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.

Multi-Agentic AI for Fairness-Aware and Accelerated Multi-modal Large Model Inference in Real-world Mobile Edge Networks

The paper proposes a Multi-Agentic AI framework to enable fairness‑aware and accelerated inference of large, heterogeneous multi‑modal language models on mobile edge networks. It introduces a Global Planning Agent, a Prompt Scheduling Agent, and multiple on‑node LM Deployment Agents that jointly optimize prompt routing and model deployment using natural language reasoning over telemetry and historical data. Experiments on a city‑wide testbed show a 42.9% reduction in end‑to‑end latency versus a state‑of‑the‑art baseline and an 80.6% reduction versus a full‑activation baseline, while preserving high fairness (Jain's index 0.925).

Routing Without Training: Controllable-Ratio LLM Offloading via Reliability Gating

arXiv:2607. 20481v1 Announce Type: new Abstract: Local-cloud collaboration is a practical way to deploy large language models under resource constraints, but existing methods often rely on trained routers or collaboration-aware finetuning that tie routing behavior to a particular operating regime.

Mind the Delay: Latency-aware Query Routing for Heterogeneous LLM pools

The paper introduces BEA, a fine‑grained estimator that predicts the time‑to‑first‑token (TTFT) for language model queries by replaying token‑batch formation based on current workload snapshots. BEA achieves about 5% error with 0.1 ms prediction time, enabling the latency‑aware router BEAR to balance accuracy, cost, and latency across heterogeneous LLM pools. BEAR outperforms seven baselines, improving utility of on‑target responses by 63% on average and by 30.5% at each arrival rate.
