On December 22 (local time), a coalition of authors, spearheaded by John Carreyrou—a double Pulitzer Prize laureate in journalism—initiated a copyright infringement lawsuit in the United States District Court for the Northern District of California. The legal action targets six major AI entities: Anthropic, Google, OpenAI, Meta, xAI, and Perplexity AI. The writers allege that these companies utilized unauthorized copies of their literary works to train extensive language models, an act they characterize as "willful theft."
