The study delves into the impact of reasoning step length on the Chain of Thought (CoT) performance in large language models (LLMs). It finds that increasing reasoning steps in prompts improves LLMs’ reasoning abilities, while shortening them diminishes these capabilities. The study also highlights the task-dependent nature of these findings and emphasizes the importance of reasoning length over factual accuracy.

Impact of Reasoning Step Length on Chain of Thought Performance in Large Language Models
Large language models (LLMs) are at the forefront of problem-solving and reasoning tasks. The Chain of Thought (CoT) prompting technique mimics human sequential reasoning and has shown remarkable effectiveness in challenging scenarios. However, a detailed understanding of CoT’s mechanics is still needed, leading to experimental approaches for improving its efficacy without a structured framework.
Research and Key Findings
The recent study investigated the relationship between the length of reasoning steps in prompts and the effectiveness of LLMs in problem-solving. The research team conducted controlled experiments and found that lengthening reasoning steps in prompts significantly enhances LLMs’ reasoning abilities across multiple datasets. The study also revealed that even incorrect rationales could yield favorable outcomes if they maintained the required length of inference.
The key findings of the study include:
- Direct linear correlation between step count and accuracy for few-shot CoT
- Lengthening reasoning steps in prompts enhances LLMs’ reasoning abilities
- Incorrect rationales can lead to favorable outcomes if they maintain the necessary length of inference
- The effectiveness of increasing reasoning steps is contingent on the task’s complexity
- Enhancing reasoning steps in zero-shot CoT settings leads to improved LLM accuracy
