Doomed from the Start: Early Abort of LLM Agent Episodes via a Recall-Controlled Probe Cascade
arXiv:2607.06503v1 Announce Type: new Abstract: Large language model (LLM) agents solving multi-step tasks frequently commit to trajectories that are doomed to fail, yet continue to consume substantial inference compute before the failure becomes observable. We show that failure is predictable early from the agent's internal representations: lightweight per-round probes on hidden activations anticipate eventual episode failure as early as the first interaction round, where scorers reading only the agent's observable behavior are barely better than chance. We turn this signal into a practical a
Advances in understanding LLM internal representations and the practical need to optimize compute for increasingly complex agentic tasks are driving this development.
This research offers a method to significantly reduce wasted computational resources in LLM agent deployments, making sophisticated agents more economically viable and scalable.
LLM agents can now be designed with internal 'self-correction' mechanisms that prevent expensive failures, leading to more efficient and reliable autonomous systems.
