(Reuters) - A group of U.S. authors, including Pulitzer Prize winner Michael Chabon, has sued OpenAI in federal court in San Francisco, accusing the Microsoft-backed program of misusing their writing to train its popular artificial intelligence-powered chatbot ChatGPT.

Chabon, playwright David Henry Hwang and authors Matthew Klam, Rachel Louise Snyder and Ayelet Waldman said in their lawsuit on Friday that OpenAI copied their works without permission to teach ChatGPT to respond to human text prompts.
