Guardrails are input/output filters that prevent your AI system from saying things it shouldn't: harmful content, hallucinated facts, leaked PII, off-topic responses, or actions outside its authority. They're the difference between a demo and a production system.
Why this matters
One bad AI output can destroy trust, trigger compliance violations, or go viral. Guardrails are not optional in production — they're the first thing to build, not the last.
