LangChain: Your Swiss Army Knife

In Chapter 1, you were introduced to the various types of generative models available, the most popular architectures, and how they work. Now, this chapter introduces you to LangChain, your Swiss Army knife to building robust applications on top of LLMs and other models. As you build applications beyond just making API calls, you're going to need various components to connect a model to your own data, to external data, and services, and that's what LangChain helps you with. A standard, modular way for you to essentially plug and play with models and various integrations.
