Chain-of-Thought (CoT) prompting is a technique in prompt engineering that enhances large language models (LLMs) by breaking down complex tasks into smaller, logical steps to achieve more accurate and transparent results. Originating from a Google research paper, CoT prompting improves LLM performance on tasks like solving math problems and logical reasoning by emulating human problem-solving processes. Key techniques include Zero-Shot, Few-Shot, Automatic, Multimodal CoT, and Self-Consistency Sampling, each offering unique advantages in various contexts. CoT prompting stands out by providing greater accuracy, transparency, and improved symbolic reasoning compared to standard and few-shot prompting methods. Additionally, it distinguishes itself from other strategies like Tree-of-Thought prompting, which explores multiple solution paths simultaneously. CoT prompting's structured approach not only enhances the reliability and traceability of LLM outputs but also encourages creativity in problem-solving, making it applicable in diverse scenarios from research to real-world applications.
