Sony and Universal Music Group file new copyright lawsuit against Suno over v6 model
Lawsuit filed
Sony and Universal Music Group filed another lawsuit against AI music company Suno, alleging that its new v6 model continues to infringe their copyrights. The labels claim the v6 model was trained on user outputs from previous models that were themselves trained on unlicensed music ripped from YouTube and other sources, accusing Suno of 'model laundering,' and further allege Suno used distillation to replicate results of earlier infringing 'teacher' models. Suno said v6 was trained on licensed content, user community interactions and creations, and its team's accumulated learnings.
Company response
Clarification — Suno
Suno spokesperson Rachel Racusen later confirmed to The Verge that data includes “creations” from users, saying, “v6 was trained on content licensed from our partners, interactions including creations and preference signals from our community, and the accumulated learnings from our team,”
Denial — DistroKid
We strongly dispute the allegations underlying UMG’s lawsuit and regret the disruption to affected artists.
