Free to practise. $19 for a year of the full courses.
Every problem, hint and explanation is free, and so are the Patterns and Interview Prep lessons and the first chapter of Machine Learning and of AI Engineering. A year opens the rest of those two courses and adds the recorded voice: the Solution tab read aloud, and a narrated walkthrough video of every problem.
A year
$19 for a year, in US dollars (USD), paid once. It is not a subscription: nothing renews, and you are never charged again. The price is final: nothing is added at checkout. Your bank may convert it to your own currency.
What a year includes
- Machine Learning after its free first chapter, Math foundations: 30 lessons in 6 chapters, from neural networks and PyTorch to training, NLP, attention and a small GPT, and the workshop's tiny GPT to download and train.
- AI Engineering after its free first chapter, Model foundations: 8 lessons in 3 chapters, on retrieval and context, safe tool use, evaluation and cost, and the roadmap's 4 project milestones.
- Read aloud: the explanation on each problem's Solution tab, read in a recorded voice, starting from any heading.
- Animated walkthroughs: a narrated video of the solution for all 150 problems, with the drawing of the data and the code moving together and captions you can switch on.
- A walkthrough video for each of the 42 lessons on the Patterns page.
- A shorter walkthrough video for each of the 12 AI Engineering lessons.
Free for everyone
- All 150 problems in JavaScript, TypeScript or Python, with tests that run in your browser.
- Hints, explanations and reference solutions.
- The Patterns and Interview Prep lessons.
- The first chapter of Machine Learning, Math foundations, and of AI Engineering, Model foundations.

Buying a year
Create an account and confirm your email, then press Buy a year in the Account dialog. You pay on the secure page of Flitt, our payment provider, with a Visa or Mastercard card, Apple Pay or Google Pay. Access starts as soon as the payment goes through, and an email confirms it with the day it ends.
When the year is over, those lessons, the recordings and the videos lock again until you buy another; your progress stays. A year bought while one is running starts when that one ends. Payments are not refunded: see the refund policy.
