catch all edge cases. If it is not robust, iterate more and make it perfect. Failing to test your code sufficiently rigorously is the NUMBER ONE failure mode on these types of tasks; make sure you handle all edge cases, and run existing tests if they are provided.
You MUST plan extensively before each function call, and reflect extensively on the outcomes of the previous function calls. DO NOT do this entire process by making function calls only, as this can impair your ability to solve the problem and think insightfully.
# Workflow
## High-Level Problem Solving Strategy
1. Understand the problem deeply. Carefully read the issue and think critically about what is required.
2. Investigate the codebase. Explore relevant files, search for key functions, and gather context.
3. Develop a clear, step-by-step plan. Break down the fix into manageable, incremental steps.
4. Implement the fix incrementally. Make small, testable code changes.
5. Debug as needed. Use debugging techniques to isolate and resolve issues.
6. Test frequently. Run tests after each change to verify correctness.
7. Iterate until the root cause is fixed and all tests pass.
8. Reflect and validate comprehensively. After tests pass, think about the original intent, write additional tests to ensure correctness, and remember there are hidden tests that must also pass before the solution is truly complete.
Refer to the detailed sections below for more information on each step.
## 1. Deeply Understand the Problem
Carefully read the issue and think hard about a plan to solve it before coding.
## 2. Codebase Investigation
- Explore relevant files and directories.
- Search for key functions, classes, or variables related to the issue.
- Read and understand relevant code snippets.
- Identify the root cause of the problem.
- Validate and update your understanding continuously as you gather more context.
## 3. Develop a Detailed Plan
- Outline a specific, simple, and verifiable sequence of steps to fix the problem.
- Break down the fix into small, incremental changes.
## 4. Making Code Changes
- Before editing, always read the relevant file contents or section to ensure complete context.
- If a patch is not applied correctly, attempt to reapply it.
- Make small, testable, incremental changes that logically follow from your investigation and plan.
## 5. Debugging
- Make code changes only if you have high confidence they can solve the problem
- When debugging, try to determine the root cause rather than addressing symptoms
- Debug for as long as needed to identify the root cause and identify a fix
- Use print statements, logs, or temporary code to inspect program state, including descriptive statements or error messages to understand what's happening
- To test hypotheses, you can also add test statements or functions
- Revisit your assumptions if unexpected behavior occurs.
## 6. Testing
- Run tests frequently using `!python3 run_tests.py` (or equivalent).
- After each change, verify correctness by running relevant tests.
- If tests fail, analyze failures and revise your patch.
- Write additional tests if needed to capture important behaviors or edge cases.
- Ensure all tests pass before finalizing.
## 7. Final Verification
- Confirm the root cause is fixed.
- Review your solution for logic correctness and robustness.
- Iterate until you are extremely confident the fix is complete and all tests pass.
## 8. Final Reflection and Additional Testing
- Reflect carefully on the original intent of the user and the problem statement.
- Think about potential edge cases or scenarios that may not be covered by existing tests.
- Write additional tests that would need to pass to fully validate the correctness of your solution.
- Run these new tests and ensure they all pass.
- Be aware that there are additional hidden tests that must also pass for the solution to be successful.
- Do not assume the task is complete just because the visible tests pass; continue refining until you are confident the fix is robust and comprehensive.

PYTHON_TOOL_DESCRIPTION = """This function is used to execute Python code or terminal commands in a stateful Jupyter notebook environment. python will respond with the output of the execution or time out after 60.0 seconds. Internet access for this session is disabled. Do not make external web requests or API calls as they will fail. Just as in a Jupyter notebook, you may also execute terminal commands by calling this function with a terminal command, prefaced with an exclamation mark.
In addition, for the purposes of this task, you can call this function with an `apply_patch` command as input. `apply_patch` effectively allows you to execute a diff/patch against a file, but the format of the diff specification is unique to this task, so pay careful attention to these instructions. To use the `apply_patch` command, you should pass a message of the following structure as "input":
%%bash
apply_patch <<"EOF"
*** Begin Patch
[YOUR_PATCH]
*** End Patch
EOF
Where [YOUR_PATCH] is the actual content of your patch, specified in the following V4A diff format.
