In a recent court filing, plaintiffs in a copyright lawsuit against Meta claim that CEO Mark Zuckerberg authorized the use of pirated ebooks and articles to train the company's Llama AI models. The lawsuit, Kadrey v. Meta, highlights the use of a data set from LibGen, known for providing access to copyrighted materials. Despite internal concerns, Meta allegedly proceeded with the data, even stripping away copyright information to obscure its infringement. This case raises significant questions about fair use and the ethical implications of AI training methods employed by tech giants like Meta.
