EP352: Hidden states predict AI agent failure

Title: Doomed from the Start: Early Abort of LLM Agent Episodes via a Recall-Controlled Probe CascadeSource: http://arxiv.org/abs/2607.06503v1Summary:This paper introduces a novel framework that uses internal activation probes to detect and early-abort doomed agent trajectories, saving up to 47% of inference compute. This represents a significant efficiency breakthrough for agentic loops, addressing the critical challenge of compute wastage in multi-step agent environments.
