Microsoft has reached an agreement with HarperCollins Publishers to use selected nonfiction books for training artificial intelligence models, as reported by Hannah Miller and Dina Bass for Bloomberg News. The deal allows Microsoft limited access to HarperCollins’ backlist titles, with authors having the option to opt out. The technology company plans to use the content for an unannounced AI model but has confirmed it won’t generate new books without human authors. This agreement joins a growing trend of AI companies securing legitimate content sources, following similar deals between technology firms and major publishers. HarperCollins emphasized that the arrangement includes protective measures for authors’ rights and revenue streams. The partnership emerges amid ongoing tensions between AI companies and publishers, with some, like The New York Times, pursuing legal action over unauthorized content use.
