LeVo 2 framework advances AI song generation with hierarchical modeling

By PulseAugur Editorial · [2 sources] ·

Researchers have developed LeVo 2, a novel hybrid LLM-Diffusion framework designed for generating full-length songs with enhanced coherence and musicality. The system employs a hierarchical modeling approach, with LeLM handling semantic planning and a diffusion-based Music Codec reconstructing waveforms. A key innovation is an aesthetics-guided training schedule that progressively refines generation quality, controllability, and musicality through supervised fine-tuning and various forms of direct preference optimization. AI
