If this means you can ask it to pretend to be a busty nurse with a limp, that already exists. If it means that you can say “what’s the name of that video with the busty nurse with a lisp?” and it’ll give you a link, then that’s potential, right there. I can imagine them right now torrenting every porn video they can and getting one llm to transcribe it to create training data for another llm while a third llm does image/scene analysis.
