The New York Times 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. "We're hopeful that we will find a mutually beneficial way to work together, as we are doing with many other publishers," an OpenAI spokesperson added. "There is nothing 'transformative' about using The Times' content without payment to create products that substitute for The Times and steal audiences away from it," the lawsuit alleged. The lawsuit also said that content generated by ChatGPT and Copilot closely mimicked New York Times style, at times falsely citing the paper as a source, and that its output was given a privileged status by OpenAI because of its reliability. Hundreds of news publishers meanwhile have used programming code to block OpenAI, Google and others from scanning their websites for training data.
