API Parameters

Name Type 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 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_p number Nucleus sampling: consider only tokens whose cumulative probability ≥ top_p.

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