My favorite Udemy courses to learn LangChain, RAG and AI Agents Automation
Hello guys, If you’re someone who’s excited about building cutting-edge Generative AI applications in 2025, there’s no better time to learn LangChain.
It has quickly become one of the most in-demand frameworks for building LLM-powered apps using OpenAI, Ollama, Mistral, Claude, and even custom models.
LangChain makes it easy to combine language models, tools, memory, vector databases, and agents to build robust GenAI applications — from chatbots to AI assistants, from RAG systems to workflow automations.
Earlier, I have shared best ChatGPT courses, best Data Science courses and best Machine Learning courses as well as 10 Must Read AI And LLM Engineering Books and in this article, I am going to share best Udemy courses to learn LangChain, RAG and AI Automation.
Being an aspiring AI developer myself and having enrolled in several top-rated courses on Udemy, I’ve handpicked the 6 best LangChain courses to help you upskill and stay ahead in this fast-moving field.
By the way, if you are new to AI world then I highly recommend you to start with The AI Engineer Course 2025: Complete AI Engineer Bootcamp, one of the most comprehensive resource to become an AI Engineer in 2025.
Let’s dive in!
