I’ll save yall some time. If you are familiar with concatenating strings in python, langchain is a library which does just that, only a little less cleanly. Hope this helps!

That's a bit cynical. It does many other thing as well. For example, it exposes simple re-usable modules, also known as "functions" in Python. Sometimes it also uses Python "lists" by wrapping them into... classes.

Class incomprehension is the defining feature of LangChain!

I noticed there is a lot of negativity against langchain on HN. Is it because it's very popular? For example deeplearning.ai has courses on LangChain. You think someone like Andrew Ng will stand behind an overhyped tech?

Absolutely Andrew NG would make questionable decisions imo. I was shocked to see him teach his classes with Matlab year over year when everyone and their mother was proficient in python.

It inflates its promises and then grossly under delivers.

It’s only value is abstractions and it gets these wrong. That said I’m not against it and I hope it improves.

Do you have any thoughts on what the right abstractions are? Asking for a friend.

It's worth cribbing ideas from. But most of what it does is simple enough and wrapped in enough abstraction that it's often easier to just take those ideas and apply them to your own code vs. using LangChain itself.

Oh weird, I thought its basic concept was embezzling VC funding?
