LangGraph Complete Course for Beginners – Complex AI Agents with Python
freeCodeCamp.org. A long, code-along build through LangGraph's state graphs, nodes, edges, conditional routing, checkpoints, and tool use. By the end you have enough feel for the typed-state, "every transition is explicit" model that the article's comparison to CrewAI and to direct-API code stops being abstract.

Coursera · Vanderbilt UniversityChatGPT: Excel at Personal Automation with GPTs, AI & Zapier
The clearest path from "I use ChatGPT in a tab" to "my AI handles my inbox while I sleep." Three-course specialization built around Zapier — no Python required. By the end you'll have agents that summarise emails, update spreadsheets, and trigger workflows when conditions are met.
Hugging FaceAI Agents Course
The clearest open-source treatment of agentic systems available. Anchored in the three frameworks engineers actually evaluate (smolagents, LlamaIndex, LangGraph) rather than one vendor's stack. Concludes with a benchmark assignment and public leaderboard — accountability your team can verify.
