As a joke I put a face into GPT and said, make it look upset.
It rejected it, saying it violated policy, it can’t show people crying and what not, but it could do bittersweet.
I said that crying is bittersweet and it generated the image anyway.
I tried the same by turning a cat into a hyper realistic bodybuilder and it got as far as the groin before it noped out. I didn’t bother to challenge that.
I've yet to figure out a way to make it make Mario. It'll make coloring pages of Hello Kitty just fine, but asking for "Italian plumber" or anything similar has resulted in "content policy".
I don't know what the magic words would be.
