Nano Banana Pro OpenRouter

Overview

Generate or edit images with OpenRouter using the google/gemini-3-pro-image-preview model. Support prompt-only generation, single-image edits, and multi-image composition.

Prompt-only generation

uv run {baseDir}/scripts/generate_image.py \

  --prompt "A cinematic sunset over snow-capped mountains" \

  --filename sunset.png

Edit a single image

uv run {baseDir}/scripts/generate_image.py \

  --prompt "Replace the sky with a dramatic aurora" \

  --input-image input.jpg \

  --filename aurora.png

Compose multiple images

uv run {baseDir}/scripts/generate_image.py \

  --prompt "Combine the subjects into a single studio portrait" \

  --input-image face1.jpg \

  --input-image face2.jpg \

  --filename composite.png

Resolution

  • Use --resolution with 1K, 2K, or 4K.
  • Default is 1K if not specified.

System prompt customization

The skill reads an optional system prompt from assets/SYSTEM_TEMPLATE. This allows you to customize the image generation behavior without modifying code.

Behavior and constraints

  • Accept up to 3 input images via repeated --input-image.
  • --filename accepts relative paths (saves to current directory) or absolute paths.
  • If multiple images are returned, append -1, -2, etc. to the filename.
  • Print MEDIA: <path> for each saved image. Do not read images back into the response.

Troubleshooting

If the script exits non-zero, check stderr against these common blockers:

Symptom

Resolution

OPENROUTER_API_KEY is not set

Ask the user to set it. PowerShell: $env:OPENROUTER_API_KEY = "sk-or-..." / bash: export OPENROUTER_API_KEY="sk-or-..."

uv: command not found or not recognized

macOS/Linux: curl -LsSf https://astral.sh/uv/install.sh | sh. Windows: powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex". Then restart the terminal.
