First Look at Reasoning From Scratch: Chapter 1

This article presents the first chapter of a book on reasoning in Large Language Models (LLMs). It defines reasoning in the context of LLMs, distinguishes it from pattern matching, and introduces key methodologies like inference-time scaling and chain-of-thought reasoning. The chapter lays the groundwork for a practical, hands-on approach to implementing reasoning techniques from scratch in subsequent content.
