A federal judge is allowing an AI-related copyright lawsuit against Meta to move forward, although he dismissed part of the suit.

In Kadrey vs. Meta, authors including Richard Kadrey, Sarah Silverman, and Ta-Nehisi Coates have alleged that Meta has violated their intellectual property rights by using their books to train its Llama AI models, and that the company removed the copyright information from their books to hide the alleged infringement.

Meta, meanwhile, has claimed that its training qualifies as fair use, and it argued the case should be dismissed because the authors lack standing to sue. In court last month, U.S. District Judge Vince Chhabria seemed to indicate he was against dismissal, but he also criticizing what he saw as “over-the-top” rhetoric from the authors’ legal teams.
