This is a comparison of apples to oranges. Langchain has an order of magnitude of examples, of integrations and features and also rewrote its whole architecture to try to make the chaining more understandable. I don't see enough documentation in this pipeline to understand how to migrate my app to this. I also realize it would take me at least a week even migrate my own app to Langchain's rewrite.
Langchain is used because it was a first mover and that's the same reason it's achilles heel and not for speed at all.
