Yes. All 3 tracks, 24 modules and 24 challenges, permanently, with no account required to read them. We do not intend to put any of it behind a login later.
Not the teaching. Pro is the part after learning: a bank of the questions really being asked, an assistant that tailors and files applications for your approval, a tracker and calendar built for ML loops, and a community of people inside the companies you are aiming at.
No, and the site says so on every feature page. The curriculum ships first and the Pro tools follow. If buying something that has not shipped is not for you — which is reasonable — the free material is there regardless.
No. It is one payment covering 5 years of access. There is no renewal, no monthly tier, no annual plan and nothing to cancel. That works out to about $1,980 a year over the term.
No, but you do need the maths. Track 01 builds linear algebra, calculus, probability and statistics from the start, attached to the models each idea shows up in. Start there if the notation in a paper is what stops you reading it.
Around 203 hours of material. At ten hours a week that is roughly a year; people already working in the field skip the first tracks and go considerably faster. The checkpoints are what tell you whether skipping was a mistake.
Never. It drafts the application and fills in the form on the company’s own site, then stops. Every single application waits for your approval, and there is no approve-all button.
Not yet. The curriculum ends at the transformer, which is the architecture every LLM is built from — so it takes you to the door rather than through it. There was an LLM track here and it was removed, because it was written without a source and we could not stand behind it. It comes back when there is something real to teach from.


Every course is free to learn. Start with one that is open, at the level that is honestly yours.
