It works by tracking token log-probabilities, token counts per step, and token overlap between steps — signals already produced during normal inference — and feeds them into a gradient-boosted XGBoost classifier. Evaluated on web question answering (FRAMES, SimpleQA) and coding (SWE-Bench Verified), AgentStop reduces wasted energy by 19–23% with less than a 5% drop in task utility. The supervisor itself costs under 0.01 mWh per inference call. The project is open source and was accepted at ACM CAIS 2026. ## Full article daily.dev links to this article rather than hosting it.
