AI Agents in LangGraph
For: Engineers who have used the OpenAI API but never built an agent loop
Side-by-side comparison on level, duration, pricing, instructor, tier. Editor verdict on which course wins for which buyer.
The shortest path from 'I read about agents' to 'I built one that works.' Harrison Chase walks through LangGraph's state machine model end-to-end — agentic loop, tool use, persistent state, human-in-the-loop. Free, ~90 minutes, and the only short course we recommend ahead of a longer specialization. Limitation: it assumes Python comfort and skips over LLM fundamentals. Pair it with the LLM Fundamentals course below if you're new to the field.
The official deeper-dive into LangGraph from LangChain Academy. Where the DeepLearning.AI short covers basics in 90 minutes, this one goes 6-8 hours into state, persistence, human-in-the-loop, streaming, and the LangGraph Cloud deployment story. Free, taught by LangChain engineering. The canonical follow-up after the DL.AI short course if you're committing to LangGraph for production.
