SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prompt injection and jailbreak attempts threaten the safety of LLM applications; Prompt Guard detects and blocks malicious prompts and third-party data.

Core Features & Use Cases

  • Lightweight 86M-parameter classifier that detects prompt injections and jailbreak attempts.
  • Multilingual support across 8 languages; fast inference (<2ms on GPU).
  • Deployable with HuggingFace or batch processing for RAG security.
  • Filters prompts and third-party data to reduce risk in chatbots, assistants, and enterprise apps.

Quick Start

Install the required packages and run the detector on a user message to obtain a jailbreak risk score.

Frequently Asked Questions about prompt-guard

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I detect prompt injection and jailbreak attempts in LLM applications?

To detect prompt injection and jailbreak attempts in LLM applications, you can use a lightweight 86M-parameter classifier that evaluates user inputs and API responses to identify malicious instructions.

Can I filter malicious prompts across multilingual deployments?

Yes, you can filter malicious prompts across multilingual deployments using a classifier that supports 8 languages and processes inputs in under 2ms on GPU.

How do I secure RAG pipelines against unsafe third-party data?

To secure RAG pipelines against unsafe third-party data, apply a content-filtering model to batch process retrieved documents and block prompt injections before they reach the LLM.

Does prompt injection detection work with HuggingFace deployments?

Prompt injection detection works seamlessly with HuggingFace deployments, allowing you to load the 86M-parameter model directly for fast inference and risk-scoring.

What is the best way to prevent jailbreaks in enterprise chatbots?

The best way to prevent jailbreaks in enterprise chatbots is to deploy a lightweight risk-scoring classifier that filters user prompts and blocks unsafe instructions before processing.

What are the limitations of using an 86M-parameter model for LLM security?

An 86M-parameter model for LLM security offers fast inference under 2ms on GPU but may lack the deep contextual understanding of larger models, requiring batch processing for complex RAG pipelines.
