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.
They can own it, actually. If you use the characters of Bugs Bunny, etc., or the setting (do they have a canonical setting?) then Warner does own the rights to the material you’re using.
For example, see how the original Winnie the Pooh material just entered public domain, but the subsequent Disney versions have not. You can use the original stuff (see the recent horror movie for an example of legal use) but not the later material like Tigger or Pooh in a red shirt.
