With chat agents as the llm (e.gChatOpenAI ), if using refine method , would it keep an ongoing chat history on node 1 - N? I have seen turbo 3.5 do pretty bad as it refines each node but I had a creeping suspicion the chat history was just adding accumulating too much context as the refine process went on. At least for some of the azure models I am limited to using the ChatOpenAI model . And response mode was set to “refine” fyi
