It's a really exciting time in AI, and there's lots of advancements happening. In this course, we covered two of them, OpenAI Function Calling and Langchain Expression Lnguage. We then showed how you could use those to do structured data extraction, and then also tool usage and tool selection. And we put that all together by building a conversational agent at the end. With all these learnings under your belt, the only thing left to do is go out into the real world and apply them to your use cases.
