Newly released court filings in the Authors Guild's lawsuit against OpenAI and Microsoft reveal that executives and employees at both companies knowingly broke the law by using copyrighted books to train their AI models. The filings show that OpenAI and Microsoft were aware of the potential damage to authors and the book industry, but chose to proceed with their plans anyway. The lawsuit alleges that OpenAI and Microsoft illegally trained their products on copyrighted books, and the new filings provide evidence of the companies' intentional actions.
