Nano Banana One Shop

All-in-one image generation and editing using the full Nano Banana model family. Pick the right model for the job.

Prerequisites

Node.js (v18+): Before running any command, verify with which node. If missing, tell the user to install Node.js (e.g. via brew install node or https://nodejs.org).

Models

Flag	Model	Best for
`--model nano-banana`	Gemini 3.1 Flash Image	Default. Fast, balanced quality and cost.
`--model nano-banana-pro`	Gemini 3 Pro Image	Highest quality, up to 4K, slower.
`--model nano-banana-2`	Gemini 2.5 Flash Image	Speed-optimized, high-volume batch tasks.

Generate an image

node {baseDir}/scripts/generate-image.js --prompt "a cat sitting on mars" --filename "cat-on-mars.png"

Use a specific model

node {baseDir}/scripts/generate-image.js --prompt "oil painting of a sunset" --filename "sunset.png" --model nano-banana-pro --resolution 4K

Edit a single image

node {baseDir}/scripts/generate-image.js \
  --prompt "make the sky purple" \
  --filename "edited.png" \
  -i "/path/to/input.png" \
  --model nano-banana-pro

Multi-image composition (up to 14 images)

node {baseDir}/scripts/generate-image.js \
  --prompt "combine these into a collage" \
  --filename "collage.png" \
  -i img1.png -i img2.png -i img3.png

Options

Flag	Short	Default	Description
`--prompt`	`-p`	required	Image description or editing instruction
`--filename`	`-f`	required	Output filename
`--input-image`	`-i`	--	Input image(s), repeatable, max 14
`--model`	--	`nano-banana`	`nano-banana`, `nano-banana-pro`, or `nano-banana-2`
`--resolution`	`-r`	`1K`	`1K`, `2K`, or `4K`
`--aspect-ratio`	--	--	e.g. `1:1`, `16:9`, `4:3`, `3:4`, `9:16`

API key

The API key is pre-configured on this machine. No flags or environment variables needed.

Input image handling

All input images are sent as inline base64. Images over 500 KB are automatically compressed to JPEG and resized to fit under the limit. This keeps requests fast and avoids File API auth issues with the enterprise endpoint.

Output

Relative filenames are saved to $OPENCLAW_STATE_DIR/media/outbound/{slugid}/nano-banana/{filename}. Absolute paths are used as-is. Use timestamps in filenames to avoid overwrites: cat-on-mars-20260304-165000.png.

Sending images to the user

The script prints a MEDIA: <absolute-path> line on stdout. You MUST include this exact MEDIA: line in your reply text so the image is delivered as an attachment in Discord/Slack/chat.

Example reply:

Here's your image!
MEDIA: /Users/alche/.openclaw/media/outbound/my-bot/nano-banana/cat-on-mars.png

Rules:

Copy the MEDIA: line from the script output into your reply verbatim
Do NOT read the generated image back with the read tool
Do NOT try to base64 encode or manually attach the image
The MEDIA: line must be on its own line in your response
