Human-drawn "deformities" are things like super-long legs, missing noses, or mouths so wide they look like a Muppet.
This AI creates tumor-like deformities, where limbs are missing or melded together. As an example, here's an image that couldn't decide if it wanted the girl to have a large chest or a dislocated shoulder: https://thisanimedoesnotexist.ai/results/psi-0.8/seed9182.pn...
This problem is famously solved by Progressive GANs - which are trained with images of increasing size, starting from very small; it helps eliminate the deformities by learning shape at multiple scales.
This is where the AI needs to be trained on the "attractiveness" of different deformities (of course this will depends whether you are aiming for something weird looking or not)
