Package version:
OptionaladditionalAdditional instructions to append 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.
OptionaladditionalAdds additional messages to the thread before creating the run.
OptionalincludeA list of additional fields to include in the response.
Currently the only supported value is step_details.tool_calls[*].file_search.results[*].content
to fetch the file search result content.
OptionalinstructionsThe overridden system instructions that the agent should use to run the thread.
OptionalmaxThe 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.
OptionalmaxThe 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.
OptionalmetadataA set of up to 16 key/value pairs that can be attached to an object, used for storing additional information about that object in a structured format. Keys may be up to 64 characters in length and values may be up to 512 characters in length.
OptionalmodelThe overridden model name that the agent should use to run the thread.
OptionalparallelIf true functions will run in parallel during tool use.
OptionalresponseSpecifies the format that the model must output.
OptionalstreamIf 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.
OptionaltemperatureWhat 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.
OptionaltoolControls whether or not and which tool is called by the model.
OptionaltoolsThe overridden list of enabled tools that the agent should use to run the thread.
OptionaltopPAn 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.
OptionaltruncationThe strategy to use for dropping messages as the context windows moves forward.
Optional parameters.
