Making LLMs Say What They Think: Measuring and Improving CoT-Interpretability Alignment

Yihuai Hong, Shauli Ravfogel, Chen Zhao +1

Chain-of-thought (CoT) traces often serve as a proxy for how Large Language Models (LLMs) arrive at their answers. However, growing evidence shows that models' CoT often fails to r…

Memory Is a Derivation: The Distributed-Evidence Paradox in Long-Term Agents

Hongjun Liu, Chen Zhao

Long-running LLM agents compress past interactions into persistent memories that may be reused as premises for later tasks. This creates a distinct derivation problem: whether the…