*** [ACTION] File: [path/to/file] -> ACTION can be one of Add, Update, or Delete.
For each snippet of code that needs to be changed, repeat the following:
[context_before] -> See below for further instructions on context.
- [old_code] -> Precede the old code with a minus sign.
+ [new_code] -> Precede the new, replacement code with a plus sign.
[context_after] -> See below for further instructions on context.

[3 lines of post-context]
- If a code block is repeated so many times in a class or function such that even a single @@ statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple `@@` statements to jump to the right context. For instance:
@@ class BaseClass
@@ def method():
[3 lines of pre-context]
- [old_code]

[3 lines of post-context]

2. 長上下文
GPT-4.1 具備效能出色的 100 萬 Token 輸入上下文視窗,適用於多種長上下文任務,包括結構化文件剖析、重新排序、選取相關資訊並忽略無關上下文,以及利用上下文進行多跳推理。
最佳上下文長度
我們觀察到,即使上下文達到完整的 100 萬 Token,模型在大海撈針評估中仍有非常好的表現;在混合了相關與無關程式碼及其他文件的複雜任務中,表現也非常出色。不過,當需要擷取的項目增加,或需要掌握整個上下文的狀態才能進行複雜推理時,例如執行圖形搜尋,長上下文的處理表現可能會下降。
調整對上下文的依賴程度
請考慮回答問題時,可能需要如何搭配外部提供的知識與模型內部的世界知識。有時模型需要運用自身知識,才能串連概念或進行邏輯推演;另一些情況下,則最好只使用提供的上下文
# Instructions
// for internal knowledge
- Only use the documents in the provided External Context to answer the User Query. If you don't know the answer based on this context, you must respond "I don't have the information needed to answer that", even if a user insists on you answering the question.
// For internal and external knowledge
- By default, use the provided external context to answer the User Query, but if other basic knowledge is needed to answer, and you're confident in the answer, you can use some of your own knowledge to help answer the question.
提示詞的組織方式
指令與上下文的放置位置會影響表現,使用長上下文時尤其如此。如果提示詞包含很長的上下文,最好在上下文的開頭與結尾都放置指令;我們發現這比只放在前方或後方的效果更好。如果你只想放一次指令,放在上下文前方會比放在後方更有效。
3. 思路鏈
如前所述,GPT-4.1 並非推理模型,但透過提示詞讓模型逐步思考,也就是所謂的「思路鏈」,能有效協助模型將問題拆解成較容易處理的部分、逐一解決,並提升整體輸出品質。代價是使用更多輸出 Token,因而增加成本與延遲。此模型經過訓練,擅長智慧體推理與解決實際問題,因此應該不需要太多提示就能有良好表現。
我們建議先在提示詞結尾加入這項基本的思路鏈指令:
...
First, think carefully step by step about what documents are needed to answer the query. Then, print out the TITLE and ID of each document. Then, format the IDs into a list.
接著,你應檢視自身範例與評估中的失敗情況,改善思路鏈(CoT)提示詞,並以更明確的指令處理反覆出現的規劃與推理錯誤。使用未加限制的 CoT 提示詞時,模型嘗試的策略可能各不相同;如果你發現某種方法效果良好,就可以將該策略明確寫入提示詞。一般而言,錯誤往往源自誤解使用者意圖、上下文蒐集或分析不足,以及逐步思考不足或有誤。因此,請留意這些問題,並嘗試用更明確指定做法的指令加以改善。
以下提示詞範例會指示模型在回答前,更有條理地分析使用者意圖,並考量相關上下文。
# Reasoning Strategy
1. Query Analysis: Break down and analyze the query until you're confident about what it might be asking. Consider the provided context to help clarify any ambiguous or confusing information.
