Nano Banana is a structured prompting methodology that produces consistent, high-quality AI-generated images. Unlike random prompt guessing, it uses a specific token ordering that maximizes the AI's attention to details that matter.
The name comes from its approach: "Nano" refers to the granular, precise details you specify (like exact lighting temperatures, texture descriptions, camera angles), while "Banana" describes the curved narrative arc that guides the AI from the central subject outward to the environment.
This method eliminates "token drift" where the AI ignores later parts of your prompt. Every token has purpose. Every word drives the final image.
