StepFun Releases StepAudio 3 Music Music Generation Foundation Model

StepFun and ACE Studio jointly release StepAudio 3 Music, StepFun's first music generation foundation model, which can generate complete songs from prompts and lyrics. The model integrates four workflows: song generation, accompaniment generation, music cover, and vocal-to-song arrangement. ABC-COT plans the musical structure and arrangement before synthesis, and users can rewrite prompts, edit the ABC notation, and iterate. A Hugging Face Space demo and API documentation are now available, and the ABC-COT API is coming soon.
