Nano Banana Pro prompts drive viral trend of 3D chibi diorama images
|
| The creator noted the goal was to produce "cute little diorama lamps," emphasising the need for an enclosed cube, soft lighting, and small imperfections like dust or scratches to make the digital scene feel tangible. |
A new artificial intelligence-generated art trend centred on “Nano Banana Pro” prompts has gained wide attention on social media ahead of the Christmas season, with users creating 3D, cube-shaped dioramas that resemble illuminated desk lamps or miniature display boxes.
The trend focuses on generating isometric 3D scenes enclosed in a cube, featuring chibi-style miniature figures placed inside highly detailed rooms. The images are designed to resemble physical collectible toys, enhanced by soft internal lighting and small imperfections such as dust or surface scratches.
Origins of the trend
The format gained momentum after an AI creator, known online as @Arminn_Ai, shared a structured prompt that simplified the creation of these diorama-style images. The prompt follows a clear structure defining the subject, action, and setting, along with detailed visual instructions.
Google later amplified the trend by sharing a ready-to-use version of the prompt on social media, allowing users to generate complex-looking 3D scenes with minimal effort.

Technology behind the images
The images are generated using Nano Banana Pro, an image generation model built on Google’s Gemini 3 Pro architecture. The model is designed to deliver high-fidelity visuals with fine control over lighting, perspective, and materials.
According to publicly available information, Nano Banana Pro supports high-resolution outputs of up to 4K and allows the use of multiple reference images to maintain visual consistency. It is accessible through the Gemini app and Google’s enterprise AI offerings.
Growing festive use
With the festive season approaching, users are increasingly sharing personalised diorama images as greetings, profile pictures, and social media posts. The trend reflects a wider shift towards personalised AI-generated visuals made accessible through simplified prompting.
Google has not announced any new product launch or policy update linked specifically to this trend. The viral images are based on existing capabilities of the Gemini image generation system.
