An LLM's response generation process can be understood as a "Word Factory" with four key machines: the Chopper (tokenize), the Reader (prefill), the Typewriter (decode), and the Delivery Tape (stream). The Chopper converts text into numerical tokens, which the Reader processes simultaneously, storing notes in a KV cache. The Typewriter then generates the answer token by token, as each new token depends on the preceding ones, utilizing the KV cache to avoid re-processing the entire input. Finally, the Delivery Tape streams each generated token to the user as it's produced, creating the effect of real-time typing. AI
