Paramount Issues Cease-and-Desist to ByteDance Over AI Training
Paramount has demanded that ByteDance stop using its intellectual property to train and power generative AI models, naming Seedance and Seedream, and alleges the models were trained on copyrighted material without consent. The complaint claims AI outputs are "often indistinguishable" from franchises such as South Park, Star Trek and The Godfather. The move follows a similar legal threat from Disney and coincides with industry pushback after the release of Seedance 2.0. Trade groups including the Motion Picture Association and the Human Artistry Campaign have criticized ByteDance, and actors’ union SAG‑AFTRA has raised concerns about unauthorized use of celebrity likenesses. The dispute challenges the tech industry's common "fair use" defense and could set a legal precedent affecting how generative AI models are trained on creative works.
A major studio's legal action against a large tech platform could set precedent on whether generative AI models may be trained on copyrighted creative works without permission, affecting data practices, licensing costs, and legal risk across AI, media and advertising industries.
