Input Schema

7 parameters · 1 required · 6 optional

Parameter	Type	Required	Description
`prompt`	string	Required	Text prompt to send to the model. English only. · Min length: 1
`audio`	string	Optional	URL of the audio clip to reason about. wav or mp3, max 1 hour.
`top_p`	number	Optional	Nucleus sampling probability mass. · Min: 0 · Max: 1 · Default: 0.95
`max_tokens`	integer	Optional	Maximum number of tokens to generate. · Min: 1 · Max: 20000 · Default: 1024
`temperature`	number	Optional	Sampling temperature. Lower is more deterministic. · Min: 0 · Max: 2 · Default: 0.7
`system_prompt`	string	Optional	Optional system prompt to steer the model. Reasoning behavior is controlled by the separate `reasoning_mode` field.
`reasoning_mode`	string	Optional	Whether the model should emit an explicit reasoning trace. `no_think` returns a direct answer; `think` returns chain-of-thought followed by the final answer. · Options: think, no_think · Default: "no_think" thinkno_think

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response
