OpenRouter announced its biggest routing algorithm upgrade ever, replacing price-only routing with a blend of realized price, latency, throughput, and error rate per endpoint. Results: TTFT improved 16.9%, throughput 16.3%, capacity errors down 46%, at only 6% higher cost. Routing stays cache-aware, traffic shifts away from failing endpoints in real time, and no code changes are needed. steipete notes unpredictable inference quality was why he used to recommend skipping the middleman.
