A federal judge let Meta off the hook for the use of books to train its artificial intelligence model, but it still might face legal challenges by the authors in other ways.

Meta scored a major victory in a copyright lawsuit on Wednesday when a federal judge ruled that the company did not violate the law when it trained its AI tools on 13 authors' books without permission.

Meta just won a major ruling in a landmark case about how copyright law and fair use applies to AI model training, the second such loss for authors this week. Just days ago, Anthropic won a fair use case as well.
