Building AI Agents with LangChain, LangGraph & CrewAI: The Complete Hands-On Guide to Building Autonomous AI Agents with Python, LLMs, OpenAI, RAG, Me

By Teli Publications and Sankalp Gupta

Build the next generation of AI applications.

Artificial Intelligence is entering a new era.

Instead of simply answering questions, modern AI systems can reason, plan, use tools, search the web, remember information, collaborate with other agents, and complete complex tasks autonomously. These intelligent systems are known as AI Agents, and they are rapidly becoming one of the most valuable skills for developers, engineers, and AI professionals.

If you already know basic Python-or are ready to learn-you can start building powerful AI agents today.

Building AI Agents with LangChain, LangGraph & CrewAI is a practical, project-based guide that takes you from the fundamentals of AI agents to designing production-ready autonomous systems using today's most popular open-source frameworks.

Unlike books that only explain theory, this guide focuses on building real applications through clear explanations, practical examples, and complete Python implementations.
