arXiv:2606.02020v1 Announce Type: new Abstract: This paper investigates the entropy dynamics of Chain-of-Thought (CoT) and uncovers a consistent two-phase structure: an Uncertainty Region of exploration transitioning sharply to a Confidence Region of convergence. We demonstrate that the Confidence Region possesses two critical properties: 1) High Reliability -- answers in the confidence region become highly accurate and stable, and 2) High Redundancy -- models generate unnecessary tokens long after reaching the correct answer. These properties unlock more efficient and reliable inference strat
The increasing complexity and opacity of large language models necessitate deeper understanding of their internal reasoning processes to improve efficiency and reliability.
Understanding the 'entropy dynamics' of CoT reasoning provides a framework to optimize AI agent performance, reduce computational waste, and enhance trustworthiness in critical applications.
This research reveals a consistent two-phase structure in CoT, identifying high reliability and high redundancy post-convergence, which allows for targeted optimization rather than brute-force scaling.

More efficient and reliable large language model inference will become standard practice across many applications.
Reduced computational costs for AI systems will enable broader deployment of complex AI agents and lower barriers to entry for AI innovation.
The ability to predict and cut off redundant computation could lead to the development of new, highly resource-efficient AI architectures and on-device intelligence.
