Model routing

OpenRouter.

Choose the model.
Keep one connection.

We compare suitable models and use OpenRouter when a workflow benefits from switching between providers.

Why it helps

  • Accesses models from different providers through one API.
  • Makes side-by-side testing and fallback easier.
  • Your team can choose the quality, speed and cost that fit each task.
  • A fallback model can keep a workflow moving during provider interruptions.

Compare models through one connection

OpenRouter offers a common interface to models from different providers. We use it when a project benefits from comparing options or managing model routing in one place. The business task still comes first: every candidate receives the same brief and representative test inputs.

Keep routing choices explicit

We define which models and providers are acceptable, how requests are configured and what should happen when a service is unavailable. A fallback response needs testing too. Different models can interpret an instruction differently, even when the surrounding application sends the same request.

Review the whole operating picture

A fair comparison covers output quality, latency, usage cost and the selected providers’ data handling. One successful example does not establish reliability. We keep a repeatable set of checks so a routing or model change can be evaluated before it affects the live workflow.
