# LibreYOLO Web — Model Zoo
Pre-exported ONNX models for [libreyolo-web](https://github.com/xuban-ceccon/libreyolo-web), the browser-based multi-family YOLO detection library.
## Usage
```bash
npm install libreyolo-web onnxruntime-web
```
```typescript
import { loadModel } from 'libreyolo-web';
// Auto-downloads from this repo, zero config
const model = await loadModel('yolox-nano');
const result = await model.predict(imageElement);
```
