Over the past few weeks, Mark and Allen have been playing with LangChain and OpenAI, exploring where #ConversationalAI and #VoiceFirst design intersects, and we recorded some of our experiments. In this early one, we take a look at how LangChain with a memory chain can work and keep track of what's going on in the conversation. All in just a few lines of code. More significantly, we discuss the role that LangChain can play in putting together AI and other API components to create voice, web, and app-based agents that include AI as part of the NLU or response elements.
