About this lesson

Ever wondered how large language models like GPT respond so fast without recomputing everything from scratch? In this video, I break down the Key-Value (KV) Cache a crucial optimization used in transformer models to speed up inference. We’ll cover: - What the KV cache is - Why it’s needed in autoregressive models - How it reduces computation during token generation
