Description
Some parts of this course and its content were created or assisted using Artificial Intelligence tools to enhance clarity, structure, and learning efficiency.This course provides a complete and practical guide to mastering Retrieval-Augmented Generation (RAG) using the powerful LlamaIndex framework. Designed for developers, data scientists, and AI enthusiasts, this training will take you from the foundational concepts of retrieval systems to the advanced techniques required to build high-performance, knowledge-aware AI applications.You will begin by understanding the limitations of Large Language Models and why RAG has become essential for improving accuracy, reliability, and factual grounding. Through hands-on lessons, you will learn how to configure your environment with GitHub Codespaces, choose the right LLM provider, work with vector databases such as Qdrant, and upload and index your own datasets.The course then dives into the core architecture of LlamaIndex, covering ingestion pipelines, query pipelines, chunk optimization, metadata extraction, semantic segmentation, hybrid retrieval, and advanced evaluation techniques. You will also explore modular RAG design, post-retrieval enhancements, reranking strategies, and methods to build scalable AI systems capable of handling real-world data.By the end of this course, you will be able to design, build, optimize, and evaluate complete RAG systems from scratch. You will gain both theoretical understanding and practical experience, enabling you to create AI tools, chatbots, assistants, and enterprise-level applications that leverage external knowledge efficiently and intelligently.This is the ultimate 2025 guide to building cutting-edge RAG-powered AI systems with LlamaIndex.
