Request body

7 properties · 2 required · 0 $defs

property	type	description	constraints
prompt*	string	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*	string	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.
enable_safety_checker	boolean	Authorized callers may set false to request relaxed screening.	default: true
duration	number	Upper bound on the generated audio length in seconds. The model may stop earlier; the actual duration is returned in the output.	1 ≤ n ≤ 300 · default: 60
num_inference_steps	integer	Number of flow-matching Euler steps per 8-second denoising chunk. More steps improve quality at the cost of speed.	1 ≤ n ≤ 100 · default: 30
guidance_scale	number	Classifier-free guidance scale of the flow-matching stage.	0 ≤ n ≤ 20 · default: 1.7
seed	integer	Random seed for reproducibility. If not provided, a random seed will be used.	nullable
