Nano Banana is the engine powering Google’s newest AI image tools, including Gemini 2.5 Flash (for speed) and Gemini 3 Pro (for detail). It stands out because it “thinks” about real-world physics before drawing, allowing you to generate images with perfect lighting and texture.

This page is your complete Nano Banana Prompt Cheat Sheet. I have tested hundreds of commands to find the ones that actually work for everything from real-looking photos to anime characters.

Just tell it what you want and honestly, it will create it, just check my own examples below.

  • Be Specific: Details matter. Mention lighting, camera angles, art style, and mood.
  • Reference Artists: Use “in the style of [Artist Name]” to get a specific look.
  • Iterate: Use the output as a new input and ask for changes. “Now make the lighting more dramatic.”
  • Combine Concepts: Nano Banana is great at mixing ideas. “A castle made of clouds” or “a robot made of vintage clock parts.”
