The most difficult things that I usually fail cathastrophically in trying to do with AI:
- persistent girls. Trying to create an AI-girl and re-use her. I really have no idea how to do it.
- fantastic creatures. Since the algorythm usually tries to filter out unhuman features (three arms, etc), it's very hard to force it to generate things like winged angels, mermaids, centaurettes, three-breasted women, four-armed women (from Edgar Rice Burrough's Mars series), nagas (half-snake, half-women), etc.
- implied nudity. Hairbras, handbras, panties shoved into pussy parting lips, etc.
- partial nudity. Open shirts, cleavage or overall jeans showing nipples, miniskirts without panties showing pussy, etc.
- two or more people acting together. Cunnilingus, fellatio, strap-on fuck, hardcore, DP, etc.
I've seen some people posting some of these in this thread. It would be nice if they posted the prompt (and site, etc) used to generate them...
