Show HN: Can you tell if an image is AI-generated?
- slicktux 4y agoI got 80%
- BOOSTERHIDROGEN 4y ago93% here
- nashashmi 4y agoOnly if I am looking for it. And I have to look very closely. Some of the tell tale signs of a manipulated image is low resolution material that hides away much of the photoshop stuff.
- gus_massa 4y agoI got a few repetitions, and a few images that were very similar (like in a serie of drawings about the same character). Is the set of images the same for everyone or you are randomizing it?
- ronsor 4y agoThere are a total of ~130 combined human-made and AI-made images. 30 images are selected from that pool at random.
- rwky 4y agoApparently I can't I only got about half right on both sides!
- V__ 4y agoIt would be nice to see the mistakes at the end. Right now, I have a feeling that I misidentified the anime pictures but was good on the nature ones, but I would like to know whether that's actually the case.
- ronsor 4y agoIf you submitted your email address, I'll email you the details next week. If not, then visit the session dump page [1][2] and send me your session ID in an email.

- V__ 4y agoGreat, thank you
- csa 4y ago9/15 ai and 12/15 human with a quick pass through. Interesting challenge.
- Darmody 4y agoI gave up after 2 images and 6 or 7 captchas.
- andrewmutz 4y agoHalf of the time it was asking me captchas so I just gave up
- ronsor 4y agoThe captcha should only appear once per quiz session. Do you have cookies blocked or a similar configuration? Visiting https://aiquiz.ronsor.com/session_dump.jsp https://aiquiz.ronsor.com/session_dump.jsp will show you your session information.
- raylad 4y agoIt keeps asking me to do arithmetic problems to prove I'm not an AI (several in a row) and then loses its place and starts over with #2 (not necessarily the same image).
- zeven7 4y agoI guess the real question isn't "Can you tell if an image is AI-generated?" but "Can the server can tell if guesses are AI-generated?"
- lelandbatey 4y agoI seem to get a LOT of captchas and I seemed to be unable to complete the quiz. I tried again and was able to get an 80% accurate classification rating by racing through before it broke. Quite a fun and interesting quiz!
- rightbyte 4y agoI tried to do the test but I was shown captchas three times in a row multiple times and it reset the test ...
- O__________O 4y ago>> CAPTCHA: In order to prevent bogus quiz submissions and reduce required network resources, please solve the following problem: (add/subtract two number) >> Repeated CAPTCHA prompts, image, repeated CAPTCHA prompts, image, etc. Wow. No idea what is going on, but you managed to make the most unusual and annoying experience I have had on the web ever. Curious, what was your reasoning for doing this?
- ronsor 4y agoThe CAPTCHA is supposed to filter bots. For some reason, the site has a bug keeping track of sessions (it just stops being able to), so as a result, it can't keep track of any quiz data. I restarted the server so it should be working again.
- O__________O 4y agoThanks, fixed it, at least for me.
- layoric 4y agoInsane captchas creates a completely broken experience. Filled out more than a dozen before giving up after being reset multiple times.
- autotune 4y agoYou filled out more than a dozen captchas? I guess if this was a competition, you would be the winner.
- bobsmooth 4y agoI only missed 1 AI image. Look at the hands and eyes, makes it really obvious.
- Kim_Bruning 4y agoI was looking for tells, but things like landscapes or pictures where there's no hands or eyes tend not to have them as much.
- YurgenJurgensen 4y agoSince it didn't tell you what ones you got right, I can't use my 76% as evidence (I got a lot of blurry pictures of forests, which are hard because it's either an AI or a low-effort background art asset), but while landscapes are the hardest, a bunch of obvious tells without hands or eyes (and the other well-known one: text) are: Shoelaces. Or anything where things pass over and under other things. The AIs did really poorly with belt buckles too. Its sense of object permanence is entirely stochastic, and small details don't get a lot of virtual brain power devoted to them. Straight lines and repeating patterns. "Human hand holding a 30cm ruler in front of a chain link fence" is probably AI kryptonite. Symmetry. If there's a nontrivial object that's supposed to be symmetric, chances are, it won't be. Swept curves and perspective. Another thing that's stochastic is the AI's understanding of how 3D spaces map onto 2D images. Circular objects being transformed in 3D, like a roundabout being viewed in perspective, or a curved road moving off into the distance will typically be inconsistent with human expectations. Of course, some of these mistakes are also made by human artists, but generally the human artists who make these mistakes also have amateurish colouring, lines or brushwork, and AIs are generally pretty good at emulating good brushwork.
- tialaramex 4y agoHands 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.
- intelVISA 4y agoGot 80% overall. Hopefully I can live up to Mr. Deckard. Would be cool to see a diff at the end of the ones you were wrong about.
- tannerwj 4y ago73% - wish I could've seen which ones I got right or wrong It will be interesting when we get to a point where we can't tell a difference
- O__________O 4y agoTo 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 human image; problem being that in my experience it would become painful obvious on average which was real and which was AI, which to me points out that AI images as they’re currently “generated” heavily depend on humans to create prompts and curate which are shared. How did you filter, select, etc the images?
