Suno sub-models

Nine routes share this page — music generation plus a stack of post-production tools (extend, cover, vocals, instrumental, stems, lyrics, WAV export, sound effects, voice creation). Pick the route that matches the job. Inline custom-model training is available as an option on every route that supports the mv parameter.
