That's exactly what LangChain does.Įssentially, it allows your LLM to reference entire databases when coming up with its answers. And while these models' general knowledge is great, being able to connect them to custom data and computations opens up many doors.

It's offered in Python or JavaScript (TypeScript) packages.Īs you may know, GPT models have been trained on data up until 2021, which can be a significant limitation. LangChain is an open source framework that allows AI developers to combine Large Language Models (LLMs) like GPT-4 with external data. Hopefully, I'll inspire one of you to come up with one of your own. In this article, I'm going to introduce you to LangChain and show you how it's being used in combination with OpenAI's API to create these game-changing tools. Instead, you can rely on AI to do the heavy lifting.īut how exactly are all these developers creating and using these tools? Well, many of them are using an open source framework called LangChain. Gone are the days where you need to scroll through a 50-page document just to find a simple answer. You may have even started using some of them.ĪI tools such as ChatPDF and CustomGPT AI have become very useful to people – and for good reason. You may have read about the large number of AI apps that have been released over the last couple of months.
