This is highly suspected of being gen-AI: https://x.com/hive_ai/status/2036607423126138969

The fact that this account pumps out images of similar "quality" on a daily basis lines up with this suspicion.

Dimensions being 1536px is a red flag, indicating an upscale from 1024px (standard size for gens.), though modern IL finetunes can also handle 1536px genning, The way sweat and hair strands on her left breast seem to line up also makes me think of a model mixing the two up. At the very least, I wouldn't be surprised if this guy sketches over a generated base.
