Sony and UMG are suing Suno again

Sony and Universal Music Group have filed a new lawsuit against Suno, alleging that its latest AI music model, v6, infringes copyrights by being trained on outputs from earlier models that used unlicensed music. The labels accuse Suno of "model laundering," claiming the new model perpetuates copyright violations despite Suno's claims of retraining with new data including user creations.
