Step 1 of 15 · Intro

Design a guardrails and moderation pipeline

Check every message before the model and every answer after it, within a latency budget, with a human review queue and a plan for when the checks fail.

How it works

• ›Cheap rules and a verdict cache take the bulk of traffic, so the expensive classifiers only see what is new.
• ›A classifier fleet scores messages and answers; two thresholds turn scores into allow, block or send-to-a-human.
• ›A queue and workers record decisions and feed the human review queue off the critical path.
• ›When the classifiers fail, you must pick fail open or fail closed deliberately, per use case.
• ›A model you host yourself keeps the product alive if the provider has an outage.

What you'll build

1. The moderation API and its data model
2. A limiter, classifier fleet, gateway and model in a chain
3. Fast rule checks and a cache for repeated checks
4. A queue and workers for logging and human review
5. A design that survives a lost classifier, a provider outage, a cold cache and an abuse flood
