Ask HN: Any reliable AI-detectors for images?

I know "A.I." text detectors are not accurate, and while "A.I." image detection probably isn't foolproof either, I'm wondering if maybe there is any website that is more accurate than just flipping a coin.

I have four pictures of a single person, two of which I believe are modified by "A.I."

I found six different online detectors that I could upload the images to for the websites to test. Three of the websites matched my suspicions, and the other three did not.

One of the images looks obvious to me (shoulder doesn't match up with arm when hair seperates the two). The other picture shows rough skin on the person's arm and forehead, but their chest looks very smooth.

One of the websites which I think is accurate with this small sample, even lists what model is suspected to be used (Mid journey and Stable Diffusion) in my case.
