# Transformer

The scanner uses the [transformers](https://github.com/huggingface/transformers) library and a Hugging Face model built to detect prompt injection phrases. If the score returned by the model is above a defined threshold, Vigil will flag the analyzed prompt as a potential risk.

* **Model:** [JasperLS/gelectra-base-injection](https://huggingface.co/JasperLS/gelectra-base-injection)

{% hint style="warning" %}
This model is prone to false positives. If this is the only detection that fires, you should manually review the results before taking any action on the submitted prompt.
