This thing's ability to produce entire infographics from a short prompt is really impressive, especially since it can run extra Google searches first. I tried this prompt: Infographic explaining how the Datasette open source project works Here's the result: https://simonwillison.net/2025/Nov/20/nano-banana-pro/#creat...

Is the infographic accurate in terms of the way datasette wprks?

Almost entirely. I called out the one discrepancy in my post:

> “Data Ingestion (Read-Only)” is a bit off.

The interesting tidbit here is SynthID. While a good first step, it doesn't solve the problem of AI generated content NOT having any kind of watermark. So we can prove that something WITH the ID is AI generated but we can't prove that something without one ISN'T AI generated. Like it would be nice if all photo and video generated by the big players would have some kind of standardized identifier on them - but now you…

It would be more productive for camera manufacturers to embed a per-device digital signature. Those care to prove their image is genuine could publish both pre and post processed images for transparency.

I...worked on the detailed Nano Banana prompt engineering analysis for months ( https://news.ycombinator.com/item?id=45917875 )...and...Google just...Google released a new version. Nano Banana Pro should work with my gemimg package ( https://github.com/minimaxir/gemimg ) without pushing a new version by passing: g = GemImg(model="gemini-3-pro-image-preview") I'll add the new output resolutions and other features ASAP…

In case anyone missed Max's Nano Banana prompting guide, it's absolutely the definitive manual for prompting the original Nano Banana... and I tried some of the prompts in there against Nano Banana Pro and found it to be very applicable to the new model as well. https://minimaxir.com/2025/11/nano-banana-prompts/#hello-nan... My recreations of those pancake batter skulls using Nano Banana Pro: https://simonwillison.ne…

How do you know Simon? It's certainly a blog post, with content about prompting in it. If your goal is to make generative art that uses specific IP, I wouldn't use it.

Nano Banana has been the only model I’ve really loved. As a small businesses who makes products, it’s been a game changer on the marketing side. Now when I’ve got something new I need to advertise in a hurry, I take a crappy pic and fix it in that. Don’t have a perfect model ready yet? That’s ok, I can just alter to look exactly like it will.

What used to cost money and involve wait time is now free and instant.

Some days it feels like I'm the only hacker left who doesn't want government mandated watermarking in creative tools. Were politicians 20 years ago as overreative they'd have demanded Photoshop leave a trace on anything it edited. The amount of moral panic is off the charts. It's still a computer, and we still shouldn't trust everything we see. The fundamentals haven't changed.

Easy to say until it impacts you in a bad way:

https://www.nbcnews.com/tech/tech-news/ai-generated-evidence...

> “My wife and I have been together for over 30 years, and she has my voice everywhere,” Schlegel said. “She could easily clone my voice on free or inexpensive software to create a threatening message that sounds like it’s from me and walk into any courthouse around the country with that recording.”

> “The judge will sign that restraining order. They will sign every single time,” said Schlegel, referring to the hypothetical recording. “So you lose your cat, dog, guns, house, you lose everything.”

At the moment, the only alternative is courts simply never accept photo/video/audio as evidence. I know if I were a juror I wouldn't.

At the same time, yeah, watermarks won't work. Sure, Google can add a watermark/fingerprint that is impossible to remove, but there will be tools that won't put such watermarks/fingerprints.

If there was a standardized identifier, there would be software dedicated to just removing it. I don't see how it would defeat the cat and mouse game.

I don't think it will be easy to just remove it. It's built into the image and thus won't be the same every time. Plus, any service good at reverse-image search (like Google) can basically apply that to determine whether they generated it. There will always be a way to defeat anything, but I don't see why this won't work for like 90% of cases.

Definitely, but don't sleep on its generative capacities either. You can give it a image and instruct it "Use the attached image purely as a stylistic reference" and then proceed to use it as a regular generative model.

Indeed. Is Nano Banana now Google flagship image gen model (over Imagen 4)?

In my tests it does outscore Imagen3 and Imagen4 even in the generative capacity, but my benchmark is more focused around prompt adherence. I'd wager that for certain photorealistic tests Imagen4 is probably better.

What can nano-banana do that chatGPT made images can't? Or is it only better for image editing from what I can gather from these comments so far. I haven't used it so genuinely curious.

I believe it’s an internal code name that stuck.

To expand, it comes from the stealth name it was given on LMArena I believe. The model made news while still in "stealth mode" and so Google capitalised on the PR they'd already built around that and just launched it officially with the same name.

I see, naturally this is the first I've heard of it ;)

I tried the same prompt as one of the examples ( https://i.imgur.com/iQTPJzz.png ), in the two ways they say you can run it, via Google Gemini and Google AI Studio (I suppose they're different somehow?). The prompt was "Create an infographic that shows hot to make elaichi chai" and Google Gemini created a infographic ( https://i.imgur.com/aXlRzTR.png ), but it was all different from what the example showed. Google AI…

Whoever said there was a universal recipe for Elaichi Chai? It makes sense that there would be different recipes. If you are more stringent with the prompt and give it the proper context of what you want the steps to be, you'll arrive at that consistency.
