Inhaltsangabe

If you're looking to build production-ready AI applications that can reason and retrieve external data for context-awareness, you'll need to master--;a popular development framework and platform for building, running, and managing agentic applications. LangChain is used by several leading companies, including Zapier, Replit, Databricks, and many more. This guide is an indispensable resource for developers who understand Python or JavaScript but are beginners eager to harness the power of AI.

Authors Mayo Oshin and Nuno Campos demystify the use of LangChain through practical insights and in-depth tutorials. Starting with basic concepts, this book shows you step-by-step how to build a production-ready AI agent that uses your data.

• Develop and deploy AI applications that interact intelligently and contextually with users
• Make use of the powerful agent architecture with LangGraph
• Integrate and manage third-party APIs and tools to extend the functionality of your AI applications
• Monitor, test, and evaluate your AI applications to improve performance
• Understand the foundations of LLM app development and how they can be used with LangChain
