How to route agent requests when model capability, policy, cost, and latency conflict
Rama_Surasani_ · reddit · 2026-09-23
A developer working with nRouter on multi-model routing asks how to design agent request routing when models differ in capability, cost, and latency, and requests may need tool calls or structured output.
Key questions:
- Apply hard eligibility checks for capability and policy first, then optimize cost/latency — or combine signals into one weighted routing score?
- For dynamic routing, what prevents provider latency shifts from causing route flapping: rolling windows, hysteresis/cooldown, or an evaluation gate?
