lab.
We measure things about AI systems and publish how we measured them.
two hands that don't line up A ragtime is two hands that don't line up: the left keeps steady time and the right is late on purpose. An AI system resembles that more than it would like — one layer that retrieves, another that generates, and the interesting part almost always happens in the gap between them. So much for the musical metaphor. From the first piece on, this is about milliseconds, gigabytes and vectors.
Every artefact is a page that opens and works. No sign-up, no build, no network, no dependencies: an HTML file you can download, look inside, fiddle with the knobs and break. They're numbered because numbering is free and looks good, not because you're meant to read them in order. Nobody reads them in order.
The code is MIT-licensed and the prose CC BY 4.0: take it, change it, publish it — just say where it came from. the terms, in the legal notice.
three house rules
[01]If there's a number, it was measured
And we say on what machine. An office laptop is a more honest data point than an H100 no client actually has.
[02]If a series is synthesised, the page says so
To your face, not in a 9-pixel footnote.
[03]Failure is data too
Several pieces exist because something came out backwards and telling you about it seemed more interesting than fixing it.
This is not a blog of opinions about AI. There are enough of those. It's a site where something concrete gets measured, the method is shown, and the script is left behind so anyone can repeat it and prove us wrong with numbers.
the structure
- Feterand
- the parent. Does applied AI for a living.
- Ragtime
- its lab. Measures, publishes, and builds the orchestrator.
- Artefacts
- the evidence. 17, and counting.
the byline
It's signed by Ando Hizemora, which is a heteronym — the letters of a real name, shuffled. The person exists, the researcher doesn't. It seemed more entertaining than writing “the team”.
