zudyog AI - AI RAG Mastery Series

Zudyog is home to the RAG Mastery Series — an 11-book series on building production-grade Retrieval-Augmented Generation systems with Python.

We teach you to go beyond toy chatbots: real vector databases (Qdrant, FAISS, ChromaDB), hybrid search, chunking strategies, reranking, RAGAS evaluation, LangGraph agents, multi-tenant architecture, and GDPR-compliant deployment on AWS.

4 core books are available now, walking through one system (ShopBot) built from scratch to production scale. 7 companion books release quarterly starting November 2026, covering agentic AI, MCP servers, context engineering, guardrails, automation, and cloud infrastructure.

Book 1 — The AI Engineer — is completely free.

On this channel: tutorials, walkthroughs, and deep dives that pair with the books, for developers who want to build AI systems that answer from evidence, not guesswork.
