type Assistant struct{…}

Represents an assistant that can call the model and use tools.

ID string

The identifier, which can be referenced in API endpoints.

CreatedAt int64

The Unix timestamp (in seconds) for when the assistant was created.

Description string

The description of the assistant. The maximum length is 512 characters.

maxLength512
Instructions string

The system instructions that the assistant uses. The maximum length is 256,000 characters.

maxLength256000
Metadata Metadata

Set of 16 key-value pairs that can be attached to an object. This can be useful for storing additional information about the object in a structured format, and querying for objects via API or the dashboard.

Keys are strings with a maximum length of 64 characters. Values are strings with a maximum length of 512 characters.

Model string

ID of the model to use. You can use the List models API to see all of your available models, or see our Model overview for descriptions of them.

Name string

The name of the assistant. The maximum length is 256 characters.

maxLength256
Object Assistant

The object type, which is always assistant.

A list of tool enabled on the assistant. There can be a maximum of 128 tools per assistant. Tools can be of types code_interpreter, file_search, or function.

Accepts one of the following:

type FileSearchTool struct{…}
Type FileSearch

The type of tool being defined: file_search

Accepts one of the following:
type FunctionTool struct{…}

The type of tool being defined: function

ResponseFormat AssistantResponseFormatOptionUnionoptional

Specifies the format that the model must output. Compatible with GPT-4o, GPT-4 Turbo, and all GPT-3.5 Turbo models since gpt-3.5-turbo-1106.

Setting to { "type": "json_schema", "json_schema": {...} } enables Structured Outputs which ensures the model will match your supplied JSON schema. Learn more in the Structured Outputs guide.

Setting to { "type": "json_object" } enables JSON mode, which ensures the message the model generates is valid JSON.

Important: when using JSON mode, you must also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if finish_reason="length", which indicates the generation exceeded max_tokens or the conversation exceeded the max context length.

Temperature float64optional

What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

minimum0
maximum2
ToolResources AssistantToolResourcesoptional

A set of resources that are used by the assistant's tools. The resources are specific to the type of tool. For example, the code_interpreter tool requires a list of file IDs, while the file_search tool requires a list of vector store IDs.

CodeInterpreter AssistantToolResourcesCodeInterpreteroptional
FileIDs []stringoptional

A list of file IDs made available to the `code_interpreter`` tool. There can be a maximum of 20 files associated with the tool.

TopP float64optional

An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.

We generally recommend altering this or temperature but not both.

minimum0
maximum1
type AssistantDeleted struct{…}
ID string
Deleted bool
Object AssistantDeleted
type AssistantStreamEventUnion interface{…}

Represents an event emitted when streaming a Run.

Each event in a server-sent events stream has an event and data property:

event: thread.created
data: {"id": "thread_123", "object": "thread", ...}

We emit events whenever a new object is created, transitions to a new state, or is being streamed in parts (deltas). For example, we emit thread.run.created when a new run is created, thread.run.completed when a run completes, and so on. When an Assistant chooses to create a message during a run, we emit a thread.message.created event, a thread.message.in_progress event, many thread.message.delta events, and finally a thread.message.completed event.

We may add additional events over time, so we recommend handling unknown events gracefully in your code. See the Assistants API quickstart to learn how to integrate the Assistants API with streaming.

type AssistantResponseFormatOptionUnion interface{…}

Specifies the format that the model must output. Compatible with GPT-4o, GPT-4 Turbo, and all GPT-3.5 Turbo models since gpt-3.5-turbo-1106.

Setting to { "type": "json_schema", "json_schema": {...} } enables Structured Outputs which ensures the model will match your supplied JSON schema. Learn more in the Structured Outputs guide.

Setting to { "type": "json_object" } enables JSON mode, which ensures the message the model generates is valid JSON.

Important: when using JSON mode, you must also instruct the model to produce JSON yourself via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if finish_reason="length", which indicates the generation exceeded max_tokens or the conversation exceeded the max context length.

Accepts one of the following:
type Auto string

auto is the default value

type ResponseFormatText struct{…}

Default response format. Used to generate text responses.

Type Text

The type of response format being defined. Always text.
