GoKawiilSony and Universal Music Group file new copyright suit against Suno over v6 model
Sony Music and Universal Music Group have sued AI music generator Suno again, alleging its newly launched v6 model still infringes their copyrights. The labels argue v6 was trained on outputs from Suno's earlier models, which themselves relied on unlicensed music, and that this 'model laundering' carries the infringement forward even without direct use of the original recordings.
GoKawiil's interpretation of the reporting above, not reported fact.
The case tests whether AI companies can sidestep copyright claims by training new models on outputs of older, allegedly infringing ones rather than on original copyrighted works directly. Sony and UMG remain holdouts that have not licensed their catalogs to Suno, unlike other labels, so the outcome could shape licensing negotiations and legal standards across the AI music industry. Suno has offered limited detail on its training data, which the labels argue supports their distillation and laundering claims.
- Sony and UMG filed a fresh lawsuit against Suno targeting its v6 model.
- The labels claim v6 was trained via distillation on outputs of earlier infringing models.
- Suno has not signed licensing deals with Sony or UMG and has given limited detail on its training data.
