Chain of Thought in Prompt Engineering: Unraveling Complex Reasoning with Simple Steps

Introduction

Prompt engineering is the art of crafting inputs that guide a language model, like GPT, to generate desired outputs. When the task is straightforward, such as generating a list or summarizing text, a simple prompt might suffice. However, for more complex reasoning tasks, a different approach is needed — one that breaks down the problem into manageable steps. This is where the Chain of Thought (CoT) comes in.

CoT is a technique that encourages a model to “think out loud,” solving tasks in incremental stages rather than rushing to an answer. By guiding the model to reason step-by-step, it achieves a better understanding of nuanced or multi-faceted problems.

The Analogy: Solving a Puzzle

Imagine you’re solving a jigsaw puzzle. If you just grab random pieces and try to fit them together, you may eventually finish, but it’s likely inefficient and frustrating. However, if you begin by sorting the pieces by edge, color, or pattern and then work section by section, the task becomes simpler. This is exactly how chain of thought works in prompt engineering: breaking down a problem into logical parts and solving each…
