Lately LangChain[1] and GPT-Index[2] are very popular libraries for this sort of thing.

This is the vid I started out with https://www.youtube.com/watch?v=rBEHPxVHb5c

Also that channel seems to be great. They focus only on LangChain and GPT-Index lately and post videos every few days https://www.youtube.com/@echohive

Both have Discord servers as well.

Additionally there's also this website for GPT-Index ( https://llamahub.ai/ ) where people add different "connectors", like loading up your .md files, .docx files, your notion, your slack, etc.

They say they use LangChain, so it's going to be structurally similar to this MVP side-project: https://thundergolfer.com/infinite-ama.

That's a chat-bot backed by LangChain and OpenAI, which can answer some questions from my knowledge base.

It's WIP, I want to add my HN comments into the mix, but the code is here: https://github.com/thundergolfer/modal-fun/tree/main/infinit...

we're using LangChain underneath and we also doing RnD on fine-tuning to see and compare performance of different approaches. Can you tell me what file format is your knowledge-base? is it PDF or MS Docs or any other?
