Local AI Agents on Consumer Devices: Energy and Token Overhead
A new study from arXiv (2605.15206) quantifies the resource overhead of running large language model (LLM)-based autonomous agents locally on consumer devices. While local deployment preserves privacy and avoids API costs, agentic workflows—such as multi-step coding or web-based QA—consume significantly more tokens, energy, and time than standard LLM interactions. Measurements reveal increased GPU power draw, temperature, and battery drain due to iterative reasoning, tool use, and failure retries. The paper proposes early termination strategies to save energy when tasks are unlikely to succeed, addressing the inefficiency of wasted compute on consumer hardware.
