Five publishing houses and author Scott Turow sued Meta and Chief Executive Mark Zuckerberg on Tuesday, alleging the company illegally used millions of copyrighted works to train its AI language system, Llama.

The class action lawsuit, filed in federal court in Manhattan, accuses the tech giant of copyright infringement and opens up a new front in the ongoing battle between the book community and developers of AI.

The plaintiffs allege that Zuckerberg and Meta "followed their well-known motto 'move fast and break things'" by illegally drawing upon a massive trove of books and journal articles for Llama.
