Key fair use ruling clarifies when books can be used for AI training
Artificial intelligence companies don't need permission from authors to train their large language models (LLMs) on legally acquired books, US District Judge William Alsup ruled Monday.
The first-of-its-kind ruling that condones AI training as fair use will likely be viewed as a big win for AI companies, but it also notably put on notice all the AI companies that expect the same reasoning will apply to training on pirated copies of books-a question that remains unsettled.
In the specific case that Alsup is weighing-which pits book authors against Anthropic-Alsup found that "the purpose and character of using copyrighted works to train LLMs to generate new text was quintessentially transformative" and "necessary" to build world-class AI models.
