Transformer Primitives – A visual explainer you can send to anyone

I have had a few conversations in the past year with non-technical folks (traditional finance types, consultants) who asked for a simple explainer on how GPTs work. These people generally have the horsepower to grasp new concepts quickly but don't necessarily have the math background to dig in super deeply and want a stronger framework than "they predict words". I had generally been pointing them to Karpathy, Illustrated Transformer, and other youtube content but I figured something more hands on without the math requirement might be better at explaining questions like "why matrix…

What it does

In the maker’s words, at launch

I have had a few conversations in the past year with non-technical folks (traditional finance types, consultants) who asked for a simple explainer on how GPTs work. These people generally have the horsepower to grasp new concepts quickly but don't necessarily have the math background to dig in super deeply and want a stronger framework than "they predict words". I had generally been pointing them to Karpathy, Illustrated Transformer, and other youtube content but I figured something more hands on without the math requirement might be better at explaining questions like "why matrix multiplication?". I built this as a simple 60-70 minute interactive course with some demos I could send along to them. I've found it effective as the initial foray into understanding jargon and concepts before they graduate to Karpathy et al. It's free, no signup required. I would love feedback on where it might lose a non-technical reader, and where someone who does this for a living thinks I have simplified past the point of being correct. understandgpt.xyz

    An interactive transformer “debugger” been working on in my free time2023 · github.com · ▲8

    My focus has been shifting towards the ML alignment space recently, and in particular the ability to translate large transformer models into human understandable circuits and algorithms. This problem potentially isn't solvable, but it is one that some groups have had success with after large amounts of effort. In attempting to address this issue, I've been developing Transpector. A tool scaling up and reducing the barrier to entry of techniques that these teams have been showing success with. Techniques aiming to understand the internal mechanics of the model. Currently this tool is focused…

    Learning Project: building an imperative language2020 · ▲36

    Hi! I am doing a learning project, attempting to build an imperative language (and interpreter). The end product will be useless for others, I just want to learn and better understand how to build imperative languages. :) If someone else shares this interest and want to give some good hints on good resources I would be grateful. Currently I am looking at an awesome text by Bob Nystrom. All suggestions and tips on resources are most welcome. I am very much a beginner in this, but I find this topic very fascinating. Mail me or post links here! Cheers! You can try a beta version Online at…

    Crash course in Qt for C++ developers – a blog post series2018 · ▲27

    Hi guys, Two days ago I published the fourth post in the series and thought it would now be a good time to look for additional feedback here on Hacker News. The aim of the series (as mentioned in the first post) is to inspire more people to start using Qt. My ambition is to answer the following questions "what is the gist of Qt?"; "what is the 20% that you need to know to develop 80% of the application?"; "what are the perhaps unknown unknowns?". In other words, I'm just covering basics: enough to understand the concepts and where to find additional information should you need it. Do you…

    An interactive AI tutorial I wrote for my 11-year-oldMay 2026 · learnai.robennals.org · ▲5

    I've created an interactive tutorial that teaches how AI models work. I set myself the goal of making it approachable enough that my 11 year old son Isaac can fully understand it. The tutorial aims to be easily understood by anyone who understands basic math, and yet give them a deep intuitive sense of not just how AI works but why it works the way it does. It does this using a series of interactive playgrounds that let the reader play with each idea. Currently there are 9 chapters, starting from scratch and ending with transformers. I'm planning to keep adding more chapters until the…

    Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
