This second edition tackles the biggest challenge facing companies in AI today: moving from prototypes to production. Fully updated to reflect the latest developments in the LangChain ecosystem, it captures how modern AI systems are developed, deployed, and scaled in enterprise environments. This edition places a strong focus on multi-agent architectures, robust LangGraph workflows, and advanced retrieval-augmented generation (RAG) pipelines.
You’ll explore design patterns for building agentic systems, with practical implementations of multi-agent setups for complex tasks. The book guides you through reasoning techniques such as Tree-of -Thoughts, structured generation, and agent handoffs—complete with error handling examples. Expanded chapters on testing, evaluation, and deployment address the demands of modern LLM applications, showing you how to design secure, compliant AI systems with built-in safeguards and responsible development principles. This edition also expands RAG coverage with guidance on hybrid search, re-ranking, and fact-checking pipelines to enhance output accuracy.
Whether you’re extending existing workflows or architecting multi-agent systems from scratch, this book provides the technical depth and practical instruction needed to design LLM applications ready for success in production environments.

I think this book is living up to the expectation of being beyond documentation – it helps you build things with LangChain. I have read the previous edition and the focus towards Agents in this edition is the best thing that the Author could have done.
I am curious to know how would the one-year code support looks like for the book given books like these become obsolete soon!

A very handy resource to all-things Langchain and Agents. The introduction of Agents and LangGraph has been a welcome change in the current edition – plus, I have read books from both the author’s before and they are excellent writters.

More coverage on Multi-Agent and RAG is a welcome change to the current edition, and it does look like there are some stuff retained from the previous edition as well.

This book includes great insights to various LLM models, providers, and licensing. Limitations, challenges, and opportunities are also covered. The authors make no assumptions and provide helpful information on API key setup, and how to use LangChain.
LangGraph fundamentals are also covered with a specific look at how to build workflows. I especially enjoyed the “Software Development and Data Analysis Agents” section which includes LLM-based software engineering approaches. There is so much great content in this book. I read through it once and will do so again with my fingers on the keyboards so I can start experimenting.
Great resource!

I found this book really helpful for moving past the basics. It covers more ground than just building basic workflows; it also covers leveraging LangGraph, collaborating with different agents, and ensuring that your program is reliable and production-ready. The examples are useful, and developers who want to make the best out of frameworks like LangChain, LangGraph to build dependable LLMs and Agents. Definitely recommend it.

It’s one thing to build an AI prototype.. but this book shows you how to make that prototype work in the real world. You’ll learn how to design multi-agent systems, test thoroughly, and build secure, scalable applications using today’s most popular LLM tools.

A must-read for anyone building real-world LLM applications! Practical, well-structured, and packed with hands-on examples using LangChain, LangGraph, and RAG. Ideal for developers moving from prototype to production.

I’ve just started reading this book and diving into the hands-on labs, but I’m really impressed! As I’m not a Python expert or a professional AI engineer, I find this book easy to follow. The explanations are clear and practical, and the labs make it easy to start building things right away. All needed is explained in a way that makes sense without being overwhelming (at least that’s my view). As I’m progressing through this book, I’m learning not just what the tools do, but how and when to use them in real-world examples. Highly recommended this well-written resource to anyone curious about building stuff with LangChain.

Only a fraction of the way through this book but it has been very helpful for understanding how to use this very powerful framework to accomplish things.
Langgraph has been especially mind blowing after writing scrappy python code to organize everything.
The book is even better when you consider how daunting and unstructured langchain’s documentation can be. Would recommend for developers looking to understand practical design patterns for AI applications.

“Generative AI with LangChain” is a masterclass in building modern LLM apps. It avoids AI marketing fluff and delivers rigorously practical solutions for real-world AI engineering. For anyone serious about building agentic systems that work beyond the demo stage, this book is an essential read. It will not only upgrade your LangChain skills—it will teach you how to think in terms of reliability, observability, and modular AI design.

I just finished reading Generative AI with LangChain, Second Edition by Ben Auffarth and Leonid Kuligin, and I have to say, it’s a solid, practical guide for anyone wanting to build real-world AI applications with large language models (LLMs).
What I really liked is how the authors don’t just focus on the theory but dive deep into hands-on examples, especially around building reliable workflows with LangChain and LangGraph. The chapters on Retrieval-Augmented Generation (RAG) and agent architectures were particularly insightful, showing how to tackle common issues like hallucinations and tool integration in production systems.
That said, I found some parts a bit dense, especially if you’re new to AI development. The advanced agent patterns and error handling sections could use more beginner-friendly explanations or simpler examples to help ease readers into the concepts. Also, given how fast the AI field evolves, it would be great if the book offered more pointers to updated online resources or companion materials to keep up with the latest changes.
Overall, this book strikes a good balance between technical depth and practical advice without overselling the technology. It’s a great resource for developers and data scientists who want to move beyond prototypes and build scalable, production-ready AI systems. If you’re serious about mastering LangChain and building advanced generative AI applications, this book is definitely worth checking out.
