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.

# Nano Banana Pro (Gemini 3 Pro Image)
Generate high-quality images with Google's Gemini 3 Pro Image API.
## Overview
**Nano Banana Pro** is the marketing name for **Gemini 3 Pro Image** (`gemini-3-pro-image-preview`), Google's state-of-the-art image generation and editing model built on Gemini 3 Pro.
## Quick Start
### Get API Key
1. Go to [Google AI Studio](https://aistudio.google.com)
2. Click "Get API Key"
3. Store securely as environment variable
### Basic Image Generation (Python)
```python
from google import genai
from google.genai import types
client = genai.Client(api_key="YOUR_GEMINI_API_KEY")
response = client.models.generate_content(
model="gemini-3-pro-image-preview",
contents="A serene Japanese garden with cherry blossoms and a koi pond",
config=types.GenerateContentConfig(
response_modalities=['TEXT', 'IMAGE']
)
)
# Process response
for part in response.candidates[0].content.parts:
if hasattr(part, 'text'):
print(f"Description: {part.text}")
elif hasattr(part, 'inline_data'):
# Save image
image_data = part.inline_data.data # Base64 encoded
mime_type = part.inline_data.mime_type # image/png
…
The line at the top of this page pins the label git:20260107.0951120, 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.
