Nonfiction Authors Sue OpenAI, Microsoft for Copyright Infringement

OpenAI and its financial backer Microsoft were sued in Manhattan federal court by a pair of nonfiction authors who say the companies misused their work to train the artificial-intelligence models behind the popular chatbot ChatGPT and other AI-based services. Writers Nicholas Basbanes and Nicholas Gage told the court in a proposed class action that the companies infringed their copyrights by including several of their books as part of the data used to train OpenAI's GPT large language model.
