Encyclopedia Britannica and Merriam-Webster sued the ChatGPT maker, accusing it of copying almost 100,000 articles to train its AI models

"Encyclopedia Britannica and its subsidiary Merriam-Webster have filed suit against OpenAI, alleging that the ChatGPT maker copied their copyrighted content without authorization to train its large language models,

The lawsuit, filed in Manhattan federal court last week, alleges that OpenAI used close to 100,000 Britannica articles to train its models, and that ChatGPT responses frequently reproduce or closely paraphrase Britannica's reference content, including encyclopedia articles and dictionary entries. The complaint also alleges OpenAI uses a retrieval-augmented generation system to pull from Britannica's content in real time when generating responses."
