Nano Banana AI Guide: Step-by-Step Tutorial to Create 3D Figurines with Google Gemini

The internet has a new obsession: Google’s “Nano Banana” AI, the quirky nickname for Gemini 2.5 Flash Image. This AI tool allows users to turn simple photos into hyper-realistic 3D figurines within seconds — and the results are flooding Instagram, TikTok, and X.

If you’ve been wondering how to join the trend, here’s a complete step-by-step guide to creating your own Nano Banana figurines for free.

Is Nano Banana AI Free to Use?

Yes. Nano Banana AI is free on Google AI Studio, as well as through the Gemini app on Android and iOS. Free users have limited prompts, while paid subscribers get higher limits.

How to Upload Photos to Nano Banana

1. Open the Gemini app or go to Google AI Studio.
2. Select the Nano Banana model (banana icon on Gemini or “Try Nano Banana” button on AI Studio).
3. Click the ‘+’ icon → choose Upload Image.
4. Select a photo (supported formats: JPEG, PNG, WEBP).

How to Create a 3D Figurine

Once your photo is uploaded, add a prompt to transform it into a figurine. Google India shared this ready-to-use prompt on X (Twitter):

“Create a 1/7 scale commercialized 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 content on the computer screen is a 3D modeling process of this figurine. Next to the computer screen is a toy packaging box, designed in a style reminiscent of high-quality collectible figures, printed with original artwork. The packaging features two-dimensional flat illustrations.”

Click Generate and wait a few seconds. For example, a racing car image we tested took just 18.9 seconds to turn into a 3D figurine.

Can You Customize the Results?

Yes. You can tweak the prompt — for example, change poses, accessories, or environments — to get unique results. Once generated, you can download and share your figurine on any platform.
