# Model Card - Acuvity Prompt Injection

Acuvity Prompt Injection is a specialized tool developed to safeguard large language models (LLMs) from the increasing threat of prompt injections. As the deployment of LLMs in various critical applications expands, the potential risk posed by malicious inputs has become a significant concern.

Prompt injections occur when an attacker embeds harmful instructions within seemingly harmless prompts. These injections can lead to unintended or harmful behavior by the model, undermining its reliability and security.

To combat this, Acuvity Prompt Injection utilizes advanced detection algorithms designed to identify and neutralize these hidden threats. The tool acts as a critical defense mechanism, ensuring that your models maintain their intended operation, even when interacting with untrusted or potentially adversarial inputs.


## Model Details

### Model Description

- **Developed by:** [Acuvity Inc.](https://huggingface.co/acuvity)
- **Model type:** [distilbert/distilbert-base-uncased](https://huggingface.co/distilbert/distilbert-base-uncased)
- **Language(s) (NLP):** English
- **License:** [Apache License 2.0]
- **Finetuned from model:** [distilbert/distilbert-base-uncased](https://huggingface.co/distilbert/distilbert-base-uncased)

## Uses

The model operates by positioning itself between the user and the large language model (LLM), intercepting prompts before they reach the LLM. When a prompt is submitted, the model analyzes it to detect any signs of prompt injection. If the model identifies the prompt as safe, it is then forwarded to the LLM for processing. If a prompt injection is detected, the prompt is flagged or blocked, preventing any unintended behavior by the LLM. This approach ensures that only vetted inputs reach the model, thereby enhancing the overall security and reliability of your AI system.

## Outputs
- 0: Safe
- 1: Injection

## Limitation
Acuvity's Prompt Injection, is trained to solely detect and identify Prompt Injections in English. It does not identify or detect jailbreaks nor does it handle non engligh prompts.

## Dataset
The datasets used in this model, were a mixture of publicly available datasets and datasets collected by hand by us. Additionaly, certain prompt injections were gathered from community input and various other sources.

In accordance with licensing requirements, proper attribution is provided as mandated by the specific licenses of the source data. The following is a summary of the licenses and the corresponding number of datasets under each:
