The short answer
Model routing is valuable when task-specific quality, speed, or cost differences are meaningful and the routing logic can be evaluated.
One model rarely wins every task. Routing lets a product match the job to an appropriate capability, latency, and cost profile.
Routing is useful when the models behave differently in ways users can feel. If the results are indistinguishable, the complexity may not pay for itself.
Teams need to know which model handled a request and why. Otherwise, routing becomes another hidden source of inconsistent behavior.

A faster model can change the economics of a product. It does not, by itself, create a product people keep.
Agent-ready APIs are not only about endpoints. They need clear states, predictable errors, and safe ways to undo work.
Model launches are becoming less like events and more like continuous product operations.
