LangChain is an open source project designed to provide interoperability between large language models and external programs.
From the project’s documentation:
Large language models (LLMs) are emerging as a transformative technology… But using these LLMs in isolation is often not enough to create a truly powerful app - the real power comes when you are able to combine them with other sources of computation or knowledge… [LangChain] is aimed at assisting in the development of those types of applications.
This looks like a super interesting project. I’ve talked before about how great it would be to combine ChatGPT with Wolfram Alpha. Well, that seems to be possible with LangChain. This Google Collab notebook and this HuggingFace project both appear to be examples of just that.
