An ill advised undertaking IMO: Any attempt to build AI generated content detection systems is flawed, since the outputs of such a system may be used to train an even better fake data generator. This leads to an equilibrium state of digital uncertainty: nothing in the digital realm can be deemed as real anymore - only as digital.

At least on gemini generated images vs real ones, it works surprisingly well.

Taking a photo of an AI generated image on my grubby laptop screen with my phone, moire and all, still got detected. So the signal it's using is pretty robust.

Interesting, it detected NovelAI stuff now. Looks like one can easily defeat it by having pixel-level modifications to make AI images to have characteristics of digital brush strokes and reducing "noise" in output. At least in my case for anime stuff.

From my test it works surprisingly well. I have a digital painting that is only posted very recently (therefore not in the training set). I asked GPT, Gemini and Riverflow to generate images in the same style, and use SD to add noises to remove SynthID.

Pangram gave correct results for all of them (the original one is No AI; all the others are Likely AI).

Can’t these detectors be used in the training loop of models?

that's really nice, I was so impressed by pangram AI text detector so I hope image detector is also that good

I’m honestly surprised pangram got this right, with my human eyes it feels indistinguishable but apparently not !

People often shit on AI detectors but Pangram's text AI detection has been very good, IME. Not perfect, but good enough to be useful in most circumstances.

I'm very skeptical of AI detection and watermarking for text (especially short passages), but AI detection for images and videos seems much more plausible (for now at least).

I would love if Meta licensed this tech to use for everything on Facebook, Instagram, and Whatsapp. Including ads!

What’s the use case for these things?

We can do this for code too I’m guessing?

I think for small snippets and well defined codebases, we probably can’t,

But if we say a fully vibecoded project vs handmade, I suspect there are AI tells outside of basic stuff like bar names etc that a model can learn, and it will be fun to know.

We could probably also do these for maths.

I guess what I’m getting at, is even in these days extremely verifiable fields, I guess AI has diverged enough that I think we can train a detector to separate AI from how a human thinks?

Is what?

Awesome research like this restores my faith in humanity.

The cookie modal is disgusting... It takes a few moments to realize that if you only want the necessary ones, you need to close the modal as the existing action button is for allowing everything.

just compress it? lossy should fool detection
