What’s happening
Authors including Richard Kadrey and Sarah Silverman sued Meta over the use of their books to train the Llama models. In June 2025 the court granted summary judgment for Meta on fair use, but framed the decision narrowly — emphasizing that the authors had not shown market harm rather than broadly endorsing AI training. The reasoning left the door open for stronger cases with better evidence.
