Authors’ class action against OpenAI moves forward
A U.S. federal judge has ruled that a class action lawsuit filed by a group of authors, including members of the Authors Guild, can proceed against OpenAI. The authors allege that ChatGPT infringes their copyrights by producing text substantially similar to their original works.
Judge Sidney Stein found that the plaintiffs may be able to demonstrate that ChatGPT’s outputs are close enough in tone, plot, and themes to their books to constitute infringement. The decision allows the case to move ahead but does not address the question of fair use—a U.S. legal doctrine with no direct Australian equivalent.
This follows an earlier class action that authors won against Anthropic, in which the company was found to have used pirated books to train its AI models.
This case is likely to have major implications for how AI systems are trained and how copyright is interpreted in the digital era.
