real time animatediff?

Went to a party yesterday where the VJ was showing obviously AI generated imagery and I was left wondering wether there was any real time video generating AIs available. It went on for hours and I don't remember having seen again anything that I had already seen but of course I could have missed it, or maybe the VJ could have rendered many hours and just played around with the videos on their VJing software. Anyway, wanted to know if there are any real time software available or what could have been going on :)
