Sony and UMG are suing Suno again

Sony and Universal Music Group have filed a fresh lawsuit against Suno, alleging that its new v6 model infringes on copyrights. The labels claim that v6 was trained on outputs from previous models, which were themselves trained on unlicensed music ripped from platforms like YouTube. The labels accuse Suno of "model laundering," arguing that training a new model on the outputs of an infringing one does not eliminate the infringement but merely transfers it. While Suno maintains that v6 was trained on licensed content and user interactions, it has not provided specific details regarding whether uploaded audio was included in the training set. Sony further alleges that Suno utilized distillation to train v6 to replicate the results of its previous, infringing models. The labels contend that unless Suno builds its models from scratch, they will continue to benefit from unauthorized copies of copyrighted material.
