## Features

- **High-quality image generation** using the Chroma model
- **Customizable parameters**: width, height, steps, CFG scale, and seed
- **Pre-cached examples** for instant preview and testing
- **Professional UI** with Gradio interface

## Example Prompts

The app includes 11 pre-configured example prompts with optimized parameters:

1. **High-fashion portrait** with anaglyph 3D effect
2. **Young man** with captain's hat and sunglasses

3. **Customize**: Modify example prompts to create variations
4. **Generate**: Click the Generate button to create new images

## Parameters

- **Prompt**: Describe what you want to generate
- **Negative Prompt**: Describe what you want to avoid
- **Width/Height**: Image dimensions (512-2048px)
- **Steps**: Number of denoising steps (1-50)
- **CFG Scale**: How closely to follow the prompt (1-20)
- **Seed**: Random seed for reproducible results (-1 for random)

## Technical Details

- Built with **Gradio** for the web interface

- Supports **GPU acceleration** with Spaces
- **Automatic caching** for optimal performance

## Running Locally

```bash
