📖 Full Retelling
Researchers presented a new approach on arXiv (paper arXiv:2505.11824v3) to improve the reliability of Chain‑of‑Thought (CoT) reasoning in language models. They suggest augmenting every reasoning step with a latent veracity variable that indicates the correctness of that step, and introduce Veracity Search (VS), a discrete search algorithm that efficiently explores this expanded space. The work addresses the problem that current CoT chains often contain inaccuracies, thereby weakening model performance and trustworthiness. By detecting and correcting errors in stepwise reasoning, the authors aim to make large language models more transparent and reliable.

Abstract: Chain-of-Thought (CoT) reasoning has advanced the capabilities and transparency of language models (LMs); however, reasoning chains can contain inaccurate statements that reduce performance and trustworthiness. To address this, we propose to augment each reasoning step in a CoT with a latent veracity (or correctness) variable. To efficiently explore this expanded space, we introduce Veracity Search (VS), a discrete search algorithm over
