Open Source Music AI
The AI music generation landscape has matured rapidly. Meta's MusicGen (MIT license) generates full tracks from text with melody conditioning. Demucs (MIT) provides industry-leading source separation. Bark (MIT) handles text-to-speech with music and singing capabilities. These models are free to deploy commercially.
For higher quality, Stability AI's Stable Audio 2.0 offers a commercial API with superior production quality and longer generation times. The combination of open-source foundation models with commercial APIs provides the ideal stack for a music platform like PromptBeat.
Building a Music Platform
A PromptBeat platform would combine these models into a seamless workflow: text prompt → music generation (MusicGen/Stable Audio) → stem separation (Demucs) → editing and mixing (Tone.js) → export with commercial license. Monthly subscription at $19.99/mo positions affordably for independent musicians.
