LangChain for LLM Application Development
by DeepLearning.AI + LangChain
LangChain is the framework used by engineering teams worldwide to build real AI applications on top of models like ChatGPT and Claude. This free course from DeepLearning.AI teaches you the core components — chains, agents, memory, and document retrieval — so you can build AI tools that do more than answer a single question. It is one of the most in-demand technical skills in AI engineering right now, and at 2 hours it is fast to complete.
What you will learn
- How to use LangChain to build AI applications that go beyond single prompts
- Memory: how to give an AI app the ability to remember previous parts of a conversation
- Document retrieval: how to build an AI that answers questions based on your own documents
- Agents: how to give AI the ability to use tools and take multi-step actions
- How to chain together multiple AI steps into a reliable automated workflow
Who is this for
- Developers who want to build real AI products, not just chat with ChatGPT
- Engineers transitioning into AI engineering or adding AI to existing applications
- Technical product managers who want to understand how AI apps are actually built
- People who completed 'Building Systems with ChatGPT' and want to go further
