Five major publishing houses and author Scott Turow file a class-action lawsuit against Meta and CEO Mark Zuckerberg, alleging they used copyrighted works without permission to train Meta’s generative AI models, including the Llama system. The plaintiffs, including Elsevier, Cengage Learning, Hachette, Macmillan, and McGraw Hill, claim Meta illegally copied millions of books, journal articles, and other content and downloaded material they describe as pirated, then used it to train AI. Several reports say the complaint alleges Zuckerberg “personally authorized and actively encouraged” the conduct, including that he directed Meta to proceed without licensing copyrighted materials. The lawsuit is filed in U.S. District Court for the Southern District of New York and seeks monetary damages, though the reports describe the amount as unspecific. Meta denies the allegations and says it will fight the case. The company argues that AI training on copyrighted material may be covered by fair use, and points to legal precedents that it says support that position.
