The study titled LLM Reasoners: New Evaluation, Library, and Analysis of Step-by-Step Reasoning with Large Language Models introduces a pivotal resource for the assessment and implementation of reasoning methods in LLMs. This work aims to systematize the evaluation of reasoning chains and algorithms across various tasks without relying on expensive human annotations.

• Introduction of AutoRace for automating reasoning chain evaluations.
• Development of LLM Reasoners, a library unifying diverse reasoning approaches.
• Extensive analysis of reasoning approaches, including Chain of Thought (CoT) and Tree of Thought (ToT).
• Insight into the impact of rewards, search strategies, and prompt formats on reasoning.

This paper plays a crucial role in advancing the capabilities of LLMs in generating logic-based reasoning paths, eschewing the black-box nature of AI and moving towards transparent and reliable AI systems. It’s a foundational step for improving AI interpretability and trustworthiness, and could lead the way to more robust AI frameworks that aid human decision-making processes with clearly outlined reasoning steps.
