Meta used copyrighted books for AI training despite lawyers’ warnings, allege authors

Meta Platforms’ lawyers had warned it about the legal perils of using thousands of pirated books to train its AI models, but the company did it anyway, according to a new filing in a copyright infringement lawsuit initially brought this summer.

The new filing late on Monday night consolidates two lawsuits brought against the Facebook and Instagram owner by comedian Sarah Silverman, Pulitzer Prize winner Michael Chabon and other prominent authors, who allege that Meta has used their works without permission to train its artificial-intelligence language model, Llama.
