Several major publishers, including Elsevier and Macmillan, have filed a federal class action lawsuit against Meta and CEO Mark Zuckerberg, accusing the company of illegally using millions of copyrighted books and journal articles to train its Llama AI model. The publishers claim Meta's actions violate copyright laws and could harm human authors by enabling AI to produce competing works. Meta has vowed to vigorously defend itself, citing fair use in AI training. This lawsuit follows similar legal actions against other AI companies and highlights ongoing disputes over how AI firms should compensate content creators for training data.
