I can understand if they identified that building with LangChain means more Pinecone usage, and a barrier to building with Langchain is its documentation and ease of getting started, but if the now well funded project isn’t producing this itself (and in my own experience the Typescript library at least doesn’t feel like it’s hitting the nail on the head and I ended up reading source code) then I think that’s a sign we’re still searching for the best way to build complex things here
