StepFun and ACE Studio present StepAudio 3 Music, StepFun’s first music generation foundation model — built to turn a prompt and lyrics into a complete song.

Describe the sound you want:
• Genre, mood and vocal character
• Instruments, key and BPM
• Song structure and arrangement

Four workflows in one model:
🎤 Song generation
🎹 Instrumental generation
🔁 Music cover
🎙️ Vocal-to-song arrangement

Powered by ABC-COT, it plans musical structure and arrangement before synthesis. Generate a version, rewrite the prompt, edit the ABC notation, and iterate toward the sound in your head.
(ABC-COT API coming soon)
