LangChain is a framework and platform for LLM application development. They aim to provide an abstraction that allows your code to easily pivot and mix and match various pre-processors, language models, stores and agent platforms. The library itself is enormous in breadth. We will take a look at which abstractions are provided and how to use them. We will ultimately answer whether their abstractions work, when to use it, and when to not bother.