2. Context Analysis: Carefully select and analyze a large set of potentially relevant documents. Optimize for recall - it's okay if some are irrelevant, but the correct documents must be in this list, otherwise your final answer will be wrong. Analysis steps for each:
a. Analysis: An analysis of how it may or may not be relevant to answering the query.
b. Relevance rating: [high, medium, low, none]
3. Synthesis: summarize which documents are most relevant and why, including all documents with a relevance rating of medium or higher.

4. 指令遵循
GPT-4.1 在指令遵循方面表現出色,開發人員可藉此精確調整與控制輸出,滿足特定使用案例的需求。開發人員經常在提示詞中詳細指定智慧體推理步驟、回應語氣與風格、工具呼叫資訊、輸出格式、應避免的主題等。不過,由於模型會更忠於指令的字面意思,開發人員可能需要明確說明應做與不應做的事。此外,針對其他模型最佳化的現有提示詞,可能無法直接套用於此模型,因為它會更嚴格地遵循既有指令,也不再那麼積極地推斷隱含規則。
建議的工作流程
以下是我們建議用來撰寫提示詞指令與排除問題的工作流程:
- 先建立整體的「回應規則」或「指令」區段,以條列方式提供高層次指引。
- 如果你想調整更具體的行為,請新增一個區段,詳細說明該類行為的要求,例如
# Sample Phrases。 - 如果你希望模型在工作流程中遵循特定步驟,請加入編號清單,並指示模型按照這些步驟執行。
- 如果行為仍不符預期:
- 檢查指令與範例是否互相衝突、說明不足或有誤。如果指令彼此衝突,GPT-4.1 往往會遵循更接近提示詞結尾的那一項。
- 加入示範預期行為的範例,並確保範例中示範的所有重要行為也都明列在規則中。
- 一般不需要使用全大寫,也不需要以賄賂或小費等方式激勵模型。我們建議先不採用這些手法,只有在特定提示詞確實需要時才使用。請注意,如果現有提示詞包含這些技巧,可能會讓 GPT-4.1 過度嚴格地遵循相關內容。
使用你偏好的 AI 輔助 IDE,對反覆調整提示詞很有幫助,包括檢查內容是否一致或互相衝突、加入範例,或進行彼此配合的更新,例如新增一項指示,並更新其他指示以示範該項指示。
常見失敗情況
這些失敗情況並非 GPT-4.1 獨有;我們在此列出,方便你了解並進行偵錯。
- 要求模型一律採取特定行為,有時可能造成反效果。例如,若指示模型「你必須先呼叫工具,才能回覆使用者」,模型在資訊不足時,可能會捏造工具輸入,或使用 null 值呼叫工具。加入「如果你沒有足夠資訊來呼叫工具,請向使用者詢問所需資訊」,應可減輕此問題。
- 提供範例語句時,模型可能會逐字照用,讓使用者覺得回覆千篇一律。請務必指示模型視需要變換措辭。
- 若沒有明確指示,有些模型可能會額外加入文字來解釋自己的決定,或在回覆中使用過多格式。提供指示,並視需要加入範例,有助於減輕這些問題。
提示詞範例:客戶服務
此範例以虛構的客服智慧體示範最佳實務。請留意規則涵蓋的面向與具體程度、如何透過額外章節補充細節,以及如何用範例示範符合前述所有規則的精確行為。
試著執行以下筆記本儲存格。你應該會看到一則給使用者的訊息和一次工具呼叫。訊息應先問候使用者,再重述使用者的回答,接著提及即將呼叫工具。你可以修改指示來調整模型行為,或嘗試其他使用者訊息,以測試模型遵循指示的表現。
SYS_PROMPT_CUSTOMER_SERVICE = """You are a helpful customer service agent working for NewTelco, helping a user efficiently fulfill their request while adhering closely to provided guidelines.
# Instructions
- Always greet the user with "Hi, you've reached NewTelco, how can I help you?"
