about

uutaiset keeps two ledgers.

ai/ is a timeline of how machine learning got from the perceptron to today's reasoning models. It mixes three kinds of entry. A milestone is a thing that happened: a model, a system, a result. A technique is an idea that moved the ceiling: backpropagation, attention, RLHF, chain-of-thought, verifiable-reward RL. A benchmark is a yardstick, and how fast it broke. Each technique lists what it relied on and what it later enabled, so you can walk the dependency graph in either direction, including across into the mathematics.

math/ is a timeline of mathematics found or proved with machines. It starts with the pre-AI computer proofs so the lineage is honest, then tracks the learned systems: intuition-guiding models, RL provers, evolutionary code search, and large language models. Each entry says what the object is, what was actually shown, how much of it was the machine, and who checked it. Rumours get entries too, labelled as such, because they are part of the record.

Entries are plain markdown in content/, built by a short Bun script with no framework and one dependency, a markdown parser. The filter checkboxes are the only JavaScript. Source is a private repository; the site deploys from it.

Dates are ISO, preprints are dated by first arXiv version, and anything that was only a press release or a post is marked as such. Corrections welcome.
