Where Should Agents Live? Energy-Memory Characterization of Agentic AI for the Edge-Cloud Continuum

Read the original on arXiv AI →

The paper introduces agentic-eCAL, an extension of the Energy Cost of AI Lifecycle metric to evaluate multi‑agent AI workflows across the edge‑cloud continuum. By combining a two‑rate energy model with OSI‑layer transport analysis, the authors quantify that inter‑agent text transfer accounts for only 0.25% of total workflow energy, highlighting that the main energy cost lies in additional inference and context processing triggered by communication. The study uses extensive GPU benchmarks on NVIDIA A100/H100 with 16 open‑weight models and 8 orchestration topologies to validate the metric and explore placement implications.

Energy per Successful Goal: Goal-Level Energy Accounting for Agentic AI Systems

The paper introduces A-LEMS, a framework that measures AI energy consumption at the goal level rather than per model invocation, defining Energy per Successful Goal (EpG) as total workflow energy divided by successfully completed goals. It also proposes the Orchestration Overhead Index (OOI) to quantify the extra energy cost of agentic systems compared to linear execution, revealing significant overheads across various hardware platforms and task families. The study demonstrates that traditional per-inference metrics underestimate the true energy cost of completing user goals in agentic AI workflows.

The Real Cost of Context: Predicting Compute Time and Energy Consumption in LLM Prefill and Decode Phases

The paper investigates how token length affects compute time and energy usage in Large Language Models, focusing on both prefill (input) and decode (output) phases. It finds that decode energy scales linearly with output length, while prefill energy shows both linear and quadratic scaling with input length, highlighting the importance of large input contexts in agentic workflows. The study also demonstrates that compute time can reliably proxy energy consumption when direct measurements are unavailable, providing a framework for more sustainable AI deployment.
