Nano Banana Basic Concepts
What is Nano Banana?
Nano Banana is Google's high-fidelity image generation model built on the Gemini API. It can generate realistic and high-quality images from text prompts, providing users with powerful AI image creation capabilities.
Core Features
1. Text-to-Image
Generate high-quality images from simple or complex text descriptions. This is the most fundamental and important feature of Nano Banana. Example Prompt:
Create a picture of a nano banana dish in a fancy restaurant with a Gemini theme
2. Image Editing (Image + Text-to-Image)
Provide existing images and use text prompts to add, remove, or modify elements, change styles, or adjust color grading.
3. Multi-Image Composition and Style Transfer
Use multiple input images to compose new scenes, or transfer the style from one image to another.
4. Iterative Refinement
Gradually optimize images through conversation, making fine adjustments until achieving the desired effect.
5. High-Fidelity Text Rendering
Accurately generate images containing clear, readable, and well-positioned text, perfect for logos, charts, and posters.
