Sony and UMG accuse Suno of model laundering with v6

sony and universal music group have filed another lawsuit against suno, alleging that its v6 model infringes on their copyrights. according to the complaint, v6 was trained on user outputs from previous models, which were themselves trained on unlicensed music ripped from youtube and other sources. sony and umg accuse suno of 'model laundering,' claiming that training a new model on the outputs of an infringing model does not eliminate the infringement. suno's v6 model was launched with claims of being 'trained from the ground up, with a new set of data,' including user data. however, sony alleges that suno used distillation to train v6, replicating the results of its previous, 'teacher' models created with infringing data. this lawsuit affects the music industry's approach to ai-generated music and copyright laws.
