Judge rejects most ChatGPT copyright claims from book authors

A US district judge in California has largely sided with OpenAI, dismissing the majority of claims raised by authors alleging that large language models powering ChatGPT were illegally trained on pirated copies of their books without their permission.

By allegedly repackaging original works as ChatGPT outputs, authors alleged, OpenAI's most popular chatbot was just a high-tech "grift" that seemingly violated copyright laws, as well as state laws preventing unfair business practices and unjust enrichment.

According to judge Araceli Martínez-Olguín, authors behind three separate lawsuits—including Sarah Silverman, Michael Chabon, and Paul Tremblay—have failed to provide evidence supporting any of their claims except for direct copyright infringement.

While the Copyright Office prepares to release three reports this year "revealing its position on copyright law in relation to AI," according to The New York Times, OpenAI recently made it clear that it does not plan to stop referencing copyrighted works in its training data. Last month, OpenAI said it would be "impossible" to train AI models without copyrighted materials, because "copyright today covers virtually every sort of human expression—including blogposts, photographs, forum posts, scraps of software code, and government documents."

According to OpenAI, it doesn't just need old copyrighted materials; it needs current copyright materials to ensure that chatbot and other AI tools' outputs "meet the needs of today's citizens."
