Meta on Wednesday won a motion for partial summary judgment in its favor in Kadrey v. Meta, a case brought on by 13 authors alleging the company infringed on their copyright protections by illegally using their books to train its Llama AI models.

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.

It is the second legal victory for AI tech companies in a week after a US court ruled Anthropic had not breached copyright by training its artificial intelligence large language model Claude on authors’ work.
