I am using Stable Diffusion, testing different materials, sculptors, and eras in the prompts. I suppose eventually there will be 3D modelling AI - there are several projects already - but it may be many years before such tech is accessible to hobbyists.
   
   
   
   
   
   
   
   
   
   

Imperfect yes but good enough to share. Not shown are the worst AI mistakes - extra limbs and hands, blemishes, testicles etc! Exploring AI art in this way will take you far into the uncanny valley. But for me the trip is worth it.

Those are amazing! I just started messing with AI art and was trying to make images like this

There's already 3d modeling AI for stable. I don't remember what it's called tho.
