The Chicago Sun-Times newspaper published a “Summer Reading List” on Sunday that probably raised quite a few eyebrows in Chicagoland over the weekend. That’s because many of the books on the list are fake. And, predictably, that’s because the list was created with artificial intelligence, a tool that will often just invent things out of thin air.

Those books that the Chicago Sun-Times recommended reading this summer? You can stop looking for them. The newspaper said Tuesday that several of the titles had been generated by AI and don’t actually exist.
