The Globe and Mail reports in its Thursday, Sept. 21, edition that a trade group for U.S. authors has sued OpenAI in Manhattan federal court on behalf of prominent writers including John Grisham, Jonathan Franzen, Michael Connelly, Scott Turow, George Saunders, Jodi Picault and George R.R. Martin, accusing the company of unlawfully training its chatbot ChatGPT on their work. A Reuters dispatch to The Globe reports that the proposed class-action lawsuit filed late on Tuesday by the Authors Guild joins several others from writers, source-code owners and visual artists against generative AI providers. In addition to Microsoft-backed OpenAI, similar lawsuits are pending against Meta Platforms and Stability AI over the data used to train their AI systems. Reuters says representatives for OpenAI did not immediately respond to a request for comment on Wednesday. OpenAI and other AI defendants have said their use of training data scraped from the Internet qualifies as fair use under U.S. copyright law. Authors Guild chief executive officer Mary Rasenberger said on Wednesday that authors "must have the ability to control if and how their works are used by generative AI" in order to "preserve our literature."
