Integrating LLM APIs with LangChain

In this chapter, we will build upon the foundational knowledge from Chapter 1 to gain a more in-depth, practical understanding of working with LangChain and LLM APIs to build robust and scalable generative AI applications. While Chapter 1 provided a broad overview of LangChain and LLMs, this chapter will go deeper into the practical aspects of integrating LLM APIs with LangChain, including hands-on exercises and detailed technical setup instructions.
