About Guardrails.ai

Guardrails is a Python framework that helps build reliable AI applications by running Input/Output Guards on LLMs. These guards detect, quantify, and mitigate specific types of risks (e.g., toxicity, hallucination). Guardrails also enables generating structured data from LLMs. The framework integrates with the Guardrails Hub, a collection of pre-built validators that can be combined into custom guards. It is designed to improve the safety, accuracy, and reliability of AI applications in production.

Key Features

Input/Output Guards that intercept and validate LLM inputs and outputs
Detection, quantification and mitigation of specific risk types (e.g., toxicity, hallucination)
Integration with Guardrails Hub: a collection of pre-built validators for common risks
Structured data generation from LLMs
Python framework for production-grade reliability

Pros & Cons

Pros
  • Open-source Python framework with a focus on reliability

FAQ

What is Guardrails?
Guardrails is a Python framework that helps build reliable AI applications by running Input/Output Guards on LLMs. These guards detect, quantify, and mitigate specific types of risks.
What is Guardrails Hub?
Guardrails Hub is a collection of pre-built measures (validators) for specific types of risks. Multiple validators can be combined into Input and Output Guards that intercept LLM inputs and outputs.
How does Guardrails help generate structured data?
Guardrails includes functionality to generate structured data from LLMs, ensuring outputs conform to expected formats and are validated against defined risks.
