Producing art with an AI requires coming up with a good concept and having the criteria to curate the output

It’s helpful, but as you mentioned by no means necessary. I made this by literally just pasting in the caption from one of the images in the training data. It was trying to see how close I can get to replicating the training data by using a literal caption from it. Well, turns out you can’t, and you’ll just get a gorgeous novel image that bares no resemblance to the original image. The same prompt will give you an infinite amount of permutations so if you don’t care about a specific artistic vision you can just reroll until you get something nice.

Even just typing “by Greg Rutkowski” will get you great results that are completely novel every time.
