YuE2

Moved from Week 37 2026, where it was covered from the project page. The weights are now downloadable: lyrics and a style prompt become a full song with vocals and accompaniment through an AR-NAR mixture-of-transformers backbone writing score and semantic tokens, with flow matching for the acoustic latents, plus cover-song generation via melody transcription. Runs locally on a 24GB GPU in BF16 without quantisation, licensed CC BY-NC 4.0 so non-commercial only. On WildSongBench it reports 6.9632 best-of-8 against Suno v5 at 6.8721 and v6 at 6.5562. One caution: the repo is named YuE2-3B but its own tensor spec says 4B, so treat the parameter count as unsettled.
