SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires nemoguardrails, and includes references (resource) and scripts (resource) components.

What problem does it solve?

This Skill provides a robust framework for adding programmable safety and security rails to Large Language Model (LLM) applications, preventing harmful outputs and misuse.

Core Features & Use Cases

  • Runtime Safety: Implements checks at runtime to ensure LLM interactions are safe and compliant.
  • Jailbreak Detection: Actively detects and prevents prompt injection attacks.
  • Input/Output Validation: Validates both user inputs and LLM outputs for toxicity, PII, and factual accuracy.
  • Fact-Checking & Hallucination Detection: Integrates retrieval mechanisms to verify factual claims and reduce hallucinations.
  • PII Filtering: Masks or removes Personally Identifiable Information from conversations.
  • Use Case: Protect a customer-facing chatbot from generating inappropriate content, revealing sensitive data, or responding to malicious prompts by implementing NeMo Guardrails.

Quick Start

Use the nemo-guardrails skill to define rules for refusing illegal requests in your LLM application.

Frequently Asked Questions about nemo-guardrails

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

FAQPage Schema
How do I prevent prompt injection attacks in my LLM application?

Prevent prompt injection attacks by implementing runtime guardrails that actively detect and block jailbreak attempts. NeMo Guardrails provides programmable security rails using Colang 2.0 DSL to validate interactions and refuse malicious prompts.

Can I filter PII from user inputs and LLM outputs at runtime?

Yes, you can filter PII at runtime using input and output validation rails. The framework masks or removes Personally Identifiable Information from conversations, ensuring your customer-facing chatbot does not reveal sensitive data.

How do I detect hallucinations in LLM responses programmatically?

Detect hallucinations programmatically by integrating retrieval mechanisms for fact-checking. The framework verifies factual claims during runtime validation, reducing hallucinations and ensuring factual accuracy in LLM outputs.

Does NeMo Guardrails support production deployment with GPU acceleration?

Yes, NeMo Guardrails supports production deployment with GPU acceleration. It implements runtime safety and security rails designed to scale, protecting LLM applications from harmful outputs and misuse in production environments.

What is the best way to add safety rails to a customer-facing chatbot?

The best way to add safety rails is implementing programmable validation checks for toxicity, PII, and factual accuracy. This framework secures chatbots from generating inappropriate content or responding to malicious prompts.

Do I need to learn Colang to use programmable guardrails for LLM security?

Yes, you need to learn Colang 2.0 DSL to define programmable guardrails for LLM security. This domain-specific language is used to write rules for runtime validation, jailbreak detection, and safety alignment.
