A new leak suggests the upcoming Nano Banana 2 model could bring serious improvements to Google’s image generation tools. We’re talking native 2K images, 4K upscaling and a multi-stage process designed to reduce visual blemishes and boost more realistic images.
The leak surfaced on X and outlines what appears to be a major update to Google’s image generation pipeline — possibly nicknamed “Gempix.”
If the leak is accurate, this model might offer more polished, usable results. In fact, the output could be ideal for social content, marketing visuals and creative projects. Maybe I should have waited for the next-gen model before making my holiday cards with Nano Banana. While we wait for what’s next, here’s a look at what the leak says about the newest model:

🚨 Nano Banana 2 completely smashed both the clock AND full wine glass tests in ONE IMAGE. “11:15 on the clock and a wine glass filled to the top” Holy. Shit. https://t.co/SedbYL92PX pic.twitter.com/q47HW04ZsHNovember 8, 2025
Here’s what we know about Nano Banana 2 so far, particuarly, the ‘Lightbox’ feature:
You may like
- 2K native image resolution, with optional 4K upscaling
- Multi-stage generation: plan > verify > refine > generate
- Fewer hallucinated details like extra fingers, missing limbs and incorrect on-image text
- Improved lighting, structure, and line clarity
Unlike current tools that sometimes rush to generate images with bizarre anatomy or poor contrast, the Nano Banana 2 leak indicates the mode prioritizes quality over speed.
It may even “check” and refine its own outputs before serving them up. If so, this could be a big win for visual consistency, nuance and even better text within the image.
Why it matters
For anyone using AI-generated images in real-world projects such as mockups, client decks YouTube thumbnails, ads and more, quality is everything. One wrong detail can lead to going back to the drawing board and going through tokens to get that accurate image. However, the new model could eliminate extra steps if it delivers cleaner images with fewer edits.
And with competitors like OpenAI’s image generator baked into the chat, Grok, and even Meta constantly improving, this could keep Gemini among the best image generators available.
What we don’t know (yet)
It’s worth remembering: this is still a leak. Nothing is official, and Google hasn’t confirmed any of the features. Besides having no real confirmation about when Nano Banana 2 will actually be available, other key questions still remain:
- Will Nano Banana 2 be part of Gemini or Workspace tools?
- Will it be free or behind a paywall?
- Will it completely replace the current Nano Banana?
- How much will the extra steps slow down image generation?
- Will it roll out globally or stay limited to certain areas?
Bottom line
This Nano Banana leak fits with Google’s overall push toward higher-quality generative tools. Veo 3.1 (for AI video), Imagen 3 (for photorealism) and now Nano Banana 2 all suggest a shift toward precision and polish.
We don’t know if Gemini 3 or Nano Banana 2 will released first, or even possibly together. But you can count on Tom’s Guide to keep you informed as soon as Google confirms anything.
One thing is for sure now. If this leak is accurate, the next generation of AI images could look a whole lot better, making deepfakes even harder to spot.
