What is LangChain?

LangChain is a framework for building LLM-powered applications. The framework consists of components that are modular and easy to use. The components are abstractions for working with LLMs, whether you use the rest of the framework or not. Moreover, LangChain contains Off-the-shelf chains. You use these chains to combine several components. This approach makes it easy to develop complex applications.

LangChain has a lot of functionalities, and it’s hard to keep track as a beginner. The framework currently contains six main modules, and in this book, we want to explain the core features of each module. This approach helps you to understand the framework from the ground up in an easy way.