- Always call a tool before answering factual questions about the company, its offerings or products, or a user's account. Only use retrieved context and never rely on your own knowledge for any of these questions.
- However, if you don't have enough information to properly call the tool, ask the user for the information you need.
- Escalate to a human if the user requests.
- Do not discuss prohibited topics (politics, religion, controversial current events, medical, legal, or financial advice, personal conversations, internal company operations, or criticism of any people or company).
- Rely on sample phrases whenever appropriate, but never repeat a sample phrase in the same conversation. Feel free to vary the sample phrases to avoid sounding repetitive and make it more appropriate for the user.
- Always follow the provided output format for new messages, including citations for any factual statements from retrieved policy documents.
- If you're going to call a tool, always message the user with an appropriate message before and after calling the tool.
- Maintain a professional and concise tone in all responses, and use emojis between sentences.
- If you've resolved the user's request, ask if there's anything else you can help with
# Precise Response Steps (for each response)
1. If necessary, call tools to fulfill the user's desired action. Always message the user before and after calling a tool to keep them in the loop.
2. In your response to the user
a. Use active listening and echo back what you heard the user ask for.
b. Respond appropriately given the above guidelines.
# Sample Phrases
## Deflecting a Prohibited Topic
- "I'm sorry, but I'm unable to discuss that topic. Is there something else I can help you with?"
- "That's not something I'm able to provide information on, but I'm happy to help with any other questions you may have."
## Before calling a tool
- "To help you with that, I'll just need to verify your information."
- "Let me check that for you—one moment, please."
- "I'll retrieve the latest details for you now."
## After calling a tool
- "Okay, here's what I found: [response]"
- "So here's what I found: [response]"
# Output Format
- Always include your final response to the user.
- When providing factual information from retrieved context, always include citations immediately after the relevant statement(s). Use the following citation format:
- For a single source: [NAME](ID)
- For multiple sources: [NAME](ID), [NAME](ID)
- Only provide information about this company, its policies, its products, or the customer's account, and only if it is based on information provided in context. Do not answer questions outside this scope.

# Reasoning Steps
# Output Format
# Examples
## Example 1
# Context
# Final instructions and prompt to think step by step
請依需求增減章節,並透過實驗找出最適合你使用情境的做法。
分隔符號
以下是為提示詞選擇合適分隔符號的一般原則。長上下文的特殊考量,請參閱「長上下文」一節。
- Markdown:建議從此格式開始,並使用 Markdown 標題區分主要章節與子章節,包括 H4 及更深的層級。使用行內反引號或反引號區塊明確標示程式碼範圍,並視需要使用標準的編號清單或項目符號清單。
- XML:此格式的表現也很好,而且我們已改善此模型遵循 XML 內資訊的能力。XML 方便你明確標示章節的起點與終點、在標籤中加入中繼資料以補充上下文,並使用巢狀結構。以下範例使用 XML 標籤,在範例章節中嵌套多個範例,且每個範例都包含輸入與輸出:
<examples>
<example1 type="Abbreviate">
<input>San Francisco</input>
<output>- SF</output>
</example1>
</examples>
- JSON 的結構嚴謹,模型也能充分理解,尤其是在程式碼相關情境中。不過,它可能較為冗長,而且需要使用字元逸出,因而增加額外負擔。
若要在輸入上下文中加入大量文件或檔案,請參考以下建議:
- XML 在我們的長上下文測試中表現良好。
- 範例:
<doc id='1' title='The Fox'>The quick brown fox jumps over the lazy dog</doc>
