Generative AI with LangChain: Build large language model (LLM) apps with Python, ChatGPT and other models

ABSTRACT

LangChain has emerged as the premier orchestration framework for connecting large language models to external tools and databases. This practical guide walks developers through the process of building capable AI applications, from basic chatbots to complex autonomous agents. Auffarth details how to construct robust memory chains, implement dynamic routing, and integrate vector databases for sophisticated RAG systems. It is an ideal starting point for software engineers looking to rapidly prototype and deploy generative features.
