FastAPI example with LangServe (old chat-langchain implementation): https://github.com/langchain-ai/chat-langchain/blob/langserv...
Or just use regular fastapi endpoints instead of langserve.add_routes with a fastapi server: https://fastapi.tiangolo.com/
OOC which openai model were you using? Would recommend trying 4o as well as Anthropic claude 3.5 sonnet if ya haven't played around with those yet
I was using gpt-3.5-turbo-0125. It was before the recent pricing change.
But I have a bunch of updates to make to the json schema, so will re-run everything with gpt-4o-mini.
Sonnet seems a lot more expensive, but I'll 'upgrade' if the schema changes don't get sufficiently good results.
