There is a limited amount of creativity, but a properly “creative” AI, should not keep repeating the same design pattern over and over.
It’s generative AI, not magic. Repeating the patterns it was trained on is what it was designed to do, even if those patterns aren’t always entirely obvious.
I think the model has been overfitted on its training set, but you can’t expect the types of generative AI we have today to be creative.
