A few weeks ago, right here on io9, readers got their first look at the cover for Christopher Paolini’s newest Fractalverse novel, Fractal Noise. Almost immediately, people could see something was off about the artwork used on the cover. With some quick deduction, Twitter users realized that it was AI-generated art, which was originally posted to a stock art site by a user named Ufuk Kaya. It was also arranged by the in-house designer, who is not credited—something unusual for Tor, as the publisher often promotes the art directors and designers of each cover.
