11-5: RAG Architecture Economics
Triage embedding costs, calculate vector DB pricing at scale, and execute ruthless chunking strategies to preserve margins.
🎯 What You'll Learn
- ✓ Execute a Total Cost of Ownership (TCO) model for RAG
- ✓ Determine Vector DB pricing thresholds
- ✓ Minimize LLM context-window exhaustion via semantic reranking
RAG is a Search Problem, Not an AI Problem
Retrieval-Augmented Generation (RAG) is currently the default architecture for enterprise AI. However, most teams drastically mismanage the unit economics by treating RAG as an LLM problem.
RAG is fundamentally an Information Retrieval (Search) problem. If your vector database retrieves the wrong documents, your LLM will generate the wrong answer—regardless of whether you use Llama-3 or GPT-4o.
The economic failure state of RAG is "Context Stuffing": retrieving 50 irrelevant documents and shoving them all into the LLM context window, hoping the AI figures it out. This balloons token costs and destroys profit margins.
The percentage of tokens placed into the LLM context window that actually contribute to the final answer.
The monthly recurring cost of maintaining billions of vectors in memory.
