What is Nano Banana?

Nano Banana is an image generation and editing tool based on Google’s Gemini Flash model, supporting high-resolution output, multi-style fusion, virtual dressing, and more, suitable for design, photography, content creation, and other scenarios. Due to its name containing the more familiar fruit “banana,” it is also referred to as the “banana model” by many users online.

Background

Recently, Google released the Gemini 3 model and upgraded the Nano Banana model, leading to various online applications that users can try. After the free user quota is exhausted, it will revert to the original Nano Banana model. Earlier, a prominent user generated some interesting business cards based on GPT-4o, which had a distinct geek style. I also tried various approaches but did not achieve the desired effect. Just as the Nano Banana upgrade occurred, I decided to give it a try, and the results were truly stunning. Below, I will outline the production process and prompt words; interested users can give it a shot.
