Recommend a free AI book: Agentic AI 漫游指南 (The Hitchhiker’s Guide to Agentic AI).

I just started reading it, and I find it quite different from many “AI introductory guides.” Although it covers basics, the author clearly doesn’t spend most of the book on concepts that have been repeated over and over. Instead, it goes all the way through Reinforcement Learning (RL), Reasoning, and Evaluation before finally getting to Agentic AI. So it’s more like a book that helps you understand how AI works, rather than a manual teaching you “how to use AI tools.”

If you’re no longer satisfied with just using ChatGPT, Claude, or Cursor, and want to go deeper into why AI can reason, how it is trained, how it is evaluated, and how Agents actually run, this book is well worth keeping.
