Create thread and Run

The ID of the assistant to use to execute this run.

Override the default system message of the assistant. This is useful for modifying the behavior on a per-run basis.

The maximum number of completion tokens that may be used over the course of the run. The run will make a best effort to use only the number of completion tokens specified, across multiple turns of the run. If the run exceeds the number of completion tokens specified, the run will end with status incomplete. See incomplete_details for more info.

The maximum number of prompt tokens that may be used over the course of the run. The run will make a best effort to use only the number of prompt tokens specified, across multiple turns of the run. If the run exceeds the number of prompt tokens specified, the run will end with status incomplete. See incomplete_details for more info.

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 maxium of 512 characters long.

The ID of the Model to be used to execute this run. If a value is provided here, it will override the model associated with the assistant. If not, the model associated with the assistant will be used.

Whether to enable parallel function calling during tool use.

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_object" } enables JSON mode, which guarantees 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.

If true, returns a stream of events that happen during the Run as server-sent events, terminating when the Run enters a terminal state with a data: [DONE] message.

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.

If no thread is provided, an empty thread will be created.

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.

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.

Override the tools the assistant can use for this run. This is useful for modifying the behavior on a per-run basis.

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.

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

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

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

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

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

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

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

The identifier, which can be referenced in API endpoints.

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

The instructions that the assistant used for this run.

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

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

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

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 maxium of 512 characters long.

The model that the assistant used for this run.

The object type, which is always thread.run.

Whether to enable parallel function calling during tool use.

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

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.

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

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

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

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.

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

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

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.).

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

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