I don't know I really like the definitive indicator that something is AI so I can completely ignore anything else that comes from them.
sgarman•18m ago
I think the issue is it was never definitive. This is a great way to show people that.
esafak•12m ago
I have not read anyone claim that SynthID had a false alarm issue, so if it returned positive I would believe it is synthetic.

If someone's doing something you don't like, you can't really count on them doing it the way you prefer.
Tiberium•26m ago
This is a bit misleading as for Gemini it only properly removes the visible watermark. To remove SynthID it has to regenerate the image at low noise with SDXL, which will likely destroy a lot of small details, plus won't work for higher res properly (NB2 and GPT Image 2 support up to 4K image outputs)
gpt5•17m ago
Nano Banana 2 only supports 1K resolution (1024x1024) natively. Anything above that is upscaling. So this matches SDXL. GPT Image 2 does support 4k natively (but experimentally).

Where did you get that info from? According to Google's own docs as well as my own image generation tests via the API, it supports up to 4K natively for gemini-3.1-flash-image-preview (aka NB2).

It just defaults to 1K. But I didn't see anything in the docs stating that it's just a simple upscale for larger resolutions.

> Use cases where the threat model fits: You are preserving art or historical record against false-positive "AI-generated" labels.

Sorry, how does using AI to generate images have anything to do with this? Image generators cannot insert watermarks into things they did not generate, and it seems highly unlikely that you will get a false-positive watermark on human-generated art, especially if, as the readme says, these watermarks have high enough fidelity to trace to a specific session id. Plus the modifications to the image needed to erase watermarks would necessarily change the thing being "preserved."

[edit]: the more I read the more I'm convinced, the claimed use cases in the README are bullshit and the real reason is to provide a tool that helps people bypass "AI-generated" labels on social media for AI slop.

Tiberium•23m ago
I mostly agree about the justification in the repo being wrong, but wanted to engage about this point:

> Image generators cannot insert watermarks into things they did not generate

It's actually very easy to take a real image, ask Gemini/ChatGPT to modify some tiny part of it (could be something as silly as lighting/shadow/etc), and often the resulting image will be detected by their watermarking tools. This way you can easily present any real image as AI-generated.

j2kun•19m ago
Ignoring that a watermark removal tool does not help with this threat model, the claim is still true: the original image can not be changed, and instead a copy is created.
rezonant•18m ago
So what? I can also open an image in Photoshop and make sure it saves out some Photoshop specific EXIF data and try to claim the image was doctored. What I can't do is go and put my deceptive altered file up in place of the original in all the places on the Internet it exists.
akersten•19m ago
There's an underappreciated comment in the other thread about SynthID and OpenAI [0] that captures what (IMO) the hacker ethos on this should be. We care about privacy, we should not accept tools that barcode our every digital move. (note that the counter of "well, they don't do that yet" is not particularly convincing)

Building a tool that tries (and probably fails) to remove the watermark (due to the arms race that large corporate machines will win) is tacitly accepting the barcode. The hacker ethos should be, first and foremost, to run open source models locally without relying on a corporation.
akersten•12m ago
> [fighting against the system] is tacitly accepting the barcode.

I don't really see it. I think it's important to win on both fronts.

Accepting blindly destroying the concept of thruth should not be the hacker ethos either.
63stack•3m ago
Nobody said that?
bonoboTP•2m ago
It's already possible to lie with text. Pixels are pixels. If we can't blindly believe pixels to show the truth, we will be simply back to the pre-photography era which managed to have a concept of truth regardless.
tptacek•2m ago
It either works reliably or it doesn't; if it doesn't, it's better that everybody be clear about that.

What’s wrong with showing off AI bro? Why the shame?
