Build amazing business applications using LangChain and LLMs.

The LangChain library radically simplifies the process of building production-quality AI applications. It provides a set of intuitive abstractions for the core features of an LLM-based application, along with tools to help you orchestrate those features into a functioning system. AI Apps with LangChain provides clear diagrams and abundant code samples that teach you exactly how to build useful LangChain-based AI apps.

In AI Apps with LangChain you’ll learn vital skills of developing applications with LLMs, including:

• Design patterns for LLM applications, including Retrieval Augmented Generation (RAG)
• Using LangChain to implement LLM solutions
• Picking the right LLMs for your projects
• Deploying an LLM anywhere—from your laptop to the cloud
• Fine tuning an existing LLM for your exact needs

Building applications based on LLMs isn’t limited to huge tech companies with unlimited resources. AI Apps with LangChain teaches you to use the user-friendly LangChain library to create your own research assistants, information enterprise chatbots, and more. There’s no long technical deep dives or academic jargon—the book’s pragmatic approach gives you just enough theory to start building working apps.
