LangChain Fundamentals Training in Thimphu, Bhutan

This course introduces participants to LangChain, a leading framework for developing applications powered by Large Language Models (LLMs). It covers the core building blocks, integrations, and use cases of LangChain, enabling learners to build conversational AI, intelligent agents, and workflow automation solutions. The program blends concepts, hands-on labs, and project-based learning.
