LangChain courses can help you learn how to build applications that connect large language models with external data, tools, and workflows. You can build skills in prompt chaining, retrieval methods, agent design, and structuring multi-step tasks. Many courses introduce tools such as Python libraries, vector databases, and APIs that support creating, testing, and refining LangChain-powered AI applications.
