about this book
AI Agents in Action 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: retrieval systems for knowledge and memory augmentation, action and tool usage, reasoning, planning, evaluation, and feedback. The book demonstrates how these components empower agents to perform a wide range of complex tasks through practical examples.
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 that were once thought impossible. Together, we’ll explore how AI can augment human potential, enabling us to achieve far more than we could alone.
