A federal judge on Wednesday 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.

A federal judge sided with Meta in a lawsuit that alleged the company had illegally trained its AI models on copyrighted works.

A federal judge ruled that Meta ‘s unauthorized use of copyrighted works from Sarah Silverman and other authors to train generative AI models is a “fair use,” but warned that the practice may in many circumstances be illegal.