- ronsor 4y agoActually 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.
- O__________O 4y ago>> Except for generations which did not match the prompt at all, I took every image that was created. 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?
- qrian 4y agoLook for artifacts in hands, texts, and also look for incoherence among distant sections. Got 27 out of 30 in first try.
- Veedrac 4y agoSame score here. I think I could have done better if there was less JPEG.
- stephc_int13 4y ago66% here
- a3w 4y ago50%. No, I did not toss a coin.
- evilos 4y agoSame. Thought I would get at least 75% honestly.
- stephc_int13 4y agoAnime pictures are very hard to detect because they are artificial no matter what, I am not sure they should be part of the set.
- biggerChris 4y agoIt 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.
- nitwit005 4y ago> 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.
- tommica 4y agoI only had a duplicate cat and thought that it was a trick question
- bhouston 4y agoIn a few years this will not be possible at all.
- zppln 4y agoYou 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.
- boppo1 4y agoToo many similar AI pics. Once I had spotted one anime pic, I got the rest. landscapes were tough though.
- zabzonk 4y agosurely if an AI can generate a "work of art", another AI should be able to detect the generation?
- cal85 4y agoWhy?
- x-complexity 4y ago> You correctly classified 26 of 30 (86%) images! > You identified 12 of 14 (85%) AI-generated images. > You identified 14 of 16 (87%) human-made images. In general, I followed a pretty simple rule: - If it's a photograph, it's likely human if there're no immediate imperfections - If it's an illustration, it's AI if the art has imperfections OR if it's anime-adjacent (example: images with glossy lighting on human skin) Right now, SD-based art is trending towards a particular art style (anime-like & 3D-ish art), with little inherent ability towards creating subtle details in the background. It has a hard time drawing hands correctly, and often fails in drawing reflections. It also seems to have a hard time creating flat illustrations, or illustrations with limited color palates.
- murphyslab 4y ago> You correctly classified 26 of 30 (86%) images! > You identified 11 of 14 (78%) AI-generated images. > You identified 15 of 16 (93%) human-made images. Focal planes were another tell.
- fastball 4y agoI got 25 correct, and the majority of that was just looking at hands and text to see if they were messed up.
- lvoudour 4y agoText is a very good indication the photo is non-AI. Lots of AI generated images struggle with it, I don't know why.
- zoklet-enjoyer 4y agoResults You correctly classified 22 of 30 (73%) images! You identified 15 of 18 (83%) AI-generated images. You identified 7 of 12 (58%) human-made images.
- brap 4y agoI found it pretty easy once I started looking at context. For example, “would this person be wearing these kind of earrings?”, etc. Seems like AI does faces incredibly well, but misses the broader picture.
- sdflhasjd 4y ago29/30. I've spent far too much time playing with StableDiffusion though, and those anime-style illustrations seemed too easy to pick out. I think the quiz could have been better with some more variety with the AI imagery.
- Dwedit 4y agoGot 24/30 (80%) Look at the hands, look for obvious repeating patterns in foliage, look for lines that don't connect right.
- mbrock 4y agoalso look for geometric details that a human artist wouldn't bother with because they don't really make sense like some golden swirly jewelry thing on a dress that barely looks like anything
- ilkke 4y ago29/30, were not there yet :) Thanks, this was a fun and revealing experience
- musk_micropenis 4y agoYou're not even going to tell me which ones I got right?
- sha-3 4y agoI only got one wrong and I want to know which one I missed.
- rockzom 4y agoResults You correctly classified 26 of 30 (86%) images! You identified 10 of 12 (83%) AI-generated images. You identified 16 of 18 (88%) human-made images.
- woolion 4y ago>You correctly classified 28 of 30 (93%) images! >You identified 16 of 17 (94%) AI-generated images. >You identified 12 of 13 (92%) human-made images. I'm pretty sure the errors are the only two times I hesitated a fraction before clicking, it would be nice to have them in the summary. Most AI images have issues that I find pretty jarring after having seen a lot. It's a bit like seeing somebody without drafting fundamentals but perfect rendering skills. Currently the only way to really have human level output is to regurgitate something very close to the training data. So I don't think way to make it really hard and "fair" at the same time.
- anonymousDan 4y agoHow about you pay us for training your models instead of doing it for free!
- ronsor 4y agoThese results are not used (at least by me) to train models.
- timeon 4y ago24 of 30 (80%) My key for AI was: Does it looks like kitch? So probably there were few false positives.
- raverbashing 4y ago> You correctly classified 13 of 30 (43%) images! Huh tricky. Some might be easier than others
- niclot 4y agoThis would have been so easy if the images were generated by Dalle. It always has huge ugly artifacts
- zer0tonin 4y ago>You correctly classified 22 of 30 (73%) images! >You identified 12 of 12 (100%) AI-generated images. >You identified 10 of 18 (55%) human-made images. I draw regularly so that may have helped. I managed to identify the AI images because they contained very AI-like mistakes (ie. poorly defined hands, inexact facial symmetry and shadows mismatching the object). When the image contained no obvious mistakes, it was more or less a coin flip for me, turns out the images without mistakes were probably all from humans.
