FAQ

About Suno Instrumental API

It generates instrumental accompaniment for audio you uploaded to Unifically. You reference clip_id from that upload and describe the backing in Simple or Custom fields.

The model path targets uploaded audio with clip_id, not internal Suno clip ids from the generator. Treat it as upload first, add instrumental second.

Suno Add Instrumental is listed at $0.06 per generation.

Simple sends gpt_description_prompt as a plain language brief. Custom sends prompt for finer grained instrumental direction.
