AI Application Development with LangChain

As artificial intelligence evolves, the ability to connect large language models to your own data and external tools has become a critical skill for modern developers. This course provides a clear path to understanding how to bridge the gap between static AI models and dynamic, real-world applications. You will progress from foundational concepts to building sophisticated systems that can remember past interactions, browse the web, and analyze private documents. By the end of this course, you will be able to design and implement context-aware AI agents that solve specific, complex problems. * Understand foundational AI concepts and the architecture of the LangChain framework. * Implement Retrieval-Augmented Generation (RAG) to allow models to interact with external data. * Apply LangChain Expression Language (LCEL) to create flexible and efficient AI workflows. * Configure vector databases to store and retrieve information with high precision. * Practice prompt engineering patterns to guide model behavior effectively. * Integrate third-party tools and APIs to expand the functional range of your AI applications. The course begins with essential terminology and the basic building blocks of LangChain before moving into practical implementation strategies for memory, data retrieval, and agent-based reasoning. You will learn through written explanations and code-based exercises designed to reinforce modern development patterns. This course is designed for beginners and aspiring AI developers who have a basic understanding of Python but are new to LangChain and large language model orchestration.
