Hey clever people, 

Here is your no-fluff way of learning to build AI agents for free. 

If you want to learn how AI agents work, not just the theory, but the real frameworks and tools being used, this free course from Hugging Face is a no-brainer. (Seriously, it's such a game-changer that we almost didn't share it because we're selfish.)

What you'll learn:

  • Core concepts like thoughts, actions, observations, and tools

  • How to use top libraries: smolagents, LangGraph, and LlamaIndex (we didn't make up these names)

  • How to fine-tune LLMs for tool use and function calling

  • Real-world use cases: build an agent to solve an actual problem

  • How to evaluate agents, track memory, and even play Pokémon with AI (because, in the end, everything leads back to Pokémon)

Format:

  • Structured weekly modules (3 to 4 hours/week)

  • Bonus units on games, observability, and fine-tuning

  • Certification track available. You can submit assignments, pass challenges, and earn official Hugging Face credentials

Whether you're a beginner or already building with Langchain, this course will sharpen your thinking and improve how you architect agent-based systems. (Meaning: you'll sound way smarter in meetings.)

Final Deadline for Certification: July 1, 2025

This is a no-BS course that you should sign up for.
