Open-source Python framework that runs configurable Input/Output Guards to validate large language model responses.
Guardrails is an open-source Python framework, published on GitHub by Guardrails AI, that runs Input/Output Guards around calls to large language models. Each guard checks a specific risk category, such as hallucinated claims, leaked personal data, or unsafe content, and can block, flag, or rewrite a response before it reaches the end user.
Developers compose guards drawn from a community-maintained hub into a validation pipeline, giving applications a reusable layer for catching and correcting unreliable model output.
