TokenRouter: Efficient Token-Level LLM Routing via Async Handoffs & Delayed Batching
This article analyzes TokenRouter, a NeurIPS 2026 system that enables efficient token-level LLM routing through a request-centric programming interface, asynchronous model handoffs with state preservation, and throughput-optimized delayed batching, demonstrating 2-64x throughput gains over baselines across multiple routing algorithms and workloads.
