What is
Chain of Thought?

A prompting technique where the model is asked to reason step by step before answering.

Definition

Chain-of-thought prompting explicitly asks the model to write out intermediate reasoning before giving a final answer. This significantly improves performance on math, multi-step logic, and complex retrieval tasks. Modern reasoning models (Claude with extended thinking, OpenAI o1) automate this with hidden reasoning tokens.

Example

For a math problem, the prompt says "Think step by step before answering" — the model writes its reasoning, then the final answer.

How Vedwix uses Chain of Thought in client work

We use it selectively; for simple tasks it adds latency and cost without quality gains.
