How does latency-aware routing optimize global ChatGPT inference infrastructure?

Latency-aware routing directs requests to the fastest available region or GPU cluster based on real-time network and compute conditions.

Global ChatGPT systems operate across multiple data centers. Latency-aware routing ensures requests are sent to the region that minimizes total response time, considering network RTT, GPU availability, and queue depth.

Routing systems continuously monitor infrastructure health metrics and dynamically adjust traffic distribution. If one region becomes overloaded, traffic is shifted to alternative clusters even if they are geographically farther.

This system balances latency optimization with load balancing and fault tolerance.
