In case 5: Photos of Yourself in Different Eras

The output just looks like a clearly different person. Its difficult to production-ize things that are inconsistent.

After looking at Cases 4, 9, 23, 33, and 61, I think it might be suited to take in several wide-angle pictures or photospheres or such from inside a residence, and output a corresponding floor plan schematic.

If anyone has examples, guides, or anything to save me from pouring unnecessary funds into those API credits just to figure out how to feed it for this kind of task, I'd really appreciate sharing.

I can't provide a definitive answer for this - but I will say that the Google's SDK docs state that a single edit request is limited to a maximum of THREE images so depending on how many you have - you might have to sort of use the "Kontext Kludge", aka stitching together many of input images into a single JPEG.

Thanks a lot! I hadn't realized before that the `-image-preview` variant of Gemini-2.5-flash had such an annoying limitation.

I can report it to not really work well, or to require prompting beyond my skills.

If someone has an example that works, I'd love to see.

I wish open source models would go this route of quality. Instead, every single release since and including flux dev have had some of the worst AI look I've seen so far. Sure these models might produce less mangled bodies, but in terms of actual aesthetics they lack behind even SD1.5 while needing >10x the amount of parameters.

So it seems like image generation/deepfake proliferation is pretty inevitable. I imagine we can't trust any image anymore (for e.g. identification verification purposes) unless it is done in person or otherwise notarized somehow. Is there a way (NFT-ish?) to "tag"/sign an image to say it was taken by an actual camera?

jstanley 9/12/2025||

But how do you check that it was actually taken by a camera and not just tagged as such?

Secondly, even if you solve that, how do you know it's not a photograph of an AI-generated scene?

I think this is very obviously not the right approach.

I theory you could install some kind of TPM-like device to every hardware that signs the data with key generated by manufacturer. Should be designed in such a way that it is very easy to break it when trying to tamper with it

I guess both the camera and the image need keys. (But really I have no idea this stuff is out of my realm!)

I tried pushing this 5 years ago when at Apple but got nowhere. IMHO only the OEM’s can achieve this.

In the AI image generation scene, is there anything solid yet in the way of generating vector illustrations for apps?

smusamashah 9/12/2025||

It can print code output as image as well. I don't think it will work for complex logic though. https://x.com/smusamashah/status/1961081534661685392

I am not very good with graphics. Yesterday, I used nano Banana to create an image for the front cover of a report. It took about 5 minutes. Normally, I would have spent at least an hour and still would not have gotten as good an image.

The Gemini models save me about an hour a day.

qgin 9/12/2025||

Does the Nano Banana naming imply the existence of Regular Banana or even Mega Banana?

tasseff 9/12/2025|

It implies the existence of an inverse gigabanana.

Cute. I love the “Not backed by [Y]” badge in one of the source images, sweet irony of being on HN’s front page.

Has anybody ever connected a 3D printer to such a machine’s output? Some of the action figures should definitely be 3D-printed.

Remdo 9/12/2025|

I didn't try it but I've seen really good results, is some innovation going on under the hood that we don't know? Is the technology the same of similar models? I can't find technical info on the internet