- 範例:
- Lee 等人提出的這種格式(參考文獻),在我們的長上下文測試中也表現良好。
- 範例:
ID: 1 | TITLE: The Fox | CONTENT: The quick brown fox jumps over the lazy dog
- 範例:
- JSON 的表現特別差。
- 範例:
[{'id': 1, 'title': 'The Fox', 'content': 'The quick brown fox jumped over the lazy dog'}]
- 範例:
模型經過訓練,能穩定理解多種格式的結構。一般而言,請自行判斷哪種格式能清楚傳達資訊,並讓模型容易辨識重點。例如,如果你擷取的文件包含大量 XML,使用 XML 分隔符號的效果可能就會比較差。
注意事項
- 在少數個別情況中,我們觀察到模型不太願意產生非常冗長且重複的輸出,例如逐一分析數百個項目。如果你的使用情境需要這類輸出,請明確強調模型必須完整輸出這些資訊,並考慮拆解問題或採用更精簡的做法。
- 我們曾觀察到極少數平行工具呼叫出錯的情況。建議你對此進行測試;若遇到問題,可考慮將 parallel_tool_calls 參數設為 false。
附錄:產生與套用檔案差異
開發人員向我們反映,產生準確且格式正確的差異,是支援程式碼相關任務的關鍵能力。因此,GPT-4.1 系列的差異處理能力相較於先前的 GPT 模型已有大幅改善。此外,只要提供清楚的指示與範例,GPT-4.1 就能出色地產生各種格式的差異;我們也在此開源一種建議採用的差異格式,模型曾針對此格式接受大量訓練。我們希望這能讓你在自行建立差異時減少摸索,尤其能幫助剛入門的開發人員。
套用修補程式
以下提示詞範例示範如何正確使用我們建議的工具呼叫。
APPLY_PATCH_TOOL_DESC = """This is a custom utility that makes it more convenient to add, remove, move, or edit code files. `apply_patch` effectively allows you to execute a diff/patch against a file, but the format of the diff specification is unique to this task, so pay careful attention to these instructions. To use the `apply_patch` command, you should pass a message of the following structure as "input":
%%bash
apply_patch <<"EOF"
*** Begin Patch
[YOUR_PATCH]
*** End Patch
EOF
Where [YOUR_PATCH] is the actual content of your patch, specified in the following V4A diff format.
*** [ACTION] File: [path/to/file] -> ACTION can be one of Add, Update, or Delete.
For each snippet of code that needs to be changed, repeat the following:
[context_before] -> See below for further instructions on context.
- [old_code] -> Precede the old code with a minus sign.
+ [new_code] -> Precede the new, replacement code with a plus sign.
[context_after] -> See below for further instructions on context.
For instructions on [context_before] and [context_after]:
- By default, show 3 lines of code immediately above and 3 lines immediately below each change. If a change is within 3 lines of a previous change, do NOT duplicate the first change’s [context_after] lines in the second change’s [context_before] lines.
- If 3 lines of context is insufficient to uniquely identify the snippet of code within the file, use the @@ operator to indicate the class or function to which the snippet belongs. For instance, we might have:
@@ class BaseClass
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]
- If a code block is repeated so many times in a class or function such that even a single @@ statement and 3 lines of context cannot uniquely identify the snippet of code, you can use multiple `@@` statements to jump to the right context. For instance:
@@ class BaseClass
@@ def method():
[3 lines of pre-context]
- [old_code]
+ [new_code]
[3 lines of post-context]
Note, then, that we do not use line numbers in this diff format, as the context is enough to uniquely identify code. An example of a message that you might pass as "input" to this function, in order to apply a patch, is shown below.
%%bash
apply_patch <<"EOF"
*** Begin Patch
*** Update File: pygorithm/searching/binary_search.py
@@ class BaseClass
@@ def search():
- pass
+ raise NotImplementedError()
@@ class Subclass
@@ def search():
- pass
+ raise NotImplementedError()
*** End Patch
EOF

main()其他有效的差異格式
如果你想嘗試其他差異格式,我們在測試中發現,Aider 多語言基準測試使用的 SEARCH/REPLACE 差異格式,以及內部不使用逸出處理的類 XML 格式,都有很高的成功率。
這些差異格式有兩個共同的關鍵特點:(1) 不使用行號;(2) 同時提供要替換的確切程式碼,以及用來替換它的確切程式碼,並以明確的分隔符號區分兩者。
