Unsealed Briefs in Authors’ Case v. Microsoft/OpenAI
Newly unsealed briefs in Authors Guild v. OpenAI/Microsoft reveal internal communications showing executives and employees allegedly knew they were training on copyrighted books sourced from a 'sketchy Russian website' and understood their products would cause job losses. The filings add to a growing evidentiary record in the ongoing authors' copyright suit against both companies.
Why it matters This is among the most consequential AI copyright cases in the US, and internal admissions of knowingly using pirated training data could weaken the industry's fair-use defenses across dozens of similar suits. A finding against OpenAI/Microsoft could force retraining, licensing renegotiations, or damages that reshape how all major labs source training data going forward.
What to watch Watch for OpenAI and Microsoft's formal response to the unsealed evidence and whether the judge allows the 'knowledge of illegality' claims to proceed toward trial or summary judgment.
