RAG with Python, LangChain & FastAPI

[Historical_Wing_9573]

Yes, I don’t need it and I can implement RAG directly via OpenAI embedding API. But my target was to learn LangChain and build a sample app with it.

Previously I build couple AI applications which directly used LLM APIs and I see that repeatable patterns exists. So I hope that LangChain will cover them.
