KV Cache Explained: How Transformers Optimize Attention Computations

This article delves into the internal workings of KV cache, a crucial mechanism that enables transformer models to avoid redundant computations during attention calculations. It explains how this technique optimizes the generation of sequential tokens by storing and reusing previously computed key and value states. The explanation highlights the efficiency gains achieved by preventing repeated calculations for each new token. AI
