The system orchestrates multiple AI models—including NotaGen for notation, ACE-Step for audio, and DiffSinger for vocals—to produce commercially-safe, production-ready music with full user ownership. By running entirely on local hardware with an NVIDIA GPU or CPU, The Muser provides a free alternative to services like Suno and ElevenLabs Music, with all output licensed for commercial use under Apache 2.0 or MIT terms.", "body_md": "**The open-source alternative to Suno and ElevenLabs Music.**\nRun locally.
