Nano Banana (Gemini 2.5 Flash Image) is currently the #1 ranked AI image model on LMArena for both generation and editing. After months of using it, here's the workflow I've built for consistent, high-quality results.
Why Nano Banana?
Three features set it apart:
- Character Consistency — Create the same character across multiple images with different poses and scenes
- Precise Editing — Select and modify specific elements without regenerating the entire image
- Image Blending — Combine multiple source images into one natural composition
My Workflow
Step 1: Start with Tested Prompts
Don't write prompts from scratch. I use nanoprompts.org — a free library with 400+ tested prompts organized by use case. Pick a template close to what you need, then customize.
Step 2: Layer Your Prompt
Every good prompt follows this structure:
- Subject: Who or what is in the image
- Environment: Where the scene takes place
- Style: Art style or visual reference
- Lighting: Direction, color, intensity
Step 3: Refine with Editing
This is Nano Banana's killer feature. Got a great image with one wrong element? Select it and describe the change. No full regeneration needed.
Step 4: Maintain Consistency
For series work, establish your character parameters early. The case studies at nanoprompts.org show exactly how to maintain consistency across a series of images.

Results
Since adopting this workflow, I've cut my image generation time by ~60%. The combination of good prompts and Nano Banana's editing capabilities makes iteration much faster.
