Nano Banana Antigravity (Gemini 3 Pro Image via OAuth)

Generate images using Nano Banana Pro (Gemini 3 Pro Image) via your existing Google Antigravity OAuth credentials.

No separate API key needed! Uses the same OAuth tokens as your OpenClaw Antigravity provider.

Generate Image

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

Generate with Options

uv run {baseDir}/scripts/generate_image.py \
  --prompt "a sunset over mountains" \
  --filename "sunset.png" \
  --aspect-ratio 16:9 \
  --resolution 2K

Edit/Composite Images

uv run {baseDir}/scripts/generate_image.py \
  --prompt "add sunglasses to this person" \
  --filename "edited.png" \
  -i original.png

Multi-image Composition

uv run {baseDir}/scripts/generate_image.py \
  --prompt "combine these into one scene" \
  --filename "composite.png" \
  -i image1.png -i image2.png -i image3.png

Options

  • --prompt, -p (required): Image description or edit instructions
  • --filename, -f (required): Output filename
  • --input-image, -i: Input image(s) for editing (can be repeated)
  • --aspect-ratio, -a: 1:1 (default), 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9
  • --resolution, -r: 1K (default), 2K, 4K

Authentication

Uses existing OpenClaw Antigravity OAuth credentials. Make sure you're authenticated:

openclaw models auth login --provider google-antigravity

The script looks for credentials in:

  • ~/.openclaw/credentials/google-antigravity.json
  • ~/.config/openclaw/credentials/google-antigravity.json
  • ~/.config/opencode/antigravity-accounts.json

Notes

  • The script prints a MEDIA: line for OpenClaw to auto-attach on supported chat providers.
  • Do not read the image back; report the saved path only.
  • Uses timestamps in filenames for uniqueness: yyyy-mm-dd-hh-mm-ss-name.png
  • Falls back to regular Nano Banana if Nano Banana Pro isn't available yet.
