Federal Judge Vince Chhabria has ruled in favor of Meta over the 13 book authors who sued the company for training its large language model on their published work without obtaining consent.

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.

A federal judge sided with Facebook parent Meta Platforms in dismissing a copyright infringement lawsuit from a group of authors who accused the company of stealing their works to train its artificial intelligence technology.
