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…

This watermarking ceremony is useless. We will always have local models. Eventually the Chinese will release a Nano Banana equivalent as open source.

Qwen-Image-Edit is pretty good already: https://simonwillison.net/2025/Aug/19/qwen-image-edit/

Something I find weird about AI image generation models is that even though they no longer produce weird "artifacts" that give away that the fact that it was AI generated, you can still recognize that it's AI due to stylistic choices. Not all examples they gave were like this. The example they gave of the word "Typography" would have fooled me as human-made. The infographics stood out though. I would have immediately…

It's a bit odd to say, but another big clue identifying something as AI-generated is that it simply looks "too good" for what it is being used for. If I see a little info graphic demonstrating something relatively mundane, and it has nice 3D rendered characters or graphical elements, at this point it's basically guaranteed to be AI, because you just sort of intuitively know when something would've justified the human…

Funny enough that had crossed my mind with the woodchuck example, because at a glance I can't see any weird artifacts, but I felt confident I could tell it was AI generated immediately if I saw it in the wild, and I couldn't really explain why. My immediate guess was "well, who the hell would actually bother to make something like this?"

yeah sadly veo 3.1 has not caught up to the image generation capabilities. May be we need to work on how to make video generation more physically consistent. but the image generation results from banana pro are great.

another interesting use case with synth https://chat.vlm.run/c/1c726fab-04ef-47cc-923d-cb3b005d6262 . made a puppet from a image of a model and made the puppet dance.

The feet are doing unusual movements. Reminds me of leaf node cumulative error in overcompressed hierarchical animation.

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...

Did you check if the SynthID works when you edit the photos with filters like GrayScale?

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…

I just pushed gemimg 0.3.2 which adds image_size support for Nano Banana Pro, and I ran a few tests on some of the images in the blog. In my testing, Nano Banana Pro correctly handled most of the image generation errors noted in my blog post: https://x.com/minimaxir/status/1991580127587921971

- Fibonacci magnets: code is correctly indented and the syntax highlighting atleast tries giving variables, numbers, and keywords different colors.

- Make me a Studio Ghibli: actually does style transfer correctly, and does it better than ChatGPT ever did.

- Rendering a webpage from HTML: near-perfect recreation of the HTML, including text layout and element sizing.

That said, there may be regressions where even with prompt engineering, the generated images which are more photorealistic look too good and land back into the uncanny valley. I haven't decided if I'm going to write a follow up blog post yet.

The system prompt hacking trick doesn't work with Nano Banana Pro unfortunately.

That result for rendering HTML to an image (the Counter Info one) is pretty impressive.

Slightly off topic, but how are people creating long videos like 30 second videos that I often see on Instagram? It I try to use Veo to make split videos, it simply cannot maintain the style or weird quirks get into the subsequent videos. Is there anything else that's the best video generation model currently other than Veo?

>This is a GREAT example of the (not so) subtle mistakes AI will make in image generation, or code creation, or your future knee surgery. The mistake is in the prompting (not enough information). The AI did the best it could "What's the biggest known planet" "Jupiter" "NO I MEANT IN THE UNIVERSE!"

It doesn't affect your point but technically since the IAU are insane, exoplanets aren't technically planets and Jupiter is the largest planet in the universe.

Longer videos without cuts are usually made from the first/last frame feature available in Veo 3.1 and other video models like Kling 2.5

Can Google Gemini 3 check Google Flights for live ticket prices yet? (The Gemini 3 post has a million comments too many to ask this now)

https://gemini.google.com/share/19fed9993f06

Ah thanks, might have to make a throwaway account just for that.

Gemini 2 still goes "While I cannot check Google Flights directly, I can provide you with information based on current search results…" blah blah
