TRACE-ROUTER is a new routing framework that addresses a fundamental mismatch in enterprise LLM deployment: existing per-call routers cannot correctly attribute feedback to individual routing decisions in long-horizon agentic workflows. The system assigns each task to a single model at admission using a contextual bandit and updates its policy using the task's terminal reward, jointly optimizing accuracy and latency. On tau2-Bench, it outperforms latency-matched interpolation between individual models by 7-8 accuracy points; on Terminal-Bench it achieves 7.1 higher accuracy points than the strongest single-model baseline with 36% lower latency.
