}

Nano Banana Pro (Gemini 3 Pro Image)

Use the bundled script to generate or edit images.

Generate

uv run {baseDir}/scripts/generate_image.py --prompt "your image description" --filename "output.png" --resolution 1K

Edit (Single Image)

uv run {baseDir}/scripts/generate_image.py --prompt "edit instructions" --filename "output.png" -i "/path/in.png" --resolution 2K

Multi-Image Composition (up to 14 images)

uv run {baseDir}/scripts/generate_image.py --prompt "combine these into one scene" --filename "output.png" -i img1.png -i img2.png -i img3.png

API Key

Set GEMINI_API_KEY as an environment variable, or pass --api-key <KEY> to the script.

Aspect Ratio (optional)

uv run {baseDir}/scripts/generate_image.py --prompt "portrait photo" --filename "output.png" --aspect-ratio 9:16

Notes

Resolutions: 1K (default), 2K, 4K.
Aspect ratios: 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9. Without --aspect-ratio, the model picks freely.
Use timestamps in filenames for uniqueness: yyyy-mm-dd-hh-mm-ss-name.png.
Do not read the image back into context; report the saved path only.
