For fun, I took that image and put it into a few models and asked it "what is wrong with this genAI image?"

Grok fast came up with a lot of minor quibbles and missed the issue.

Grok expert touched on it with a "Limbs/anatomy ambiguity / This creates a slight "how many legs does this cat actually have?" moment." but then moved on to complain about texturing . Later it summarized the issue as "classic "animal + held object" anatomy problem".

Chatgpt 5.6 instant didn't notice it

Chatgpt 5.6 medium didn't notice it and mainly complained about the background being blurry

Chatgpt 5.6 high (46s) "The biggest error is the cat appears to have six paws"

Google AI mode complained about whiskers and feet placement

Only chatgpt high and marginally grok expert had acceptable answers.
