I hadn't been exposed to the new GPT-Image-2.5 model before this, so didn't have any "tells" to go off of, and found it almost impossible to begin with, but it seems the brain is pretty good at adapting for visual stuff! After 2 rounds, I was able to build up a 16-image combo, answering most within a second or two.I think the "tell" I ended up…

Reality Check — Slop Sense Think you can spot AI? Can you tell a real photo from AI? 60 seconds to find out. 🤔 https:// slop-sense.labtoagi.com/games/ is-this-image-ai/ # game # realitycheck # ai # reality # aislop # slopsense # photo # onlinegames # 60s

There are occasionally more obvious tells as well, if you look closely. Some examples that I saw:- A boat cast a shadow, but the mooring rope didn't- A bench leg was out of perspective, and didn't touch the ground- In a pile of logs,the ends were sharpened in an unnatural way[0]- In several there seems to be an inconsistent contrast between…

Highest score is 16,800. Highest streak is 60 in a row.I just came to HN to see if I won!Also, I do research on how people perceive images and video. I’ve published a couple papers and did my dissertation on how folks understand moving images.If you’re the developers of this game I’d love to help you parse this data. B L T P H D at V T dot E D…

Good reality check for people who proudly boasted about "always" being able to spot AI images.

not doable in short time with high certainty which means that from now on an image is only worth a thousand words

The fonts it uses for signs and posters. They often don't match the scene. The posters on a corkboard next to school gymnasium don't look like they were made by students or teachers, most likely amateurs at graphic design, they look professionally made. As for signs, a rustic looking sign isn't going to use helvetica-like typeface, it looks…

I don't get the scoring system: I got 0 points, but I got a streak of 2 in a row. Bizarre.

Highest I got was 26 in a row. AI seems to love generating "close up" images of a subject. Its like every image has to have an obvious subject (that was in the prompt), and it struggles to make scenes without a clear subject and more chaotic vibe. I notice this a lot with these "AI movies", every single camera shot has an obvious subject that…

Every generation prompt has this suffixed: The scene should feel incidentally noticed during daily life, not arranged for an advertisement. Natural perspective and subtle everyday wear. No cinematic grading, stock-photo staging, deliberate blur, artificial grain, fake low resolution, extreme background blur, exaggerated HDR or oversharpening. No…

Neat app but it makes me sad. Also I'm very curious as to where the real photos come from and how we can verify that they are indeed real. The timer thing doesn't really add any value, just stress.
-
It's hard to put into words but the "texture" of GPT-Image-2.5 is just a bit off, like the difference between blue noise and white noise. It's like someone turned up the local contrast just a little too high.
-
The time limit did make it quite challenging. I got 1,000 points with a max streak of 8 in a row. On second playthrough I got 3,550 / 12. It seems the AI images all come from a particular area of latent space that's quite easy to recognize once you get dialled in.So it's more of a "can you detect the GPT Image 2.5 house style", which is an easier…

Impossible to do on a phone. Zooming in is misinterpreted as a choice. Fix the game.Also the time limit is stupid and pointless.
-
I realized this is only somewhat difficult because of the 10s timer. Most people probably don’t spend more than 10s looking at a picture on social media, excellent project.
-
My most effective strategy is to ask: is there any reason for a human to take this picture?One AI-generated image was a bedside night stand, with no clutter other than a set of keys on top of a receipt. It looked perfectly real, no glitches or weirdness... other than the idea of someone taking a picture of it.Not a perfect strategy, though; I…

> 60 seconds to find out.> 90s round, 10s per image> Play 60 secondsThis is confusing. What does "90s round" mean if it's a 60 second game? Is it about the 1990s?
