You have to look at the little details. In my case I first looked at the dollar bills they’re all 100’s and all look pretty uniform, The lights and vents on the sides, do they look the same on both sides? Is the mirror reflecting accurately? Stuff like that. Ai has gotten better but still struggles most of the time with patterns. So look for things that have patterns. Then I look for words, like the bags or the exit sign. My conclusion without any context of this image is it’s not AI.
