LangChain for LLM Application Development

Beginner 1 hours English Course CertificateFREE
Our recommendation
A fast, one-hour guided project moving through LangChain's core building blocks — calling LLMs with prompts and parsing responses, adding memory, and chaining calls. Concise and hands-on, ideal for developers who want a quick, practical first look at LangChain. Note it uses model APIs (billed separately), and the same DeepLearning.AI short course is also available free on their site.

Good for: A quick, hands-on first look at LangChain's core building blocks.

Less suitable if: You cannot code Python or want an in-depth course.
