How to use

Step 1: Approach

Access the LMArena site (lmarena.ai)
https://lmarena.ai/ ?
Use the "Generate Image" or "Image Edit Arena" function

Repeat until Nano-Banana is randomly assigned

Step 2: Upload your image

Upload the original image you want to edit
When creating a new one, enter only the text prompt

Step 3: Enter the command

Use English prompts (higher chance of selection)
Write specific and clear commands
Example:
"Change the bottom character to 2B from Nier: Automata"
"Replace background with sunny studio, keep natural product reflections"
"Add soft key light to brighten the face"
“Adjust white balance to cool tone”

Step 4: Step-by-step fine-tuning

Utilize the multi-turn conversation feature
Don't request all edits at once, proceed in stages
After checking the results at each step, request additional modifications.

Step-by-step approach - complex edits are broken down into several steps.
English usage - better results with English prompts than Korean prompts
