Input

Field	Kind	Default	Description
`prompt` required	text	—	Music description: style, mood, vocals, instrumentation and arrangement. For precise control use a Structured Caption with global metadata (genre, BPM, key, emotional progression), vocal details, and a section-by-section arrangement.
`lyrics` required	text	—	The lyrics to sing. Structure tags such as [intro], [verse], [pre-chorus], [chorus], [post-chorus], [bridge], [instrumental], [solo] and [outro] must each be on their own line; text on the same line as a leading tag is dropped by the model's input contract.
`duration`	number 1 to 300	60	Upper bound on the generated audio length in seconds. The model may stop earlier; the actual duration is returned in the output.
`seed`	number (whole)	—	Random seed for reproducibility. If not provided, a random seed will be used.
`num_inference_steps`	number (whole) 1 to 100	30	Number of flow-matching Euler steps per 8-second denoising chunk. More steps improve quality at the cost of speed.
`guidance_scale`	number 0 to 20	1.7	Classifier-free guidance scale of the flow-matching stage.
