LangChain is a framework for developing applications powered by #LargeLanguageModel s (#LLM s). Just what does this mean? What is in this library and why? In this video, I start by contrasting #ChatGPT the popular web app with ChatGPT the developer API in order to point out some very basic tasks and problems that many people will quickly encounter when creating applications like chatbots. This is a great lens through which to start explaining not only what functionality is in LangChain but why it is in there in the form that it is and how you might decide to use (or not to use) such a tool.
