## Quick Start

> Requires inference.sh CLI (`belt`). [Install instructions](https://raw.githubusercontent.com/inference-sh/skills/refs/heads/main/cli-install.md)

```bash
belt login

belt app run infsh/real-esrgan --input '{"image_url": "https://your-image.jpg"}'
```


## Available Upscalers

| Model | App ID | Best For |
|-------|--------|----------|
| Topaz Image Upscaler | `falai/topaz-image-upscaler` | Professional quality, any image |

## Examples

### Upscale Any Image

```bash
belt app run falai/topaz-image-upscaler --input '{"image_url": "https://low-res-image.jpg"}'
```

### Workflow: Generate and Upscale

```bash
# 1. Generate image with FLUX Klein (fast)
belt app run falai/flux-2-klein-lora --input '{"prompt": "landscape painting"}' > image.json

# 2. Upscale the result
belt app run falai/topaz-image-upscaler --input '{"image_url": "<url-from-step-1>"}'
```

## Use Cases
