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.” Harper Collins had said previously in a statement that their licensing deal authorized “limited use of select nonfiction backlist titles for training AI models to improve model quality and performance.”
