tl;dr: Unsealed filings in Authors Guild v. OpenAI reveal that OpenAI and Microsoft executives knowingly trained GPT models on pirated books from LibGen, with Microsoft aware of the practice as early as 2019. Internal communications show employees worried about "optics" rather than legality, discussed "autocompleting" George R.R. Martin's series, dismissed author complaints as "acceptable economic disruption," and launched "Project Clear" in 2022 to delete LibGen files and scrub mentions from internal systems. A hearing is expected in early 2027.
