A new research paper investigates the effectiveness of verbose chain-of-thought (CoT) prompting in large language models. The study presents evidence suggesting that the semantic content and reasoning steps within CoT, rather than mere length, are the primary drivers of improved accuracy. Experiments across 25 models indicate that extra tokens have a minimal impact on accuracy when the reasoning plan remains the same, and controlled interventions show that while verbosity can offer modest gains, these are dependent on the quality of the prose and the reasoning content, not just token count.

IMPACT This research suggests that optimizing LLM reasoning prompts should focus on the clarity and semantic value of intermediate steps, rather than simply increasing token length.
