ByteDance's AI video generation model Seedance 2.0 went viral after producing hyper-realistic celebrity deepfake videos, prompting cease-and-desist letters from Paramount and Disney — who accused the TikTok parent company of using their intellectual property to train the model — and condemnation from the Motion Picture Association and SAG-AFTRA. ByteDance pledged to strengthen IP safeguards and rolled back a feature allowing realistic audio generation from a user's image. The controversy arrives as China's Cyberspace Administration tightened enforcement against unlabeled AI-generated content, penalizing more than 13,000 accounts, while analysts note Beijing is navigating a difficult balance between promoting domestic AI development and controlling its risks.
