On illuminarty.ai i find this tool that detect AI generated images, synthetic, tampered images and Deepfake. There’s a Free version and some subscription plan. After a couple of test it actually showed somewhat accurated results:
.> 70% Chance on actual AI drawing tested
<20% On (human) edited images
<5% On original handmade drawings
EDIT - Not so great with realistic AI Photo. Somehow works better with AI art.

So, this picture of a lemming putting its hand in a bean soup in a beautiful mountain scenery has an probability of being AI of 0.1%. Seems legit.
