API Parameters

Name	Type	Default	Description
`include_reasoning`	boolean	—	Include the model's internal reasoning trace in the response.
`max_tokens` deprecated	integer	—	Deprecated. Use max_completion_tokens.
`reasoning`	object	—	Configuration for extended-thinking / reasoning mode.
`stop`	array	—	Up to 4 sequences where the API will stop generating tokens.
`temperature`	number	1	Sampling temperature; higher values produce more random output. 0 is deterministic.
`tool_choice`	one of	—	Controls which (if any) tool is called: "none", "auto", "required", or a specific tool.
`tools`	array	—	List of tools (functions) the model may call.
`top_k`	integer	—	Limit sampling to the top-k most likely tokens at each step.
`top_p`	number	1	Nucleus sampling: consider only tokens whose cumulative probability ≥ top_p.

Standard OpenAI-compatible parameters. Consult the provider docs for model-specific behaviour.
