Why use Chain of Thought
Chain of Thought (CoT) guides AI models to articulate their reasoning steps explicitly before delivering a final answer. This approach significantly improves their ability to solve complex and multi-step problems.
CoT leverages the model's inherent capacity to follow logical sequences. It involves prompting the model to decompose a problem into a series of intermediate, manageable steps, mimicking human cognitive processes. This technique is particularly beneficial for tasks requiring deduction, inference, mathematical calculation, or complex analysis. Its effectiveness depends on the model's underlying capability and appropriately detailed prompting. Over-reliance on model-generated steps without verification can still introduce errors.
CoT enhances accuracy, interpretability, and user trust by making reasoning traceable. It allows models to tackle intricate problems like math word problems, commonsense reasoning, or code debugging that direct one-step answers often fail at. Crucially, it helps models generalize better to unseen problems within their capability limits by structuring the solution process. Ultimately, CoT expands the practical utility and reliability of large language models for demanding analytical tasks.
