Noob question - in the quickstart tutorial there is this code
documents = SimpleDirectoryReader("data").load_data()
index = VectorStoreIndex.from_documents(documents)
query_engine = index.as_query_engine()
response = query_engine.query("What did the author do growing up?")How do I change the base url to point at a different server, not the openai server? I've combed the Internet and the site and can't find a mention anywhere.
