TL;DR: Microsoft’s AI for Beginners is a free, open-source 24-lesson curriculum on GitHub that teaches real AI fundamentals — from old-school symbolic AI through neural networks, computer vision, NLP, and reinforcement learning. Each lesson has quizzes, labs, and assignments, and it uses TensorFlow and PyTorch. There is no certificate and no instructor, but for self-motivated learners it’s one of the best free AI courses in existence.
What is Microsoft’s AI for Beginners?
It’s a 12-week, 24-lesson curriculum published by Microsoft on GitHub (github.com/microsoft/AI-For-Beginners), with an accompanying site at microsoft.github.io/AI-For-Beginners. Unlike most “learn AI” courses that stop at prompt engineering, this one goes under the hood: it covers symbolic AI and knowledge representation, neural networks and deep learning, computer vision, natural language processing, generative adversarial networks, and reinforcement learning.
Each lesson follows the same structure: a written lesson, a quiz to check understanding, and hands-on labs and assignments with code — much of it in Jupyter notebooks using TensorFlow and PyTorch. The curriculum is also translated into multiple languages by community contributors.
Pricing (verified October 2026)
| Item | Price | Notes |
|---|---|---|
| All 24 lessons, quizzes, labs | $0 | Fully free, open-source (MIT license) |
| Optional: cloud/API costs | $0–minimal | Most exercises run free on your own machine; a few optional exercises may need an AI API |
| Certificate | Not offered | There is no credential at the end — this is pure learning |
There is genuinely nothing to buy. The only “cost” is your time and a computer that can run Python.
What’s good
- It teaches how AI works, not just how to use it. Most beginner AI courses in 2026 are prompting courses. This one teaches backpropagation, embeddings, transformers, and reinforcement learning — the actual machinery.
- Structured like a real course. Lessons build on each other in a deliberate order, with quizzes and assignments at each step. It doesn’t have the random-walk feel of a YouTube playlist.
- Hands-on with real frameworks. You write code in TensorFlow and PyTorch, the two frameworks actual AI jobs use. That’s rarer in free courses than it should be.
- Surprisingly broad. Symbolic AI, genetic algorithms, and multi-agent systems get covered alongside deep learning — topics most modern courses skip entirely.
- Multi-language support. Community translations make the material accessible well beyond English speakers.
What’s not so good
- No certificate, no credential. You finish smarter, but with nothing to show a hiring manager. Pair it with a portfolio project or a paid certificate if resume value matters.
- No instructor or support. When you’re stuck on a lab at 11pm, it’s you and GitHub issues. Self-discipline is mandatory.
- Some content is aging. The deep learning fundamentals hold up, but the cutting edge moves fast — a few lessons won’t reflect 2026’s state of the art. (Microsoft’s separate 21-lesson Generative AI for Beginners repo covers the modern LLM stack if that’s your focus.)
- Assumes basic Python. True programming beginners will struggle. Learn Python basics first.
Who it’s best for
Curious, self-motivated learners with basic Python who want to genuinely understand AI — students, career switchers doing prep before a paid program, and developers who use AI tools daily but want to know what’s happening underneath. Not ideal if you need a certificate for your resume or you learn best with live instruction.
The verdict
Microsoft’s AI for Beginners is the rare free course that’s both broad and deep. It won’t give you a credential, but it will give you something more durable: actual understanding of how neural networks, vision models, and language models work. For $0 and 12 weeks of evenings, that’s an outstanding deal — and the perfect free on-ramp before spending money on a paid certificate like IBM’s or an AWS exam.
FAQ
Is Microsoft’s AI for Beginners really free?
Yes — all lessons, quizzes, labs, and assignments are free and open source. No account, payment, or sign-up required.
Do I get a certificate from Microsoft’s AI for Beginners?
No. The curriculum doesn’t include any certificate. It’s designed for learning, not credentialing.
How is this different from Microsoft’s Generative AI for Beginners?
AI for Beginners (24 lessons) teaches AI fundamentals — neural networks, vision, NLP, reinforcement learning. Generative AI for Beginners (21 lessons) focuses on the modern LLM stack: prompting, RAG, agents, and fine-tuning. Take both if you want the full picture.
Do I need to know Python?
Basic Python is expected. The labs use Jupyter notebooks with TensorFlow and PyTorch, so complete programming beginners should start elsewhere.
