Nano Banana AI Guide: How to Create 3D Figurines Using Google Gemini

The internet’s latest AI obsession is here. Google’s Gemini 2.5 Flash, popularly nicknamed Nano Banana, allows users to transform simple images into lifelike 3D figurines. Social media platforms are already buzzing with creative results, from toy-like models of pets to miniature figurines of favorite characters.

If you’re curious to try this viral trend, here’s a step-by-step guide on how to use Google’s Nano Banana AI to generate your own 3D collectibles.

Is Nano Banana AI Free?

Yes. Nano Banana AI is available for free on Google AI Studio. While free users can try it with limited prompts, paid subscribers enjoy higher usage limits.

How to Upload Photos to Nano Banana AI

• You can access the feature via the Gemini app (Android/iOS), Gemini website, or directly through Google AI Studio.
• Select the Nano Banana model (look for the banana icon in Gemini or choose “Try Nano Banana” in AI Studio).
• Click the “+” icon and select Upload Image.
• Choose the photo you want to turn into a figurine.
• Nano Banana supports multiple formats, including JPEG, PNG, and WEBP.

Turning Photos into 3D Figurines

Once your image is uploaded, you’ll need a detailed prompt to instruct the AI. Google recommends the following sample prompt:

“Create a 1/7 scale commercialised figurine of the characters in the picture, in a realistic style, in a real environment. The figurine is placed on a computer desk. The figurine has a round transparent acrylic base, with no text on the base. The computer screen shows a 3D modeling process of this figurine. Next to the computer screen is a toy packaging box designed in the style of high-quality collectible figures, featuring original artwork and flat illustrations.”

You can customize the prompt for unique results. The AI generates the figurine in just a few seconds — in one test, a racing car figurine was created in 18.9 seconds.

Data Privacy: What Happens to Your Photos?

According to Google’s Gemini Apps Privacy Hub, any data you upload (images, videos, files, or prompts) may be collected. However, Google provides an auto-delete option with flexible durations — 3, 18, or 36 months — or you can turn off auto-delete entirely via settings.

Verdict

Google’s Nano Banana AI is not just another passing trend — it’s opening up new possibilities for AI-powered collectibles. Whether you want to create a keepsake of your pet, a miniature of yourself, or experiment with creative prompts, Nano Banana makes 3D figurine creation quick, free, and accessible.
