Do not enable an AI feature in production until you can prove which inference endpoint and model it will use, bound its requests, and show that errors cannot route traffic back to a development or lab host. A successful app startup is not proof of a production cutover.
The six gates below adapt recommendations from Taylor Zhu’s DEV Community checklist. Zhu discloses that the article was prepared as part of MonkeyCode product outreach; its sample CI checker is a proposal, not a tested artifact or formal industry standard. Treat the gates as a release checklist to validate in your own deployment.
What must be true before enabling the feature
Keep the feature disabled unless production uses an explicitly approved destination and model, request behavior is bounded, fallback preserves the same policy, and the team can produce evidence for those controls. If production can still reach a drafting endpoint, model identity or request budgets are implicit, or fallback can escape the reviewed route, the cutover has not passed.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesMake the feature flag default to off. Enable it only after the release gates below have receipts, and make rollback a matter of turning that flag off—not redirecting DNS to a sandbox.

Six release gates for a fail-closed inference path
1. Name and allowlist the production origin
Set the production base URL through the production secret or configuration store, and allow only approved HTTPS origins. Exclude personal tunnels and development, lab, sandbox, or drafting hosts. Keep the allowlist change and the version of the production secret-store entry as release evidence.
Do not treat an environment variable name such as MODEL_BASE_URL as proof that its value is safe. Validate the resolved value used by the production client against the allowlist.
2. Make model identity explicit
Configure a vendor-documented model identifier or an identifier supported by your self-hosted gateway. Reject a blank value and moving aliases such as latest or auto when they prevent you from knowing what deployment will select. Record the selected identifier, output limit, and a named rotation owner in the runbook.
For OpenAI API use, the API documentation recommends pinned model versions and evals to improve consistency in prompting behavior and outputs. Pinning does not mean behavior can never vary; use evals to check whether a model change remains acceptable for your feature.

3. Scan what will actually be deployed
Run a CI check over production deployment roots, including rendered or otherwise deployable infrastructure configuration, for forbidden development destinations. A source-only scan can miss a host introduced by deployment configuration. Retain the CI job log for the release record.
The checklist’s proposed checker has not been established as tested against a repository. Validate any checker against your actual build and deployment artifacts, and retain its output; do not treat the proposal itself as evidence that your configuration is safe.
4. Bound request and retry behavior
Set explicit request and connection timeouts, a maximum retry count, and a per-request token ceiling in production configuration. Reject unlimited retries. A retry must use the same reviewed destination and policy; it must not silently change the base URL.
Choose the actual limits based on your service’s latency and reliability requirements, then document them. The sample policy’s numerical retry cap is an illustrative configuration choice, not a universal benchmark or published statistic.

5. Fail closed when the reviewed route fails
On a production timeout, server error, or quota error, return an explicit failure and record an internal metric. Do not silently switch to a drafting host or an unreviewed provider. Add an error-path integration test that verifies a denied host is never contacted under these conditions.
Fallback is safe only if it remains inside the same reviewed production policy. If no approved route can serve the request, a visible failure is preferable to an unreviewed route.
6. Make production traffic identifiable without logging secrets
Record enough non-sensitive metadata to identify the application, selected model, and configured base URL. A stable service or user-agent identity and a production environment tag can help distinguish traffic; keep diagnostic evidence redacted.

Turn the gates into release evidence
A checklist is useful only when reviewers can verify the controls in the built and deployed system. Attach or retain evidence for each gate, rather than relying on a developer’s local configuration or a successful process start.
- Production configuration: approved base URL, explicit model identifier, request and connection timeouts, retry limit, token ceiling, and environment tag.
- CI result: scan output for the deployable production roots, including rendered infrastructure configuration.
- Client construction test: a test that fails when the production base URL is missing.
- Error-path integration test: proof that timeout, server-error, and quota handling cannot contact a denylisted host.
- Runbook: model identifier, output limit, and a named owner responsible for model rotation.
- Diagnostic sample: a redacted staging log showing the intended application, model, and route identity without exposing secrets or prompt content.
- Release control: feature flag defaulting off until gates have evidence, with rollback by disabling the feature.
These controls are adapted from Zhu’s checklist and PR recommendations; teams should verify that their own tests and CI checks exercise the configuration that will actually ship.
Compare implementation choices by policy, not vendor
Whether inference runs through a hosted API or a self-hosted gateway, compare the implementation against the same operational questions. This is a policy framework, not a vendor ranking.
Quick Recap
| Check | What to verify |
|---|---|
| Destination control | Are production destinations allowlisted, with development destinations denied? |
| Model control | Is model identity explicit, and is there a named rotation owner? |
| Request bounds | Are timeouts, retry counts, and output limits configured and finite? |
| Failure behavior | Does fallback preserve the same reviewed policy, or fail visibly when no approved route is available? |
| Audit and rollback | Can the team produce configuration, CI, test, runbook, and diagnostic evidence—and disable the feature safely? |
