Prompting

Chain-of-Thought Prompting

Chain-of-thought prompting (CoT) asks models to show reasoning. Simple phrasing: 'Let's think step by step' or 'Show your work'. CoT dramatically improves accuracy on reasoning tasks. CoT can be explicit (shown in output) or implicit (internal). CoT is particularly effective for math and logic. CoT sometimes hurts on simple tasks. CoT is a high-impact technique.
