Latency-aware AI model routing treats response time as a selection constraint or ranking signal. Interactive requests may require a fast first response, while background tasks can tolerate slower models when they provide better quality or lower cost.
A router can use measured latency, time budgets and service health to choose among eligible models. It should distinguish normal speed from provider slowdowns and retain a fallback when the preferred model cannot respond in time.

Latency-aware AI model routing chooses which model should handle a request partly by considering how quickly a response is needed. A fast model may serve an interactive request, while a slower model can handle background work when extra time is acceptable.
For example, a voice assistant can route a simple command to a model expected to answer within a fraction of a second. A long document review can go to a different model, and the router can switch again if that service becomes unusually slow.
