From Prompt to Response

An End-to-End Journey Inside LLM and RAG Systems

Welcome

A technical deep-dive into the full LLM stack, from training and alignment through serving, retrieval, evaluation, and production operation. Every chapter is built around a single question that unlocks a layer of the system.

Designed for engineers and researchers who work with LLM systems and want to understand not just how to use them, but how they behave end-to-end under real constraints.
