Guardrails AI

Guardrails AI is a Python framework that checks what a model says before it reaches users. You add validators for things like PII, toxicity, competitor mentions or JSON structure, and the library retries or blocks outputs that fail.

A hub of community validators saves time, and it can run as a standalone server in front of any model. It helps turn unpredictable text into data your application can trust.

It adds a little latency, so choose only the checks you need.
