Generate or edit images via Gemini 3 Pro Image (Nano Banana Pro).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Nano Banana Pro (Gemini 3 Pro Image)

Use the bundled script to generate or edit images.

Generate

```bash
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)

```bash
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

- `GEMINI_API_KEY` env var

Notes

- Resolutions: `1K` (default), `2K`, `4K`.
- Use timestamps in filenames: `yyyy-mm-dd-hh-mm-ss-name.png`.

How to install

The exact contents, by fingerprint

mdr add bitterbot-ai/bitterbot-desktop/nano-banana-pro@sha256:24bd20686fc2f402

The line at the top of this page pins the label git:20260328.33f9833, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
