Carbon-Aware Routing for Function Calling in Edge-Cloud LLM Systems

The paper presents a carbon‑aware routing framework for function‑calling in large language models that distributes queries across a three‑tier edge‑cloud architecture. A lightweight k‑NN predictor estimates accuracy, delay, and power for each edge tier, and real‑time grid carbon intensity is used to route queries to the lowest‑emission tier that can execute them. Experiments on state‑of‑the‑art benchmarks show the framework matches cloud‑level accuracy while cutting operational carbon emissions by an average of four times.

Context Is Not Free: Carbon-Aware LLM Routing for Multi-Turn LLM Web Services across Geo-Distributed Data Centers

The paper introduces CarbonRouter, an online framework that jointly selects the model, GPU type, and region for each query in multi‑turn LLM web services to minimize carbon emissions. It incorporates a cache‑aware carbon cost model that accounts for the history recomputation cost when a conversation is routed to a different deployment, and a lightweight gate that keeps a session on its cached deployment when a move back is likely. Experiments on two real‑world conversation datasets show that CarbonRouter achieves the lowest carbon footprint among evaluated policies, reducing CO₂ emissions by 16.1 % on average and up to 23.1 % for longer sessions, while also improving predicted answer quality and estimated latency.
