From Prompt to Prediction: Understanding Prefill, Decode, and the KV Cache in LLMs

Here's a podcast episode description: **Ever wonder what's actually happening inside a large language model between the moment you hit "send" and when the first word appears?** In this episode, we pull back the curtain on the two distinct phases of LLM inference — prefill and decode — and explore the surprisingly elegant mechanism known as the KV cache that makes it all work at scale. Whether you're an AI practitioner, a curious developer, or just someone who wants to understand the machinery behind the tools reshaping our world, this episode will change the way you think about how language models "think."
