DESCRIPTION Large language models (LLMs) like GPT, BERT, and T5 are revolutionizing how we interact with technology — powering virtual assistants, content generation, and data analysis. As their influence grows, understanding their architecture, capabilities, and ethical considerations is more important than ever. This book breaks down the essentials of LLMs and explores retrieval-augmented generation (RAG), a powerful approach that combines retrieval systems with generative AI for smarter, faster, and more reliable results. It provides a step-by-step approach to building advanced intelligent systems that utilize an innovative technique known as the RAG thus making them factually correct, context-aware, and sustainable. You will start with foundational knowledge — understanding architectures, training processes, and ethical considerations — before diving into the mechanics of RAG, learning how retrievers and generators collaborate to improve performance. The book introduces essential frameworks like LangChain and LlamaIndex, walking you through practical implementations, troubleshooting, and optimization techniques. It explores advanced optimization techniques, and offers hands-on coding exercises to ensure practical understanding. Real-world case studies and industry applications help bridge the gap between theory and implementation. By the final chapter, you will have the skills to design, build, and optimize RAG-powered applications — integrating LLMs with retrieval systems, creating custom pipelines, and scaling for performance.

LangGraph in Action: A Hands-On, Step-by-Step Guide to Building Stateful AI Agents in Python Unlock the power of LangGraph-a modern extension of LangChain-to orchestrate intelligent, stateful AI workflows. Designed for intermediate Python developers, this book teaches you how to build robust, context-aware agents that remember past interactions, make dynamic decisions, and scale in production. Managing state is crucial for real-world AI applications. LangGraph's graph-based approach lets your agents carry information across turns and sessions, so they never lose track of user preferences or workflow progress. You'll learn not only why persistent context matters but exactly how to implement it. Dive straight into code with a practical, step-by-step format: LangGraph Fundamentals: Build your first LLM-driven Python agent, then transform it into a LangGraph flow with nodes and edges. Graph-Based Workflows: Structure complex logic as reusable graphs, enabling loops, branches, and conditional paths beyond simple chains. Stateful AI Applications: Implement persistent session state so each node can access and update memory, powering long-running and multi-step processes. Agent Orchestration & Scaling: Coordinate multiple agents, integrate external APIs, and apply best practices for performance and horizontal scaling. Real-World Case Studies: Follow hands-on examples-from context-aware chatbots to customer support and data-analysis pipelines-to see how LangGraph solves practical challenges. Each chapter builds on the last, reinforcing concepts with working examples, clear explanations, and downloadable code. By the end, you'll have the skills to design, implement, and deploy production-grade AI agents with Python. Whether you're automating customer support, building autonomous data pipelines, or exploring new AI workflows, LangGraph in Action gives you the roadmap and the hands-on practice to turn ideas into intelligent, scalable solutions.
