So did I. I've played around with some local AI models via comfyui before, most are able to take static images and create realistic videos, but never with good sound. So I just assumed that was what he did.
I have some credits with a service that uses the AI model he mentioned. So tested some stuff out, if you use text to video and use any of her cam names it just generates "generic AI woman".
HOWEVER.... gave it an image, gave it a phrase to say... no word of a lie it sounds and moves just like her. It's creepy how realistic it is. I won't be posting it publicly, because AI generated stuff of real people is, to me, a real dark gray area.
So I actually don't think BS at all. Which is scary.
