I’m viewing this on a mobile device so I can’t zoom in too efficiently to do all the subtle detail stuff. What I caught onto was the real photos were subtly messy with imperfections. The AI ones have this idealized look to them that has a slight airbrushed effect in aggregate. If people’s faces had blemishes or imperfect skin it’s more likely real. Somehow those imperfections get chopped in AI, probably because they’re so idiosyncratic they don’t survive the AI transformations which look at features en masse.



Even a person wearing glasses messes up with the A.I., look at the image on the left:

And the person on the right here looks airbrushed though. So this might be a closer call with another image.

ON a bigger screen, I would say in the AI ones, the fake hair is "subtly messy with imperfections" - it's a bit like a weave or rug in places, not correctly modelling strands.
