The Entire Process From Prompt to First Token
shbhmrzd · hn · 2026-07-12
This article explains the entire process from inputting a prompt to the model outputting the first token, focusing on the fundamental mechanisms of LLM training and inference.
It details how models map text to tokens and generate the next token step-by-step during inference, helping readers understand the underlying computation and sampling processes behind what appears to be an instant response.
