Udio v1.5 Allegro is a proprietary music generation model designed for high-fidelity audio production with significantly reduced inference times. Released as a distilled optimization of the original v1.5 architecture, the Allegro version provides generation speeds up to four times faster while maintaining 48kHz stereo output and the model's signature musical coherence.
The model excels in instrument separation and vocal clarity, narrowing the gap between AI-generated content and professional studio recordings. It supports advanced creative features such as stem separation (allowing users to isolate vocals, drums, and bass), precise key control, and enhanced support for a wide range of global languages and musical genres.
