The Website for This Book

Translated from the German original.

This book explains fundamental mechanisms that stay relevant for the long run. How an AI learns from text, how it computes, why a convincing answer can still be wrong. That doesn't change every year.

Other things change constantly. Which model is currently the strongest, what a provider costs, which tools are worth it. Details like that don't belong in a printed book, because they are already outdated by the time it appears. That's what the website is for.

You'll find it at ai2718.com.

That's where everything lives that belongs to the book but isn't well served by a fixed binding. The glossary with all the technical terms that appear here. A search across the entire text, for when you want to find a passage again. The sources, for looking things up and reading further. Companion material for individual chapters. And a page with corrections: if a passage in the book turns out to be wrong or misleading, the correction is published there.

There is also a newsletter. In it, I write regularly about what is moving in the field. Which models have arrived, which tools are actually useful, what is happening in the market. That is the part a book cannot do. The book gives you the understanding to put new things in context. The newsletter brings you the new things.

If you want to stay on the ball after reading, sign up. It costs nothing, and you can leave again with one click.

And if you spot a mistake or a passage stays unclear, let me know. There is a way to do that on the website. If possible, mention which passage you mean. Then I can retrace it and correct it in the next edition.
