Bloomberg’s Hannah Miller and Dina Bass reported that Microsoft is the large tech company that has a licensing deal with HarperCollins for nonfiction books to train AI models, “according to a person familiar with the matter.” That person indicates, “Microsoft wants the HarperCollins books for a model that it hasn’t yet announced…. The company isn’t planning to use the content to generate new books without human authors, the person said.” Some authors and agents had expressed reservations about licensing their content to an unknown entity, potentially concerned about legitimizing a company already known to have directly stolen people’s content.
