about this book
AI Agents in Action, Second Edition, is about building and working with intelligent agent systems: not just creating autonomous entities, but also developing agents that can effectively tackle and solve real-world problems. The book starts with the basics of working with large language models (LLMs) to build assistants, multi-agent systems, and agentic-behavioral agents. From there, it explores the key components of agentic systems: persona, tools and actions, knowledge and memory, retrieval and augmentation, reasoning and planning, and evaluation and feedback. Through practical examples, the book demonstrates how these components empower agents to perform a wide range of complex tasks.
This journey isn’t just about technology; it’s about reimagining how we approach problem-solving. I hope this book inspires you to see intelligent agents as partners in innovation, capable of transforming ideas into actions in ways once thought impossible. Together, we’ll explore how AI can augment human potential, enabling us to achieve far more than we can alone.
