The run object
Beta

Represents an execution run on a thread.source

The identifier, which can be referenced in API endpoints.source

The object type, which is always thread.run.source

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

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

The ID of the assistant used for execution of this run.source

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

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

The last error associated with this run. Will be null if there are no errors.source

The Unix timestamp (in seconds) for when the run will expire.source

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

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

The Unix timestamp (in seconds) for when the run failed.source

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

Details on why the run is incomplete. Will be null if the run is not incomplete.source

The model that the assistant used for this run.source

The instructions that the assistant used for this run.source

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

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. Keys can be a maximum of 64 characters long and values can be a maximum of 512 characters long.source

Usage statistics related to the run. This value will be null if the run is not in a terminal state (i.e. in_progress, queued, etc.).source

The sampling temperature used for this run. If not set, defaults to 1.source

The nucleus sampling value used for this run. If not set, defaults to 1.source

The maximum number of prompt tokens specified to have been used over the course of the run.source

The maximum number of completion tokens specified to have been used over the course of the run.source

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

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.source

Whether to enable parallel function calling during tool use.source

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.source

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.source

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

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.source
