KV Cache from Scratch in Python

Understanding the key optimization that makes LLM inference fast

KV Cache

TL;DR

KV caching avoids redundant computation during autoregressive generation by storing the key and value tensors from previous tokens. Without it, generating N tokens would require O(N²) attention computations. I'll implement a KV cache from scratch in pure Python/NumPy, then show how it integrates with a transformer decoder.
