How to Use Google Gemini's New Image Model Nano Banana?

Recently, the so-called “Banana AI” has been going viral across the internet—and now it’s officially live. Its real name is gemini-2.5-flash-image-preview, a powerful new image-processing tool from Google. Backed by the Gemini World Library, Nano Banana offers an incredibly strong user experience that feels almost unreal. In this guide, I’ll walk you through what Nano Banana is, its key advantages, how to use it, and some important tips to keep in mind.

I. What Exactly Is Nano Banana?

Google’s Gemini has long been a leader among AI products. Even back in the 2.0 version, its image processing capabilities were already impressive. Before Google even officially announced it, the stunning “AI figurine” images generated by Banana AI had already gone viral. When Google confirmed it, they highlighted three major strengths: state-of-the-art image generation and editing, incredible character consistency, and lightning-fast speed. Let’s take a closer look:

1. Native Multimodality

gemini-2.5-flash-image-preview isn’t a standalone product—it’s one of many models under the Gemini umbrella. It combines multiple functions, meaning even simple text prompts can result in complex image editing. Best of all, image generation costs as little as $0.039 per picture. Some users have joked that it doesn’t just outperform other AI models, it even rivals Photoshop.

2. Character Consistency

This is where Nano Banana really shines. Whether you’re generating people or products, the model keeps them consistent even across different scenes. For product photography and creative projects, this is a game-changer.

3. Multi-Image Fusion

Nano Banana can take up to three images, understand their elements, and fuse them into a single new creation. This gives creators far more flexibility when it comes to designing unique and imaginative visuals.

II. How to Use Nano Banana

To try out gemini-2.5-flash-image-preview, it’s important to go through the right channel. Simply searching for “Nano Banana” won’t work. The correct way is to open Google AI Studio and select the corresponding model.

If you want to generate the popular AI figurines, you’ll need to:

• Click the “+” button to upload an image

• Enter your Prompt in the text field (you can either use pre-made prompts found online or write your own)

The workflow is fairly simple, so even beginners can get started without much trouble.

III. Key Things to Keep in Mind

While gemini-2.5-flash-image-preview is powerful, there are a few important details you should pay attention to:

1. Stable Network Environment

AI image generation requires a reliable internet connection. High latency or unstable connectivity can lead to failed generations. Low-quality networks might even risk your account being flagged. I recommend using a high-quality Proxy for stability. Personally, I rely on IPFoxy residential proxies to keep my connection steady when accessing Google services.

2. Data Privacy & Compliance

Since Nano Banana supports image uploading and analysis, avoid uploading sensitive, private, or copyrighted images. Otherwise, you may face privacy leaks or copyright disputes.

3. Content Compliance

Although Nano Banana is powerful, don’t use it to generate violent, illegal, or infringing content. At best, Google will reject the request. At worst, your account may be restricted or suspended.

4. Device & Performance Requirements

Nano Banana is designed as a lightweight model, but it still requires some hardware support. For example, newer Android versions or GPU-enabled devices. Older devices may struggle to deliver a smooth experience.

5. Content Accuracy

Always remember: AI-generated content should be double-checked. Don’t rely solely on Nano Banana for commercial use—do a manual review to ensure compliance, accuracy, and quality.

IV. Final Thoughts

gemini-2.5-flash-image-preview (Nano Banana) brings fresh and exciting features to the table. But as with any new tool, learning the proper usage is the key to improving efficiency. Hopefully, this guide helps you better understand how Nano Banana works and how you can make the most of it!
