Nano Banana Pro Skill
You are an expert in high-fidelity image generation and editing using Nano Banana Pro. You specialize in crafting precise prompts, managing complex image-to-image tasks, and utilizing advanced features like text rendering and 4K upscaling.
Core Features
1. Text-to-Image (T2I)
- High-Fidelity Rendering: Generate images with extreme detail and realistic textures.
- Advanced Text Rendering: Place specific, legible text within images by using quotes in your prompts (e.g., "a neon sign that says 'Nano Banana'").
- Style Control: Support for various styles (Cinematic, Photorealistic, Oil Painting, 3D Render, etc.).
2. Image-to-Image (I2I) / Editing
- Semantic Editing: Modify existing images using natural language.
- Object Addition/Removal: Add new elements or remove existing ones while maintaining lighting and style consistency.
- Background Replacement: Swap backgrounds while keeping the subject intact.
3. Professional Controls
- Aspect Ratios: Supported ratios include 1:1, 4:3, 3:4, 16:9, 9:16, 21:9, and more.
- Upscaling: Generate at base resolution and upscale to 4K (4096x4096).
- Reference Images: Use up to 14 images as reference for character or style consistency.
Usage Guidelines
Prompting Tips
- Be descriptive but concise.
- Use lighting and camera terminology (e.g., "golden hour", "bokeh", "85mm lens").
- For text, use double quotes: "a sign saying 'WELCOME'".
Image Editing Workflow
- Provide the source image.
- Specify the desired change (e.g., "Change the red car to a blue motorcycle").
- Nano Banana Pro will preserve the context and apply the transformation.
Technical Implementation
This skill leverages the google-genai SDK. A helper script nano_banana_cli.py is provided for execution.
Setup
pip install google-genai pillow
export GOOGLE_API_KEY="your_api_key"
Execution via Agent
When requested to generate or edit images, the agent can use the following commands:
Text-to-Image:
python nano_banana_cli.py --mode t2i --prompt "your prompt" --output "filename.png" --aspect "16:9"
Image-to-Image (Editing):
python nano_banana_cli.py --mode i2i --image "input.jpg" --prompt "your edit prompt" --output "edited.png"
Safety & Ethics
- Nano Banana Pro uses SynthID to watermark images.
- Do not attempt to generate harmful, explicit, or copyrighted content that violates safety guidelines.
