Sony and UMG sue Suno again, accusing its v6 model of 'model laundering'

Sony and UMG filed a new lawsuit against Suno. They claim the v6 model was trained on outputs from earlier models, which themselves were trained on unlicensed music ripped from YouTube and other sources. The labels call this 'model laundering' and argue that training a new model on infringing outputs does not erase the original infringement. Sony and UMG are notable holdouts that have not signed a licensing deal with Suno.
