Parameters

Aggregated across active providers for the responses route.

Routing will select a compatible provider when a parameter narrows availability, so this list stays model-facing instead of provider-facing.

View all parameters

Parameter	Description
`temperature`	Controls how random token selection can be.
`top_p`	Applies nucleus sampling by limiting candidates to a probability mass threshold.
`max_tokens`	Caps output length on endpoints and providers that use the max_tokens field name.
`tool_choice`	Controls which tool, if any, the model should call.
`tools`	Defines callable tools or functions the model can invoke.
`parallel_tool_calls`	Allows or restricts concurrent tool execution where supported.
`response_format`	Requests plain text, JSON, or schema-constrained output formats.
`structured_outputs`	Capability signal for reliable schema-constrained output workflows.
`reasoning_effort`	Requests a lower or higher reasoning budget when the endpoint exposes that control.
`web_search_options`	See the full parameter reference for endpoint-specific semantics and provider caveats.
