What it's used for

Guardrails AI is used to validate and correct LLM outputs against defined rules, catching issues like hallucinations, PII leakage, off-topic responses, and format violations before they reach users. It wraps your LLM calls with validators that automatically re-prompt the model when outputs fail checks.

Getting started

Install with `pip install guardrails-ai` and run `guardrails hub install hub://guardrails/regex_match` to add validators from the Guardrails Hub. Create a Guard object with your chosen validators, then call `guard()` with your LLM function and prompt. Failed validations trigger automatic retries with corrective instructions.
