How it does on Flux

In our tests on images it never trained on, our image model marked 88% to 100% of images from most Flux versions as AI. Flux 1.1 Pro is the hard one: it catches about 7 in 10.

Images made with Flux in tools like ComfyUI often keep their generation settings inside the file. When they're there, we show them.

Things to check yourself

Flux is good at text and hands, so look for other giveaways: backgrounds that melt into each other, repeated details and lighting that doesn't add up.

Does it work on screenshots of Flux images?

Yes, but less well: screenshots and re-saves lose detail and any settings the file carried. Use the original file if you can.
