The story
Newly unsealed court briefs in the Authors Guild case against Microsoft and OpenAI have revealed specific allegations of copyright infringement related to AI model training. The documents, made public on September 28, 2026, outline claims that the defendants allegedly used protected literary works without authorization to develop large language models. Plaintiffs argue this practice exceeds fair use protections and demands compensation for rights holders. Microsoft and OpenAI have previously denied wrongdoing, maintaining their training methodologies comply with copyright law. The unsealing provides the first detailed public view of evidentiary arguments in this landmark litigation. Legal experts suggest the case outcome may define permissible data usage standards for the entire generative AI sector.
