Validate required models, features, and behavior on your chosen route.
Verify DNS, access, and regional model and API support on both routes.
Confirm private connectivity paths are validated separately for each route.
Ensure OpenAI Private Link or equivalent private connectivity is configured and tested.
Test regional recovery configuration and any recovery to public HTTPS explicitly.
Check provider documentation for current support and any changes.
Confirm not every operation has a suitable secondary route; plan alternatives.

Context

Implementing failover for critical AI workloads between direct OpenAI API and third-party providers.

What it does and when to use it

Before enabling failover for critical AI workloads, validate that all required models, features, and behaviors work on both the primary and secondary routes. This includes verifying DNS, access, regional support, and private connectivity. Also, confirm provider documentation and plan for operations without suitable secondary routes.

Why it works

Ensures that the failover mechanism is robust, secure, and functional, preventing service interruptions or degraded performance when the primary provider is unavailable.

When not to use it

When failover is not critical or when only one provider is available and acceptable.
