Wouldn't that be the same if you used the OAI js library directly? Basically swapping the model parameter?

[jpulec]

It's not. The API is different, since GPT-4 is a chat based model, and davinci isn't. It's not a huge difference, but these little sort of things add up.

It is a very minor change (made the changes in minutes and didn't have to bring in a new framework for it).

[shepardrtc]

Agreed. It's a trivial change, certainly not a justification for using langchain.

I see, thought you were using GPT-3.5 and moved to GPT-4.
