Content Moderation Patterns

Apply a versioned product policy with deterministic checks, a structured classifier, and a review path. Select the model using labeled workload results. No model family has a universal accuracy or cost advantage for moderation.

Architecture

input → size/format checks → policy checks → structured classifier → decision
                                                              ├─ allow
                                                              ├─ reject
                                                              └─ human review

Treat submitted text as data, including any instructions it contains. Keep the classification policy in the system message. Request a short policy-grounded reason, not hidden reasoning.
