Perplexity's guide explains what AI guardrails are, how they work at three checkpoints, and gives seven practical examples of guardrails for large language models.

## Evidence

Verbatim from https://www.perplexity.ai/hub/blog/ai-guardrails:

> AI guardrails are safeguards that limit what an AI system accepts or does. They can be built into a model through safety training, applied as checks around the model, or enforced through software.
