Every single image is being flagged as "potentially AI generated" for me, including images I know for a fact are real (i.e. the "Lenna" image).

Though, when I try on my phone, I'm not seeing anything tagged as AI.
Ideally should tune whatever method you're using to determine this. Obviously this is a bit tricky to make work properly, but there's no point having it if it's going to flag every single image.
