What is
Guardrails?
Runtime checks that validate or filter LLM inputs and outputs against policies.
By Anish· Founder · Vedwix
·Definition
Guardrails are programmatic rules — regex, classifiers, secondary LLM checks — that enforce behavioral constraints on an AI system. They block PII leaks, harmful content, off-topic responses, or policy violations before output reaches users. Guardrails are belt-and-suspenders to alignment training, not a replacement.
Example
A finance assistant has a guardrail that refuses any output containing a specific account number format.
How Vedwix uses Guardrails in client work
Always layered. Alignment training is the first defense; guardrails are the second.
