A plain guide to the site, for readers with no background in AI.
In short
This site holds the work of Zain Dana Harper, published under the working name Zentropy Labs. The work keeps returning to one question: when an AI system, or the company behind it, makes a claim, how can someone else check it? Pick the door below that fits what you came for.
Four ways in
If you came to read
Who Knew First traces nine AI agent incidents from 2026 and asks how long the public waited to hear about each one. It opens with a short op-ed and keeps the full record underneath.
If you follow AI policy
The Frontier Safety briefing is a dated record of safety news. Each edition ties every claim to its source and says what that source cannot show.
If you want to try the tools
Flywheel runs a task with any AI model and hands the result to a checker that anyone can rerun offline. Install it with one command.
If you want to hire or work together
The work page lists resumes, the full CV and ways to get in touch.
What re-derivable means, in one example
Say a company reports that its model passed 120 of 150 coding tasks. A re-derivable report comes with the tasks, the model version, the test that graded each answer and a record of every result. You run the same test on your own computer. If you also get 120, the verdict is match. If you get a different number, the verdict is drift, and the record shows the exact task where the results part ways. If the report leaves out something you need, such as the tasks themselves, the verdict is unverifiable, and the missing piece is named.
How to read the charts and diagrams
Each chart opens with one sentence that says what it shows, then a short line on how to read it. Labels sit on the chart itself, in plain words. Under each chart, a section called How we know holds the sources, sample sizes, dates and limits. Open it when you want to check the work.
How AI assistance is labeled
Much of this site was written with AI assistance, and the pages say so where it applies. The prose is checked with Articulate, a writing checker built here, before it goes up. A clean check means the writing avoids known patterns of filler, hedging and stock phrasing. A clean check says nothing about whether a claim is true. The sources and the How we know sections carry that weight.
What this site does not claim
The tools are built to serve people who evaluate AI systems. No pilot, contract or engagement with any AI lab is in place. Where a page reports a result, it also says what the result cannot show.
Words you will meet
A short glossary explains the terms this site cannot avoid, such as receipt, verdict and witness.
