Look for artifacts in hands, texts, and also look for incoherence among distant sections.
Got 27 out of 30 in first try.

Re: Show HN: Can you tell if an image is AI-generated?
#33I was looking for tells, but things like landscapes or pictures where there's no hands or eyes tend not to have them as much.
Hands definitely, AI doesn't seem sure if a hand ought to have 0 1 or 2 thumbs, and it's also unclear how fingers work.
I haven't noticed big problems with eyes.
AI doesn't really seem to understand how boobs work, but human artists (presumably especially male artists?) don't seem to understand how boobs work either so it isn't a tell.
Today's AI doesn't understand how text works, several images I was shown had human text which made sense in context and therefore must be human made (e.g. a scene of an office front with a car having a plate with number in the form AA99 AAA, that's how plates work in the UK an AI has no reason to write AA99 AAA rather than 9A9 99 or whatever), one was trickier because the text was Japanese, and I don't read Japanese - I understand a couple of easy characters but not enough to be sure, I marked it human because the text looked plausible, if I could read Japanese I'd have been confident.
Cliché is in general a hard problem. Is this really obvious trope in the image because the AI just copies what it has seen (in some broad sense) or is it there because human artists also copy what they have seen in some similarly broad sense.

#34It official. Years of programming and on the internet has condition me. I’m good at telling the difference.
This is the saddest moment of my life. I actually can tell the difference between the two images. God Please save me from this miserable existence.

#35To be fair, to me, title should be more like are you able to tell cherry picked AI images from cherry picked human created images, since both clearly were selected to appear similarly picked to confuse a human in my opinion. No idea if that’s accurate, or even if it is, how to fix it, but one idea would be to get a list of the top ten search queries on a popular stock image site, then randomly pick an AI image and hu…
Actually no, they were not cherry picked. Except for generations which did not match the prompt at all, I took every image that was created. For the human images, I just took things from Unsplash's and ArtStation's front pages. I clicked on those images without looking. Early next year I'll do a better quiz with more variety. This was a weekend project.

While I believe I understand what you mean, to me, this is not what AI generated art means, hence why I suggested limiting prompts to existing top queries to a top stock image site and the using that as the prompt. Also, I have to say that I very surprised none of the AI images were cherry picked, since I personally have run 100s if not 1000s of “high quality” prompts, and in my experience volume of misfits is normal pretty high; for sure read and reviewed 1000s of prompts and their outputs which were shared and in my experience even those have artificial artifacts and are likely cherry picked from the ones that were much worse.
Another alternative might be to get the top best selling stock images, run them through CLIP, then use those as the prompts, but then you’re evaluating CLIP + plus whatever AI image generation system you’re using.
Another huge give away is the resolution. Obviously you’re able to get ultra super resolution human generated images, but to my knowledge that’s not possible yet for AI images.
Which AI generation tool were you using and what were the prompts/settings?

#36> You correctly classified 22 of 30 (73%) images!
Probably shouldn't show duplicate images in the same test, as that's just dropping the sample size.
You may want to spell out exactly what you mean by "AI". If someone goes into photoshop and clicks "Edit › Sky Replacement.", it's not quite what I'd call human made.

#37In a few years this will not be possible at all.
Re: Show HN: Can you tell if an image is AI-generated?
#38You correctly classified 27 of 30 (90%) images!
You identified 14 of 14 (100%) AI-generated images.
You identified 13 of 16 (81%) human-made images.
Better than I thought. Got a few dupes though.

Same score here. I think I could have done better if there was less JPEG.

Two models were used for image generation: the not-yet-released AniPlus v2 and vanilla Stable Diffusion 1.5 AniPlus v2 generally creates good if not great images consistently.
All images were generated in AUTOMATIC1111's web UI, with the DPM++ 2S A sampler @ 15 steps. I'll soon release the metadata for the AI images.
