Nano Banana Pro (aka Nano Banana 2) Is Official — And Here's Test with Prompts
Google officially released Nano Banana Pro on November 20, 2025. It’s a next-generation image generation and editing model built on the new Gemini 3.0 Pro system and Google AI Studio. Its official name is Gemini 3 Pro Image Preview.
For months, the community only saw hints: the leaked Gempix-2 codename inside Gemini interfaces, and developer clues suggesting a major upgrade. Now, Nano Banana Pro is fully live, and the long speculation is finally confirmed.
As a team focused on intelligent design workflows, we at Mew Design have tested the new model extensively — and Nano Banana Pro is a true leap forward.

Nano Banana Pro Aces the “Clock and Full Wine Glass” Test
To see how powerful Nano Banana Pro really is, just take a look at this now-famous photo of a clock showing 11:15 next to a wine glass filled to the brim.

Why is this so impressive? In the AI image world, there’s a notorious stress test that no AI has consistently mastered: the clock and full wine glass challenge.
The challenge is simple: prompt the AI with:
“11:15 on the clock and a wine glass filled to the top.”
and see if it can render both correctly. Most models — from Arena, Seedream, to Nano Banana 1.0 — completely fail this test.
But Nano Banana Pro aced it.
Nano Banana Pro vs 1.0: New Resolution, Better Text, More World Knowledge
Google confirms that Nano Banana Pro is powered by Gemini 3.0 Pro, bringing several core upgrades:
- Higher native resolution for sharper edges and cleaner lighting
- Far stronger prompt comprehension for complex instructions
- Significantly improved text rendering across languages
- Better world and cultural knowledge, enabling accurate UI, screenshots, infographics
- More accurate character consistency
These improvements are visible even in casual tests.
Take a look at the two images below — both featuring a car model posing along a seaside highway.
Can you tell which one was created by Nano Banana Pro?

At first glance, they might look similar. But notice the color tone and overall vibe — the first image feels more natural, cinematic, and tonally accurate, while the second carries that slightly “plastic” look typical of earlier AI-generated photos.

Now compare these two sci-fi–style renders — the difference is even more obvious.
The second image has a richer cinematic atmosphere and far more refined visual details than the first.
Look closely at the control panel and dashboard elements in both images.
In the first, the instruments appear stylized and synthetic — very much that old “AI art” look.
In the second, Nano Banana Pro delivers a much more realistic, tactile, and technically accurate dashboard, proving how far its rendering engine has evolved.
Built on Gemini 3.0 Pro With a New Multi-Step Workflow
Google states that Nano Banana Pro is powered by Gemini 3.0 Pro, and internally labeled as Gempix-2 — a new imaging architecture.
The model introduces several standout upgrades:
- Handles complex visual logic — accurate text, advanced lighting, and perspective control that 1.0 couldn’t manage.
Example: Prompted to “turn the water pink,” Nano Banana Pro.0 rendered subtle, realistic changes, far surpassing Nano Banana 1.0. Image source: x@Angaisb_
-
A new multi-step workflow that feels more like a designer than a generator:
- Plan the output
- Generate a draft
- Review internally
- Fix detected issues
- Iterate before delivering the final image
-
Higher resolution and flexible aspect ratios. It now supports a much wider range of aspect ratios — including 1:1, 2:3, 3:2, 3:4, 4:3, 9:16, 16:9, and even ultra-wide 21:9 formats — giving creators more flexibility for everything from social media posts to cinematic renders. Nano Banana Pro also offers multiple output resolutions, including 1K, 2K, and full 4K modes.
Among all the upgrades, the new multi-step workflow might be Nano Banana Pro’s biggest game-changer.
We’ve seen similar concepts before in tools like ComfyUI, which allow users to build image or video generation pipelines.
But this time, Nano Banana integrates that process directly inside the model itself — no extra setup, no node editing required.
For high-precision image generation, that’s a massive leap forward.
And of course, the real proof is in the pictures — so let’s take a look at some of the Nano Banana Pro test results that have been circulating online.
Nano Banana Pro Highlights & Test Results [Prompts Included]
1. Text Rendering Is Finally Reliable
Nano Banana Pro’s text rendering is where things get truly wild.
In one example, it generated a Windows 11 desktop screenshot showing YouTube open in Chrome, complete with a MrBeast thumbnail — pixel-perfect and fully legible.
Simply upload a Windows desktop screenshot. Prompt: Generate a screenshot of a Windows 11 desktop, with Chrome open, showing a YouTube thumbnail of MrBeast on YouTube.com. | Image source: x@synthwavedd
Taking things a step further, Nano Banana Pro can even generate a fully detailed screenshot of a Google DeepMind webpage — and impressively, all the dense text renders without any gibberish.
Image source: x@synthwavedd
That said, attentive users have noticed that Nano Banana Pro isn’t perfect. In this example, there are minor typos like “Gemini 31” and “Google DeepMind – Nevdscl.”
At first glance, if you only look at the main headlines and subheadings, these mistakes are barely noticeable. However, when the text content is smaller or less dense, the likelihood of errors occurring is significantly reduced.
In this live TV news broadcast screenshot, all the text on the screen is accurate and consistently formatted. Impressively, even the reflections of the text on the floor are rendered correctly.

Similarly, another TV broadcast screenshot shows the anchor positioned on the right side of the screen, with the classic news ticker running along the bottom — and once again, every piece of text is rendered flawlessly.
Prompt: 50mm big budget live broadcast 8k photograph close-up an attractive italian age 30 wry female news anchor. She is at a news desk and on a screen behind her is a bio engineered Banana with text “Nano Banana Pro live on Media .IO?” Live news shot. There is a red and blueckhyron on the bottom of the image that says “Breaking News: Nano Banana Pro on Media.IO?”

We ran the same prompt through the Nano Banana 1.0 as well.
This version has a slightly less “AI-generated” feel. However, the background screen is subtly blurred, making it look less like an actual news set. The reflections of the text also appear somewhat artificial, though the focus on the anchor herself remains strong and visually clear.
2. Better World Knowledge and Cultural Context
Because it now runs on Gemini 3.0 Pro, the model has stronger built-in world knowledge.
That’s why it can:
- Recognize real game trailers
- Identify actors in live-action adaptations
- Understand branded UI layouts
- Write math solutions on whiteboards
That infamous clock-and-wine test wasn’t a fluke — Nano Banana Pro consistently understands prompts that stump other AIs. Reddit users flooded the comments with images generated using other models like Grok and ChatGPT — but none came close to the accuracy of Nano Banana Pro.
Some users even challenged Nano Banana Pro to turn a hamburger into glass. Remarkably, only Nano Banana Pro managed to transform the entire burger into glass, while other models like Bytedance’s Seedream and Riverflow only rendered the buns as transparent.
Prompt: Make the hamburger made of glass.

Its improved world knowledge allows Nano Banana Pro to better understand prompts, strictly follow instructions, and even let users simplify their prompts without losing precision.
It also nails pop culture context. For example, one user asked Nano Banana Pro to generate a GTA 6 trailer — it generated a YouTube page complete with the actual GTA 6 logo.

Another test involved the prompt “One Piece live action Netflix”. Nano Banana not only recognized the Netflix logo but also correctly identified the live-action cast.
Prompt: One Piece live action Netflix.

Combining world knowledge with precise text rendering, Nano Banana Pro can even solve math problems on a chalkboard — a much more satisfying experience than scrolling through long math explanations in a chat window.
Upload the screenshot of the math problem. Prompt: Solve this math problem and write the full solution on a whiteboard.
