Runs (v1)Legacy
Represents an execution run on a thread.
Related guide: Assistants
Create run (v1)Legacy
Create a run.
Request body
The ID of the assistant to use to execute this run.
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.
Overrides the instructions of the assistant. This is useful for modifying the behavior on a per-run basis.
Appends additional instructions at the end of the instructions for the run. This is useful for modifying the behavior on a per-run basis without overriding other instructions.
Adds additional messages to the thread before creating the run.
Override the tools the assistant can use for this run. This is useful for modifying the behavior on a per-run basis.
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.
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.
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.
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.
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 complete. See incomplete_details for more info.
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 complete. See incomplete_details for more info.
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 a tool.
Specifying a particular tool like {"type": "TOOL_TYPE"} or {"type": "function", "function": {"name": "my_function"}} forces the model to call that tool.
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.
Returns
A run object.

}The run object (v1)Legacy
Represents an execution run on a thread.
The ID of the thread that was executed on as a part of this run.
The ID of the assistant used for execution of this run.
The status of the run, which can be either queued, in_progress, requires_action, cancelling, cancelled, failed, completed, or expired.
Details on the action required to continue the run. Will be null if no action is required.
The last error associated with this run. Will be null if there are no errors.
Details on why the run is incomplete. Will be null if the run is not incomplete.
The model that the assistant used for this run.
The instructions that the assistant used for this run.
The list of tools that the assistant used for this 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 maximum number of prompt tokens specified to have been used over the course of the run.
The maximum number of completion tokens specified to have been used over the course of the 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 a tool.
Specifying a particular tool like {"type": "TOOL_TYPE"} or {"type": "function", "function": {"name": "my_function"}} forces the model to call that tool.
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.

}The run step object (v1)Legacy
Represents a step in execution of a run.
The ID of the assistant associated with the run step.
The ID of the thread that was run.
The ID of the run that this run step is a part of.
The status of the run step, which can be either in_progress, cancelled, failed, completed, or expired.
The last error associated with this run step. Will be null if there are no errors.
The Unix timestamp (in seconds) for when the run step expired. A step is considered expired if the parent run is expired.
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.
