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 with is that almost all of the AI images tend to center around a very obvious main "subject" (a flower, a bike, a wrench, etc) – presumably an inherent artefact of generating from a prompt – with everything else around the subject having a very strange depth to it. The depth, focus, and bokeh around the main subject just never look quite right. If you look at an image and find it has a very strong central subject with a little too much depth separation than expected, there's a good chance it's AI.
I recognise that this method of finding a consistent "tell" will probably not hold for future models, unfortunately. Everything else looks almost perfect at this point.
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.
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.
But then, some people specialize in taking photos that others would not because they have in mind stock photos, art or something else. They see the world differently.
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 problem.
Not bad. I’d appreciate a much longer time limit. Got really rushed at the end. But this was crazy hard on my phone, I was straight guessing most of the time. I think I could be a little better with more time on a desktop screen.
Another idea would be games that were all pictures of a single category- like 10 AI and 10 real pictures of basketballs, or food on plates, etc.
But I think that your experience is actually the useful one that proves a point. Most people consume content on their phone (e.g instagram) and would usually just scroll by photos. They wouldn’t deeply analyze them.
This is executed so well, from the choice of photos to the rushing. Kudos!
Fwiw, my scores so far have mostly been negative (using a phone without my glasses on), but that's.. the point I guess? I guess I'm not alone in overestimating my success rate in spotting ai content when tired or under pressure. The whole photo premise is a beastly challenge in itself, it's easy to create somewhat convincing stock photos using AI, but it's very dependent on context and personality whether you spot it immediately, I guess.

Also the time limit is stupid and pointless.
> 90s round, 10s per image
> Play 60 seconds
This is confusing. What does "90s round" mean if it's a 60 second game? Is it about the 1990s?

Not a perfect strategy, though; I thought this one was AI for just that reason: https://commons.wikimedia.org/wiki/File:Potted_plant_1_2018-...

I'd appreciate an untimed mode.

Did I create the image myself?
Yes: Not AI
No: AI
The fact that the suck machine works isn't something to be proud of.
As fake news becomes more and more real and with photo evidence, this matters more and more.
