Publishers including Elsevier Inc., Cengage Learning Inc., and Hachette Book Group Inc. filed a class-action lawsuit against Meta Platforms. The complaint, filed in the US District Court for the Southern District of New York, alleges Meta used copyrighted books without permission to train its Llama generative AI models.
The lawsuit characterizes the action as one of the largest copyright infringements in history. Plaintiffs claim Meta created unauthorized copies of their works and illegally removed copyright management information during the training process. This case joins a growing wave of litigation from content owners against AI developers, increasing legal and financial risks for the sector.
