TokenRouter: Efficient Serving System for Token-Level LLM Routing
TokenRouter is a new serving system designed for token‑level routing of large language models (LLMs). It adopts a request‑centric programming model and launches a dedicated subserver for each LLM, using delayed‑batching schedulers whose hyperparameters are derived from a throughput model. Across various routing algorithms, workloads, and model pairs, TokenRouter delivers 2.01‑64.15× higher decoding throughput than existing systems, markedly improving the efficiency of token‑level LLM inference.

Scorpio: Serving Right Requests at the Right Time for Heterogeneous SLOs in LLM Inference
Scorpio is an LLM serving system that optimizes for heterogeneous Service Level Objectives (SLOs) such as Time to First Token (TTFT) and Time Per Output Token (TPOT). It uses adaptive scheduling across admission control, queue management, and batch selection, featuring a TTFT Guard that reorders requests by least-deadline-first and rejects unattainable ones, and a TPOT Guard that employs VBS-based admission control and a credit-based batching mechanism. Predictive modules support both guards, and evaluations show Scorpio can increase system goodput by up to 14.4× and improve SLO adherence by up to 46.5% under high load compared to state-of-the-art baselines.
