Part VIII — Embeddings Become Infrastructure

Not a RAG chatbot

The obvious capstone would be “build a RAG system.” It would also be the wrong one — a RAG system exercises maybe a third of this book and hides the rest inside a framework.

The capstone is an Embedding Observatory: a runtime whose job is to know things about representations. It ingests text, documents, and queries under one or more embedding models, and it exposes not just vectors but the geometry, neighborhoods, distributions, evaluations, calibrations, versions, and bridges that the book spent 23 chapters building tools for.
