ChatOpenAI + SerpAPI + History

[progrmoiz]

I'm trying to figure out how to merge ChatGPT with Bing Search and was looking at this example. It talks about Buffer Memory as history, but what I want is to be able to provide my own history. How can I give multiple messages as context for ChatOpenAI instead of BufferMemory and use SerpAPI as a tool?

I also found this guide!
