Professional-level training

Knowledge to help you learn.

Professional-level training in the systems reshaping how work gets done. Built for people who ship: engineers, analysts and students heading straight into the work.

Start learning See what you get

We teach how these systems actually behave, what they do well and where they fall over. The tools keep changing; the judgement is the part you keep.

What you get

Three things, and none of them a subscription to cleverness.

Everything here is pitched at working-professional level. The lessons assume you intend to build something real, and they keep going past the point where an introduction would stop.

A model can answer you. That is the least interesting thing it can do. These are the parts worth having.

Hands on

The systems themselves

Working access to the models, and a straight account of what each is good and bad at, including the days when the honest answer is that it will not help you. 13 series, 194 lessons, roughly 25 hours.

Built up

Lessons that stack

Each one builds on the last and is drawn rather than narrated at you. You should leave able to do the thing, not able to recognise its name.

Alongside

People a week ahead

Not a support desk. People who remember being stuck on exactly this and can tell you where it stopped being confusing.

A lesson looks like this

Why the model forgot what you told it

A model has no memory, only a window. When the conversation outgrows it, the oldest turns fall out, and your instruction from twenty minutes ago goes with them. Taught to professional depth, then you try it and watch it happen.

Solid is what the model can still see. The hatched part is what has already slipped out of the window.

How we work

Four things we hold to.

Show the working

An answer you cannot check is a rumour. Every claim comes with the thing it rests on, so you can disagree with it properly.

Confusion is information

If a lesson loses you, the lesson is wrong. We would rather hear where it broke than be told it was lovely.

The hard parts come first

The difficult explanations are the ones worth giving away, not the ones to hold back. If a topic is hard, that is the reason to cover it properly.

Pass it on

What you learn here you are expected to explain to someone else, in your own words. That is the test of whether it landed.
