From the Publisher



Why is now the ideal time to explore LangChain with this new book?

We’re witnessing massive innovation in the world of language models. These models wield immense power, though we are still learning how to harness it. This marks a pivotal juncture for the community to start coalescing around a common set of reusable tools that unlock the potential of LLM-powered applications to change the world. While crafting this book, I’ve thought hard about where the added value of generative AI is, how LLM apps can be used, and what kind of innovations could be defining the industry in the coming years, many of which have to do with the tools and integrations that LangChain enables.


What key LangChain developments does this book demystify?

To make LangChain approachable yet empowering, this book explores how LangChain abstracts LLM complexities while exposing knobs for advanced customization. Going beyond the fundamentals of LangChain and simplifying LLM app development through its reusable building blocks, this book also addresses more complex concepts such as agents and chains, which help enhance applications through feedback loops, conditioning techniques, and even fine-tuning. Finally, the book discusses deployment, metrics, and techniques for production use.

What sets this book apart from other LangChain resources?

While there are blog posts and other resources available, they are of mixed quality and perspective. These fragmented introductory resources cover LangChain fundamentals, but this book provides a unique advantage by equipping you with multifaceted mastery. It combines conceptual foundations, real-world implementations, and customization techniques for end-to-end proficiency. The blend of theory and hands-on examples bridges the gap between the basics and expert techniques. Core concepts are elucidated through intuitive explanations and applied case studies spanning diverse domains like information extraction, summarization, and chatbots. This multidimensional coverage of concepts, implementations, and customization delivers distinct value beyond what is offered by the fragmented introductory materials. With this book, you’ll gain advanced skills to deeply understand LangChain and mold it to your applications.
