AI Interview Series #4: KV Caching Explained

This article, part of an AI interview series, focuses on the practical challenge of LLM inference slowdown as the sequence length increases. It highlights the inefficiency related to recomputing key-value pairs for attention mechanisms in each decoding step. The article likely delves into how KV caching can mitigate this issue by storing and reusing previously computed key-value pairs, thereby reducing redundant computations and improving inference speed. The problem and solution are relevant to anyone deploying LLMs in production environments.

• •KV caching is a technique to optimize LLM inference.
• •It addresses the slowdown caused by recomputing key-value pairs.
• •Storing and reusing KV pairs improves inference speed.
