The NYT sued ChatGPT-maker OpenAI and Microsoft in a US court on Wednesday, alleging that the companies' powerful AI models used millions of articles for training without permission.Through their AI chatbots, the companies "seek to free-ride on The Times's massive investment in its journalism by using it to build substitutive products without permission or payment," the lawsuit said. With the suit, the New York Times chose a more confrontational approach to the sudden rise of AI chatbots, in contrast to other media groups such as Germany's Axel Springer or the Associated Press that have entered content deals with OpenAI.