- kemyd 4y agoYes, the person will have more than five fingers
- hackerman123469 4y agoHere are my results: Personally I have been generating a lot of images using AI, so I know a lot of the artifacts to look out for with AI generated images. Results ---- You correctly classified 22 of 30 (73%) images! You identified 12 of 13 (92%) AI-generated images. You identified 10 of 17 (58%) human-made images.
- cal85 4y agoTo go through all that and not be shown the answers at the end is beyond infuriating.
- ronsor 4y agoIf you save your email, full results will be emailed next week.
- gus_massa 4y agoI tried this morning (19 of 30 (63%)). I just tired again, and clicked "Continue Quiz!" and then "Save for later... [arrow]" and it offered the possibility to add my email. So the GP can still fill an email and get the result next week. (With the real email or mailinator.) Perhaps you should change the text form "Save for later... [arrow]" to something like "Get the results by email... [arrow]".
- davikr 4y ago> You correctly classified 26 of 30 (86%) images! > You identified 14 of 18 (77%) AI-generated images. > You identified 12 of 12 (100%) human-made images.
- lotto-win 4y ago76% whats your score?
- rich_sasha 4y ago19/30 Interestingly, I'm not experienced with AI art, but I am a photographer and used to do 3D graphics. I focused on composition, interest and "overhype" - yes you could add a glow / halo effect here, but does it look right? Would this photo be interesting to a photographer, or is it a bit meh? So while my hit rate is lower than others mentioned on this thread (and not inconsistent with 50:50 guess really, so p-value of 12%), it feels like there are some non-detail aspects that aren't human. But even then, distinguishibility doesn't mean it's bad. For the most part, these were all very "accomplished" pictures - if you could make them as a human, you would be pretty pleased with yourself.
- anotheryou 4y agoaww, you don't get to see your mistakes? I got 80% right. Always interesting what where the clue can be found (fancy mirroring, subtle but correct things, small text, textures, eyes, hands...)
- smusamashah 4y agoBeing on /r/StableDiffusion teaches you so many things AI is bad at. You correctly classified 29 of 30 (96%) images! You identified 15 of 15 (100%) AI-generated images. You identified 14 of 15 (93%) human-made images. I looked for - missing symmetry in faces, symmetry in clothes/costumes - lines ending up nowhere. AI diffuses lines into something else often - bad hands, bad eyes - nonsensible scale e.g. a mountain shouldn't look that big or that small - missing consistency. AI tends to loose consistency easily. - badly written text, AI can not do text properly. if you can make sense of text its not by AI
- phowat 4y agoI'm not on /r/StableDiffusion and just by reading your comment beforehand, I managed to get 23 of 30. Not bad.
- shantara 4y agoThat's a great summary. Another telltale sign is the discontinuity in the partially obstructed background. If you have a human subject in the foreground, the parts of the background to the left and to the right of the subject do not connect properly. What should be single continuous parts of a building, a window, a railing or a landscape are drawn on different heights or otherwise do not form a whole structure.
- smusamashah 4y agoBy consistency I was meaning to say wrong continuity as you put it. BTW for some anime images I felt like i have seen them on that subreddit. Even if not those exact images, I have seen similar. That particular style (coloring, smoothness etc) also made me look carefully for flaws.
- shantara 4y agoThose particular images were so generic with the characters lacking any distinct traits, they could have easily been from either Stable Diffusion, or some ultra-low budget visual novel.
- glandium 4y agoWhen it's artwork, how good can we assume the humans to be? Because some look very much like they could have been done by AI, or a mediocre human...
- amelius 4y agoThe AI-generated ones are also human-made; the difference is that an AI messed with them.
- jokowueu 4y agoYou correctly classified 25 of 30 (83%) images! You identified 12 of 12 (100%) AI-generated images. You identified 13 of 18 (72%) human-made images.
- boredemployee 4y agoI wonder if all the text people input here, about the models' mistake, could help the model somehow.
- overlisted 4y agoThe city drawings have very obvious underdiffusion in them.
- tumidpandora 4y agoResults You correctly classified 24 of 30 (80%) images! You identified 14 of 18 (77%) AI-generated images. You identified 10 of 12 (83%) human-made images.
- roryisok 4y agoI got stuck at #16 because it wouldnt let me progress past that point
- owenpalmer 4y ago>You correctly classified 25 of 30 (83%) images! not bad imo
- kazinator 4y agoVery tough calls on art, or scenes without a lot of shadow and light and geometric objects, like certain nature scenes. I tended to err toward AI. You correctly classified 22 of 30 (73%) images! You identified 13 of 14 (92%) AI-generated images. You identified 9 of 16 (56%) human-made images. I would be more reliable between "photo versus AI", for certain kinds of photos where you can look for certain features being wrong.
