Meta's victory came two days after Claude maker Anthropic won a similar case.

“The Court has no choice but to grant summary judgment to Meta on the plaintiffs’ claim that the company violated copyright law by training its models with their books,” wrote US District Court judge Vince Chhabria. He concluded that the plaintiffs did not present sufficient evidence that Meta’s use of their books was harmful.

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.
