What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
If a production AI feature can still send inference traffic to a drafting, development, or shared lab endpoint, it is not ready to ship. Keep the feature disabled until the production destination, model identity, request limits, fallback behavior, and release evidence are explicit and verified.
This checklist is a release policy, not a formal industry standard. Taylor Zhu’s DEV Community article lays out the gates and a proposed CI checker; the article says the checker must be run against a repository and its log retained, so the sample should not be treated as a proven tool. The article also discloses that it was prepared as part of MonkeyCode product outreach. OpenAI’s documentation independently supports secure server-side key handling, production request-ID logging, and pinned model versions with evals, but does not certify this entire policy or prescribe one architecture for every team.

What “cut over” must prove
A process starting successfully does not show that its inference route is production-ready. The release must establish where requests go, which model is selected, how request volume is bounded, and what happens when the selected route fails. A production request must not quietly escape those controls by retrying against a lab endpoint or an unreviewed provider.
The six fail-closed release gates
1. Name and allowlist the production origin
Set the production base URL in the production secret or configuration store, and allow only reviewed HTTPS origins. Exclude personal tunnels and development, lab, sandbox, or drafting hosts. Preserve the allowlist commit and the version of the secret-store configuration as release evidence.

2. Make model identity explicit
Configure a model identifier documented by the vendor or by your self-hosted gateway. Reject an empty identifier and moving aliases such as latest or auto when they prevent the release from identifying what it will use. Record the selected identifier, output limit, and the person or role responsible for rotation in the runbook.
OpenAI recommends pinned model versions and evals to improve consistency in prompting behavior and outputs. Pinning does not guarantee identical behavior; it makes the selected version explicit and provides a clearer basis for evaluation.
3. Scan deployable configuration in CI
Run a CI check against the production deployment roots, including rendered or otherwise deployable infrastructure configuration, for forbidden development destinations. A scan of application source alone can miss the configuration that actually determines the deployed route. Retain the CI job log as the receipt for this gate.

4. Bound request and connection budgets
Production configuration should set request and connection timeouts, a maximum retry count, and a per-request token ceiling. Retries must preserve the approved destination and policy. Do not permit unlimited retries or use retry logic to switch the base URL.
5. Keep failure handling inside the approved route
On a production timeout, server error, or quota error, return an explicit failure and record an internal metric. Do not silently route to a drafting host or an unreviewed provider. Add an error-path integration test that demonstrates a denied host is never contacted.
6. Make production traffic identifiable
Record enough non-sensitive metadata to identify the application, selected model, and configured base URL. A stable service identity or user-agent and a production environment tag can make traffic easier to distinguish. Keep a redacted staging log as evidence. OpenAI also recommends logging request IDs in production for troubleshooting; do not put prompts or secrets into logs just to make requests identifiable.

Turn the gates into a release decision
Do not enable the feature if any of these conditions is true: production can still reach a drafting endpoint; the model identity or request budgets are implicit; or fallback can leave the reviewed route. Keep the feature disabled until the required evidence exists.

- Explicit production variables for the approved origin and model identity.
- A client-construction test that fails when the base URL is missing.
- An error-path test proving a denylisted host is not contacted.
- A feature flag that defaults off until the release gates have receipts.
- A runbook entry naming the model-rotation owner.
- A rollback procedure that disables the feature flag rather than redirecting DNS to a sandbox.
Keep durable evidence together: configuration and allowlist changes, CI results, tests, runbook ownership, and redacted diagnostic evidence. The proposed checker in the DEV Community article is only a starting point; run any checker against the actual repository and retain its log before relying on it.

Operational details that support the gates
Keep API keys secret and load them securely in server-side configuration; never expose them in client-side code. Log request IDs in production to help troubleshoot individual API calls. These are vendor-specific recommendations in OpenAI’s documentation, not a substitute for deciding and enforcing your own approved destinations and failure policy.
