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

The model that the assistant used for this run.

object: "thread.run"

The object type, which is always thread.run.

parallel_tool_calls: boolean

Whether to enable parallel function calling during tool use.

required_action: RequiredAction | null

Details on the action required to continue the run. Will be null if no action is required.

submit_tool_outputs: SubmitToolOutputs { tool_calls }

Details on the tool outputs needed for this run to continue.

tool_calls: Array<RequiredActionFunctionToolCall { id, function, type } >

A list of the relevant tool calls.

id: string

The ID of the tool call. This ID must be referenced when you submit the tool outputs in using the Submit tool outputs to run endpoint.

function: Function { arguments, name }

The function definition.

arguments: string

The arguments that the model expects you to pass to the function.

name: string

The name of the function.

type: "function"

The type of tool call the output is required for. For now, this is always function.

type: "submit_tool_outputs"

For now, this is always submit_tool_outputs.

response_format: AssistantResponseFormatOption | null

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.

One of the following:
"auto"
"auto"
ResponseFormatText { type }

Default response format. Used to generate text responses.

type: "text"

The type of response format being defined. Always text.

ResponseFormatJSONObject { type }

JSON object response format. An older method of generating JSON responses. Using json_schema is recommended for models that support it. Note that the model will not generate JSON without a system or user message instructing it to do so.

type: "json_object"

The type of response format being defined. Always json_object.

ResponseFormatJSONSchema { json_schema, type }

JSON Schema response format. Used to generate structured JSON responses. Learn more about Structured Outputs.

json_schema: JSONSchema { name, description, schema, strict }

Structured Outputs configuration options, including a JSON Schema.

name: string

The name of the response format. Must be a-z, A-Z, 0-9, or contain underscores and dashes, with a maximum length of 64.

description?: string

A description of what the response format is for, used by the model to determine how to respond in the format.

schema?: Record<string, unknown>

The schema for the response format, described as a JSON Schema object. Learn how to build JSON schemas here.

strict?: boolean | null

Whether to enable strict schema adherence when generating the output. If set to true, the model will always follow the exact schema defined in the schema field. Only a subset of JSON Schema is supported when strict is true. To learn more, read the Structured Outputs guide.

type: "json_schema"

The type of response format being defined. Always json_schema.

started_at: number | null

The Unix timestamp (in seconds) for when the run was started.

status: RunStatus

The status of the run, which can be either queued, in_progress, requires_action, cancelling, cancelled, failed, completed, incomplete, or expired.

One of the following:
"queued"
"in_progress"
"requires_action"
"cancelling"
"cancelled"
"failed"
"completed"
"incomplete"
"expired"
thread_id: string

The ID of the thread that was executed on as a part of this run.

tool_choice: AssistantToolChoiceOption | null

Controls which (if any) tool is called by the model. none means the model will not call any tools and instead generates a message. auto is the default value and means the model can pick between generating a message or calling one or more tools. required means the model must call one or more tools before responding to the user. Specifying a particular tool like {"type": "file_search"} or {"type": "function", "function": {"name": "my_function"}} forces the model to call that tool.

One of the following:
"none" | "auto" | "required"
"none"
"auto"
"required"
AssistantToolChoice { type, function }

Specifies a tool the model should use. Use to force the model to call a specific tool.

type: "function" | "code_interpreter" | "file_search"

The type of the tool. If type is function, the function name must be set

One of the following:
"function"
"code_interpreter"
"file_search"
function?: AssistantToolChoiceFunction { name }
name: string

The name of the function to call.

tools: Array<AssistantTool>

The list of tools that the assistant used for this run.

One of the following:
CodeInterpreterTool { type }
type: "code_interpreter"

The type of tool being defined: code_interpreter

FileSearchTool { type, file_search }
type: "file_search"

The type of tool being defined: file_search

One of the following:
FunctionTool { function, type }
function: FunctionDefinition { name, description, parameters, strict }
name: string

The name of the function to be called. Must be a-z, A-Z, 0-9, or contain underscores and dashes, with a maximum length of 64.

description?: string

A description of what the function does, used by the model to choose when and how to call the function.

parameters?: FunctionParameters

The parameters the functions accepts, described as a JSON Schema object. See the guide for examples, and the JSON Schema reference for documentation about the format.

Omitting parameters defines a function with an empty parameter list.

strict?: boolean | null

Whether to enable strict schema adherence when generating the function call. If set to true, the model will follow the exact schema defined in the parameters field. Only a subset of JSON Schema is supported when strict is true. Learn more about Structured Outputs in the function calling guide.

type: "function"

The type of tool being defined: function

truncation_strategy: TruncationStrategy | null

Controls for how a thread will be truncated prior to the run. Use this to control the initial context window of the run.

type: "auto" | "last_messages"

The truncation strategy to use for the thread. The default is auto. If set to last_messages, the thread will be truncated to the n most recent messages in the thread. When set to auto, messages in the middle of the thread will be dropped to fit the context length of the model, max_prompt_tokens.

One of the following:
"auto"
"last_messages"
last_messages?: number | null

The number of most recent messages from the thread when constructing the context for the run.

minimum1
usage: Usage | null
