# enguard/medium-guard-128m-xx-prompt-safety-binary-guardset

This model is a fine-tuned Model2Vec classifier based on [minishlab/potion-multilingual-128M](https://huggingface.co/minishlab/potion-multilingual-128M) for the prompt-safety-binary found in the [AI-Secure/PolyGuard](https://huggingface.co/datasets/AI-Secure/PolyGuard) dataset.



## Installation

```bash
pip install model2vec[inference]
```

## Usage

```python
from model2vec.inference import StaticModelPipeline

model = StaticModelPipeline.from_pretrained(
  "enguard/medium-guard-128m-xx-prompt-safety-binary-guardset"
)


# Supports single texts. Format input as a single text:
text = "Example sentence"

model.predict([text])
model.predict_proba([text])

```

## Why should you use these models?

- Optimized for precision to reduce false positives.
- Extremely fast inference: up to x500 faster than SetFit.
