On December 27, 2023, The New York Times filed the first major publisher lawsuit against OpenAI and Microsoft, alleging that ChatGPT and Bing Copilot regurgitate entire NYT articles verbatim when prompted — including a 1,153-word strategy guide for Wordle that the suit reproduces side-by-side. The Times seeks billions in damages and, critically, 'destruction of all GPT or other LLM models and training sets' that incorporated NYT works. OpenAI responded by admitting it had briefly had access to NYT content but arguing fair use. In March 2025 a judge allowed the core copyright claims to proceed. It's now the bellwether case that will define whether training LLMs on copyrighted text is legal.
