Overview

Comprehensive guide for Retrieval-Augmented Generation (RAG) implementation using LangChain. This skill covers the complete RAG pipeline from document processing and chunking, through embedding generation and vector storage, to retrieval strategies, prompt construction, and response generation. Includes advanced patterns like multi-query retrieval, self-querying, parent document retrieval, and production optimizations like caching and batch processing.

Why This Matters

RAG combines the strengths of retrieval systems (access to up-to-date, domain-specific information) with LLMs (natural language understanding and generation). This enables building AI systems that can answer questions based on custom knowledge bases, provide accurate responses with source citations, and reduce hallucination by grounding responses in retrieved documents. RAG is foundational for enterprise AI applications, customer support systems, and research assistants.
