OpenAI now tries to hide that ChatGPT was trained on copyrighted books, including J.K. Rowling’s Harry Potter series::A new research paper laid out ways in which AI developers should try and avoid showing LLMs have been trained on copyrighted material.
Just adding, that, outside of Rowling, who I believe has a different contract than most authors due to the expanded Wizarding World and Pottermore, most authors themselves cannot quote their own novels online because that would be publishing part of the novel digitally and that’s a right they’ve sold to their publisher. The publisher usually ignores this as it creates hype for the work, but authors are careful not to abuse it.
