Usage

Run the generation script:

python ~/.claude/skills/nano-banana-pro/generate_image.py "your prompt here" [options]

Options

Option	Description	Default
`--resolution`	Output size: 1K, 2K, or 4K	2K
`--aspect`	Aspect ratio: 16:9, 1:1, 4:3, 9:16, 3:4	16:9
`--output`	Output directory path	./generated_images
`--reference`	Reference image(s) for style/editing (up to 14)	None
`--format`	Output format: png, jpeg, webp	png
`--no-text`	Add instruction to exclude text/typography	off
`--cinematic`	Add cinematic film style (ARRI, shallow DoF, grain)	off
`--photorealistic`	Add photorealistic style hints	off

Examples

Basic generation

python ~/.claude/skills/nano-banana-pro/generate_image.py "a serene mountain landscape at sunset, photorealistic"

Square image for social media

python ~/.claude/skills/nano-banana-pro/generate_image.py "abstract geometric pattern in blue and gold" --aspect 1:1 --resolution 2K

High-res with custom output

python ~/.claude/skills/nano-banana-pro/generate_image.py "futuristic city skyline" --resolution 4K --output ~/Pictures/ai-generated

Style transfer with reference image

python ~/.claude/skills/nano-banana-pro/generate_image.py "transform this into a watercolor painting" --reference input.jpg

Image editing with reference

python ~/.claude/skills/nano-banana-pro/generate_image.py "add a rainbow in the sky" --reference landscape.png

Output

Images are saved with timestamp filenames:

Format: {timestamp}_{sanitized_prompt}.{format}
Example: 20260106_143052_serene_mountain_landscape.png

The script outputs the full path to the generated image.

Requirements

Python 3.10+
google-genai library
GEMINI_API_KEY environment variable

Notes

Gemini 3 Pro Image requires paid billing (no free tier)
Generated images include SynthID watermarking
Reference images enable style transfer and editing capabilities
Raw prompts by default: Prompts are sent unadulterated. Use --no-text, --cinematic, or --photorealistic flags to add style hints.
