Summary
John Carreyrou and five other authors sued OpenAI, Inc., alleging their books were used to train AI models without permission as part of a broader omnibus copyright lawsuit originally filed against Anthropic, Google, Meta, xAI, and Perplexity.[1][2][3][4] The case invokes copyright infringement claims under federal law; filed December 22, 2025 in NDCA, Carreyrou v. OpenAI was severed by Judge Thompson on joint stipulation in February 2026 for transfer to MDL litigation, likely to be stayed pending fact discovery.[1][2] It challenges AI training on pirated books following an Anthropic settlement authors deemed inadequate, potentially spawning separate suits against each defendant if fully severed.[2][4]
