Scott Nover writes: “In July, a group of writers including comedian Sarah Silverman and novelist Michael Chabon filed suits against OpenAI and Meta, alleging that the companies improperly trained their models on the authors’ books. But one smaller squabble is already headed to trial, and may portend whether authors have a legitimate claim of wrongdoing. In 2020, the media company Thomson Reuters sued a little-known firm called Ross Intelligence. Reuters alleged that Ross tried to license its legal summaries to train an artificial intelligence–powered legal search engine. A trial is tentatively scheduled for May 2024.”
