Function Calling in Conversational Retrieval QA chain.

Is it possible to use Open AI Function Calling in the Conversational Retrieval QA chain? I didn't found anything related to it in the doc.

Haven't tried it yet, but this caught my eye: https://js.langchain.com/docs/modules/agents/tools/agents_with_vectorstores

There is ChainTool class which seems make tool out of a chain. So if you can have a tool, there is no reason to not to use it in an agent. Like I said, I haven't tried, it's just an idea.

Btw, let me know if this works if you try :)
