There are other things models are using AI for too, but to do with planning and organization behind the scenes. So I won't get into that.
Sometimes on my streams I joke about being an AI when guys start treating me inhuman. It's more sarcasm though, spoken to make a wry point. There are no actual 3D AI or cam Robot models, existing in the meat world ... Yet
Did you guys see that movie ? It was craaaazy. Ex Machina (2014). Then there's another one about this batshit rich fucker who clones his gf 8 times (Elizabeth Harvest) but ex Machina is way better. Sorry, total tangent. OP you may or may not want to watch those, I could see them freaking some people out a bit. If you are worried cam models are robots, maybe best to avoid those movies actually.
