What stands out

What its maker marketed at launch, and what people found later, each with its source.

  • Hybrid LLM-diffusion full songs up to 4:30

    4B-parameter model generating complete songs up to 4 min 30 s with vocals + accompaniment, instrumental-only, a cappella or dual-track (separated) output; multilingual lyrics (Chinese, English, Spanish, Japanese and more).

    Source: github.com

  • Hierarchical semantic planning + track-specific refinement

    Found after launch

    LeVo 2 paper: semantic planning precedes per-track refinement to keep vocal-instrument coordination while improving acoustics; progressive post-training with automatic quality tiers.
