AI, But Simple Issue #96

Andrej Karpathy is a well-renowned computer scientist and leader in today’s Artificial Intelligence public forum. Some of his best work stems from the craft that the community deems "minimalist engineering.”
On February 12th, he posted on his GitHub a blog called MicroGPT, where he showcases his latest creation: a 200-line project containing the very backbone of frontier model chatbots like ChatGPT.
Today, we’ll visually break down the project, piece by piece, unraveling the engineering marvel. We’ll look at the complete architecture, from the dataset to the last layer output, and understand deeply how each component contributes to the full mechanism.
MicroGPT is not meant to replace the frontier models, by no means. In fact, the model simply outputs predictions for how to complete names, which its original database is full of.
However, it represents something bolder. Even with how sophisticated modern LLMs become, the core of what makes them work can be simple.
In Karpathy’s breakdown, these principles are elegantly on full display.
