I find it interesting that the AI used to produce the faces at https://thispersondoesnotexist.com/ are so good yet the teeth in the images are usually the only part that looks off, sometimes its really bad. I can always identify it as fake from the teeth where the rest of the face looks real.

Odd because you would think the teeth would be the easy part,.

@freemo Everytime this page gets posted I have to mention the, uh, better version: https://www.thiswaifudoesnotexist.net/ .

More to the point, I suspect because teeth are so simple it's easier to notice that the texture is wrong. Looking at a couple of generated faces I was able too notice weird artifacts on the skin in some cases, but they were much harder to notice than the teeth (if they were wrong).
