About this course

Large Language Models are incredibly powerful, but they often struggle with outdated information and hallucinated facts when asked about private data. Retrieval-Augmented Generation (RAG) solves this by connecting LLMs directly to your own knowledge bases, ensuring accurate and verifiable responses. In this comprehensive text-based course, you will master the foundational concepts and practical architectures needed to design and implement your own RAG systems. You will transition from understanding basic LLM limitations to conceptualizing and structuring a complete, data-enriched AI pipeline. What you'll learn: 1. Understand the core mechanics of Retrieval-Augmented Generation and how it differs from fine-tuning. 2. Explore document ingestion, text chunking strategies, and embedding generation. 3. Utilize vector databases for efficient semantic search and information retrieval. 4. Implement prompt engineering techniques to ground LLM responses in retrieved context. 5. Evaluate RAG performance and address common failure modes like hallucinations. 6. Practice designing robust RAG architectures using modern patterns like hybrid search. You will start with essential terminology and the conceptual architecture of RAG, then progress step-by-step through data preparation, vector databases, and retrieval strategies. This course is designed for beginners, developers, and AI enthusiasts who want to understand how modern search-augmented AI systems work, with no advanced programming or machine learning background required. Start reading today to unlock the power of context-aware artificial intelligence.
