# FritzStack/IRF-QWEN8B_light-mlx-4Bit

The Model [FritzStack/IRF-QWEN8B_light-mlx-4Bit](https://huggingface.co/FritzStack/IRF-QWEN8B_light-mlx-4Bit) was converted to MLX format from [FritzStack/IRF-QWEN8B_light](https://huggingface.co/FritzStack/IRF-QWEN8B_light) using mlx-lm version **0.31.2**.

## Use with mlx


```bash
pip install mlx-lm
!pip install git+https://github.com/Fede-stack/TONYpy.git
```

```python
from TONY.IRF import IRFPredictor_mlx

text = 'Some days I keep living, even though I feel completely alone in the world'
irf = IRFPredictor_mlx(model_name='FritzStack/IRF-QWEN8B-mlx-DoubleQ4')
irf.highlight_evidence_IRF(text)
```
