New Filings in Authors Guild v. OpenAI Reveal Executives Long Knew Mass Pirated-Book Training Was Illegal
On September 21, 2026, plaintiffs in the Authors Guild v. OpenAI lawsuit filed briefs revealing that OpenAI and Microsoft executives and employees intentionally used pirated books from LibGen to train models, aware their products could replace human writers.
