A coalition of copyright law professors has filed an amicus brief supporting authors in a lawsuit against Meta, accusing the tech giant of unlawfully training its Llama AI on copyrighted ebooks. The brief challenges Meta's fair use defense, asserting that such training is not transformative and serves commercial purposes that compete with original works. Prominent authors like Richard Kadrey and Sarah Silverman claim Meta infringed their intellectual property by using their works without permission. The case, Kadrey v. Meta, continues in the U.S. District Court, raising significant questions about AI and copyright law.
