Dual-process architecture in production

“Dual-process” in software describes a workflow pattern, not a claim that AI reproduces human cognition. A bounded decision step may route a request; a generative model may be used when free-form explanation or open-ended reasoning is required.

Input → typed decision → validated threshold? → continue
                              └─ uncertain/high impact → human review or safe fallback

Measure false positives and negatives, end-to-end latency and cost on representative traffic. Do not assume a gate is correct or faster by design. For risky tool calls, combine deterministic policy checks, least privilege, conservative thresholds, abstention and human review. Never let an unvalidated confidence score alone authorize an irreversible action.

Model routing

The share of traffic that can be handled by a decision layer depends on the workload and must be measured. Do not generalize promotional percentages without public methodology and reproduced results.

FAQ

Do I need Jev access for dual-process?

No. The workflow can use a validated classifier or decision model suited to your task.

Can a decision model be the only safety gate for a tool?

Not for consequential or irreversible actions unless you have validated the complete control system. Combine safeguards, abstention, least privilege and human review where appropriate.
