Generative AI (A Complete Guide to Large Language Models, Prompt Engineering, RAG, LangChain, AI Agents, Multimodal AI, and Real-World Applications) by Aravind choudhary

Generative AI is a practical and comprehensive guide to understanding and building modern AI applications powered by Large Language Models (LLMs) and generative AI technologies.

The book starts with the fundamentals of Artificial Intelligence and Generative AI and gradually progresses to advanced concepts such as Large Language Models, prompt engineering, embeddings, vector databases, Retrieval-Augmented Generation (RAG), LangChain, AI agents, tool calling, multimodal AI, and Agentic AI.

Readers will learn how to work with modern AI models, design effective prompts, build intelligent chatbots, process documents, create question-answering systems, integrate external tools and APIs, and develop real-world AI applications using Python and popular AI frameworks.

The book emphasizes practical implementation and real-world use cases, making it suitable for learners who want to move beyond AI theory and build useful Generative AI solutions.
