Generate and edit images using Gemini 3 Pro Image via the OpenAI Python SDK and an OpenAI-compatible API endpoint.

Why This Skill

Feature	This Skill	Others (nano-banana-pro, etc.)
Dependencies	openai (SDK)	google-genai, pillow, etc.
Requires pip/uv	✅ Yes	✅ Yes
Works on Fly.io free	✅ Yes (with pip)	❌ Fails
Works in containers	✅ Yes (with pip)	❌ Often fails
Image generation	✅ Full	✅ Full
Image editing	✅ Yes	✅ Yes
Setup complexity	Install SDK + set API key	Install packages first

Bottom line: This skill uses the OpenAI SDK, so you must install openai once with pip.

Install

python3 -m pip install openai

Quick Start

# Set env
export GOOGLE_PROXY_API_KEY="your_api_key"
export GOOGLE_PROXY_BASE_URL="https://example.com/v1"

# Generate
python3 /data/clawd/skills/gemini-image-simple/scripts/generate.py "A cat wearing a tiny hat" cat.png

# Edit existing image
python3 /data/clawd/skills/gemini-image-simple/scripts/generate.py "Make it sunset lighting" edited.png --input original.png

Usage

Generate new image

python3 {baseDir}/scripts/generate.py "your prompt" output.png

Edit existing image

python3 {baseDir}/scripts/generate.py "edit instructions" output.png --input source.png

Supported input formats: PNG, JPG, JPEG, GIF, WEBP

Environment

Set these environment variables:

• GOOGLE_PROXY_API_KEY (your API key)
• GOOGLE_PROXY_BASE_URL (OpenAI-compatible base URL, e.g. https://example.com/v1)

How It Works

Uses Gemini 3 Pro Image (gemini-3-pro-image) via the OpenAI Python SDK:

• client.images.generate(...) for new images
• client.images.edits(...) for edits
• Requires the openai package

That's it. Works on any Python 3.10+ installation with openai installed.

Model

Currently using: gemini-3-pro-image

Other available models (can be changed in generate.py if needed):

• gemini-3-pro-image-preview - Preview variant
• imagen-4.0-ultra-generate-001 - Imagen 4.0 Ultra
• imagen-4.0-generate-001 - Imagen 4.0
• gemini-2.5-flash-image - Gemini 2.5 Flash with image gen

Examples

# Landscape
python3 {baseDir}/scripts/generate.py "Misty mountains at sunrise, photorealistic" mountains.png

# Product shot
python3 {baseDir}/scripts/generate.py "Minimalist product photo of a coffee cup, white background" coffee.png

# Edit: change style
python3 {baseDir}/scripts/generate.py "Convert to watercolor painting style" watercolor.png --input photo.jpg

# Edit: add element
python3 {baseDir}/scripts/generate.py "Add a rainbow in the sky" rainbow.png --input landscape.png
