Understanding and Coding the KV Cache in LLMs from Scratch

KV caches are one of the most critical techniques for efficient inference in LLMs in production. KV caches are an important component for compute-efficient LLM inference in production. This article explains how they work conceptually and in code with a from-scratch, human-readable implementation.It's been a while since I shared a technical tutorial explaining fundamental LLM concepts. As I am currently recovering from an injury and working on a bigger LLM research-focused article, I thought I'd ...
