Module 7: RAG Pipelines#

CodeVision Python Training

Contents#

  • Group 1: Why RAG? (Sections 7.1-7.4)

  • Group 2: RAG Architecture (Sections 7.5-7.8)

  • Group 3: Building RAG Pipelines (Sections 7.9-7.12)

  • Group 4: RAG Failure Modes (Sections 7.13-7.16)

  • Group 5: Production RAG (Sections 7.17-7.20)


Welcome to Module 7#

This module teaches you how to build complete RAG (Retrieval-Augmented Generation) pipelines, combining retrieval and generation into reliable AI systems.

It is architecture-focused with working code, showing you how to design, build, and debug RAG systems. By the end of this module, you will understand why RAG systems fail and how to make them robust.

This module builds directly on:

  • Module 1: Python fundamentals (functions, classes)

  • Module 3: LLM Fundamentals (prompting, inference)

  • Module 5: Embeddings & Vector Databases (retrieval, similarity)

  • Module 6: LLM APIs (clients, validation, reliability)
