Key Points
- The article argues against treating a single LLM provider as a highly available utility, highlighting the risk of outages, rate limiting, and 5xx errors, and advocates decoupling the application from vendor lock-in for enterprise-grade AI.
- It introduces the concept of a Unified Routing Plane, implemented via an API gateway like OpenRouter, which automatically reroutes requests to secondary models or alternative infrastructures to maintain availability and performance.
- It promotes Declarative JSON Routing (Infrastructure as Data), enabling routing policies to be managed dynamically by Platform or FinOps teams without redeploying application code.
- It provides a production-ready routing payload example showing model, messages, provider order, and fallbacks to illustrate how multi-provider routing is configured in practice.
