	Title: Energy-Aware Edge-Cloud Vision-Language Inference Abstract: The growing deployment of Vision-Language Models (VLMs) at the edge raises important challenges in balancing energy consumption, latency, and inference quality. While cloud-hosted VLMs provide high prediction accuracy, they incur communication overhead and higher energy costs, whereas edge execution offers lower latency but is constrained by limited computational resources. Moreover, the energy required for inference depends on the complexity of both visual inputs and user queries, making static execution policies inefficient. We present a lightweight energy-aware routing framework for two-tier edge-cloud multimodal inference. INAR-VL leverages lightweight image and text complexity indicators to adaptively select the execution location and VLM, processing simple requests locally while offloading only energy-intensive or reasoning-intensive cases to the cloud.
