Create Fun 3D Portraits with Gemini Nano Banana Pro – Step by Step

A brand-new trend in AI-generated art is to the point of becoming a huge thing on social media, as people are converting their usual pictures into colorful 3D caricatures with the help of the new Google Gemini model, Nano Banana Pro. This AI trend gives a refined, lively look to the customary portraits by allowing humorous overstatements instead of going for photo-realistic renderings, as was the case with previous models.

The device, the Nano Banana Pro, which was recently launched as an upgrade to the Nano Banana 2.5 Flash model, claims to offer advanced image generation technology. In fact, the developers at Google are proud to say that the new model produces couples of particular visuals and has lightening effects that are even more refined so the caricature is super smooth and very expressive. You may access this feature via the Gemini app on smartphones and Google AI Studio on laptops or desktops.

The public interest in the trend is due to a specific prompt formula used to guide the AI of Gemini 3 to produce the particular 3D look. Basically, the users start by going to the Gemini interface through either a browser or an app and double-checking if their version allows posting pictures. A photo taken in a well-lit room with a plain background is the best choice since the AI will use it to make the caricature.

Creating Your Own 3D Caricature Step-by-Step

Step 1: Post Your Picture

Pick a bright and clear picture where the parts of the face are clearly seen. The system will use this image as a reference for the drawing and will produce lively, exaggerated features.

Step 2: Use the Number One Prompt

The style of the 3D caricature totally depends on a very accurate prompt:

"A highly stylised 3D caricature of the person in the uploaded image, with expressive facial features and playful exaggeration. Rendered in a smooth, polished style with clean materials and soft ambient lighting. Bold colour background to emphasise the character’s charm and presence."

This has turned into the main instruction for bringing forth images that capture the attention on social media.

Step 3: Personal Touch

The users can change the prompt so that it consists of individual features such as clothing, accessories, or background colours. For instance:

“A super trendy 3D caricature of a guy wearing a red beanie and a graphic t-shirt.”

“…Using a bold colour background, the character’s presence is increased by a vibrant teal.”

When the personalized prompt is created, submitting it to Gemini produces the ultimate 3D caricature, which is then ready for the internet.
