How we work: https://postcutoff.com/about/ Canonical page: https://postcutoff.com/e/2026-09-09-suno-v6-licensed-music-model/ # Suno launches v6, its first music models trained on licensed music On 2026-09-09 Suno launched the v6 family (v6, v6-wild, v6-mini), trained from scratch on music licensed from Warner Music Group, BMG and Believe with revenue sharing, and retired all older models; Sony Music and Universal sued again on 2026-09-18, alleging v6 was trained on outputs of the old unlicensed models. ## Key facts - Three models: v6 (flagship, paid), v6-wild (more varied, paid), v6-mini (fast, free tier) - Licensing partners: Warner (deal Nov 25 2025, settling its suit), BMG (Aug 12 2026), Believe/TuneCore (Sept 8 2026) - All earlier models (v4 through v5.5) retired on launch day - New features: section editing by prompt/lyrics, text/image/video references, stem separation, opt-in artist remixing - Suno has raised >$819M (PitchBook via TechCrunch) - Sony Music and UMG filed new suit in Massachusetts federal court on 2026-09-18 ## What happened Suno, the largest AI music generator, replaced its entire lineup with a licensed-data model family. Partners receive a share of revenue from launch day and distribute it to rights holders. Suno says v6 was not trained on the data used for earlier versions (which had included YouTube audio). The remaining majors, Sony and Universal, plus artist Jason Isbell, continue to litigate. ## Why it matters v6 is the clearest test yet of a licensed-training business model for generative media; the new Sony/UMG suit tests whether "clean-room" retraining on licensed data (but with learnings from older models) is enough. ## Your AI and this story - GPT-6 Astra (training cutoff April 2026): 132 days after its cutoff - Claude Opus 5.5 (training cutoff June 2026): 71 days after its cutoff - Gemini 4 Hydrogen (training cutoff March 2026): 162 days after its cutoff - Grok 4.7 (training cutoff May 2026): 101 days after its cutoff ## Sources 1.
