# Image Upscaler by Each AI

Upscale images with advanced controls for creativity, resemblance, sharpening, and optional face/hand enhancement. Supports multiple Stable Diffusion base models and schedulers.

## Quick Start

> Requires an each::labs API key. Get one at [eachlabs.ai](https://eachlabs.ai).

```bash
curl -X POST https://api.eachlabs.ai/v1/prediction \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "each-upscaler",
    "version": "0.0.1",
    "input": {
      "image": "https://example.com/low-res-photo.jpg",
      "scale_factor": 2,
      "creativity": 0.35,
      "resemblance": 0.6,
      "num_inference_steps": 18
    }
  }'
```
