Anthropic settles AI book-training lawsuit with authors

Anthropic has settled a class action lawsuit with a group of fiction and nonfiction authors, as announced in a filing on Tuesday with the Ninth Circuit Court of Appeals. Anthropic had won a partial victory in a lower court ruling and was in the process of appealing that ruling. No details of the settlement were made public, and Anthropic did not immediately respond to a request for comment.

Called Bartz v. Anthropic, the case deals with Anthropic’s use of books as training material for its large language models. The court had ruled that Anthropic’s use of the books qualified as fair use, but because many of the books were pirated, Anthropic still faced significant financial penalties for its conduct connected to the case.
