Guide to Gemini Nano Banana and Nano Banana Pro

In partnership with

One of the biggest stories we tracked in 2026 was the improvement in AI image models. And no model made a bigger splash than Google Gemini’s Nano Banana and Nano Banana Pro.

Here’s a guide to using Google’s image model, including what it is, where to find it and what you can do with Nano Banana.

What is Nano Banana?

Nano Banana is the codename for the image-generation and editing model officially known as Gemini 2.5 Flash Image, developed by Google DeepMind.

It was publicly released in August 2025 and integrated into the Gemini app, among other Google AI products. In November, Google released Nano Banana Pro. This version was built on Gemini 3 Pro (and known as Gemini 3 Pro Image), using Gemini’s state-of-the-art reasoning and real-world knowledge to visualize information even better than the first Nano Banana version.

How much could AI save your support team?

Peak season is here. Most retail and ecommerce teams face the same problem: volume spikes, but headcount doesn't.

Instead of hiring temporary staff or burning out your team, there’s a smarter move. Let AI handle the predictable stuff, like answering FAQs, routing tickets, and processing returns, so your people focus on what they do best: building loyalty.

Gladly’s ROI calculator shows exactly what this looks like for your business: how many tickets AI could resolve, how much that costs, and what that means for your bottom line. Real numbers. Your data.

Where do I find Nano Banana?

You can find Nano Banana integrated directly into the Gemini app (available on Android and iOS) and at gemini.google.com on the web. In the chat, look for the "Create images" option in the tools menu (often marked with a distinct banana icon 🍌) or simply ask Gemini to generate or edit an image to activate it.

Free Gemini users get a limited number of uses of Nano Banana Pro.

Beyond the main app, you can also access these capabilities through:

• Google Search: Using "AI Mode" to generate visuals.

• Google Workspace: Within tools like Slides (via the "Help me visualize" sidebar) and Google Vids.

• NotebookLM: To transform notes and sources into infographics or slide decks.

What can I do with Nano Banana?

Nano Banana and Nano Banana Pro are designed to be more than just standard image generators. They act as a "visual reasoning" engine that understands context, physics, and text.

Here is a breakdown of what you can do and where the model truly shines. Want more examples? Google shared some of the biggest Nano Banana trends of 2025.

What You Can Do

Prompt-to-Image: Create high-quality visuals from scratch, from photorealistic portraits to abstract digital art.

Intuitive Editing: Instead of using complex software, you can upload a photo and simply type: "Change my shirt to a blue hoodie" or "Remove the person in the background."

Multi-Image Blending: You can upload up to 14 different images and ask Nano Banana to combine them. For example, you can take a photo of your living room and a photo of a specific sofa and ask it to "Put this sofa into my living room."

Doodle-to-Edit: You can actually draw a rough circle on an image and say "Add a coffee mug here," giving you precise control over where new elements appear.

What It Does Exceptionally Well

High-Fidelity Text Rendering: Unlike older AI models that struggle with "gibberish" text, Nano Banana (especially the Pro version) can generate clear, readable text in various fonts and even multiple languages. This makes it perfect for posters, logos, and mockups.

Character Consistency: One of its strongest features is the ability to keep a person’s face or a specific character's look the same across different scenes. This is a game-changer for storyboarding, comics, or brand mascots.

Visual Reasoning & Fact-Checking: Because it is linked to Google Search, it can create contextually accurate infographics and diagrams. If you ask for an infographic on "How a solar panel works," it won't just draw random boxes; it will use actual facts to structure the visual.

Important guardrails and limitations

Google’s API docs note that generated images include an invisible SynthID watermark, as well as a physical watermark you can see in the bottom-right of images in this post.

Because realism is getting very strong, it’s smart to build in habits like labeling AI-made visuals and keeping originals for provenance.

Nano Banana examples

Prompt that shows clear text: A minimalist, vintage-style travel poster for the city of Tokyo. In the center is a stylized illustration of Mount Fuji. At the top, in bold, clean Art Deco typography, it says 'TOKYO'. At the bottom, in smaller elegant text, it says 'The City of Eternal Neon'

Prompt that shows visual reasoning and ability to understand 3D space: A hyper-realistic cross-section view of a high-tech underwater research base inside a massive glass sphere. You can see scientists working in a lab on the left, a sleeping quarters with a view of a coral reef on the right, and a submarine docking at the bottom. High-detail lighting with blue water reflections.

Prompt that shows consistent character: A 3D Pixar-style character of a small, fluffy purple monster with one large eye and a yellow baseball cap, standing in a sunny forest.

Now show that same purple monster with the same yellow cap, but he is now wearing a tuxedo and dancing on a stage under a spotlight.

Ready to go bananas?

Nano Banana is one of the quickest ways to turn a rough idea into a usable visual, because it can generate new images, make targeted edits with plain language, blend multiple images, and keep characters or subjects consistent across a set.

If you need more control for polished design work, Nano Banana Pro is built for tougher, multi-step editing and higher-quality output, including cleaner text rendering and more precise adjustments.
