The runs behind the figures

Our product pages carry numbers. The runs behind them are published here, with the day each was run and what came back.

Quorum × Jev: half the calls, twice the speed, citations that cannot be invented

Three language model passes replaced by one typed call, and what that was worth in speed and in citations that cannot be invented. Includes why our grading step is the wrong job for a decision-only model, and which job is the right one.

Overclaim18 Sept 2026

A second reader that catches Attest overreaching, on 190 claims

Every verdict checked by a model that writes no text and only answers typed questions, asked whether the conclusion is more generous than the evidence. Five runs against one of the deployed product, with each run published.

Claim verification18 Sept 2026

Attest on 190 hand-labelled claims

A labelled set of claims: multi-hop reasoning, arithmetic, distractors, scope traps, conflicting sources. The run also found a defect, published on the same page.

Study: a fixed set, a method written down before the run, every per-item result published. Where the set was also in use while the product was being developed, the study discloses this. Saved call: one real answer, replayed on the page it illustrates.

Dates are the day the work ran, not the day the page shipped. A repeated run replaces its figures and its date together.

The savings calculators are not in this list. They are assumptions about how long a job takes by hand, and they say so where they sit.

How we publish

01

Freeze

The set is written to a file with a timestamp before anything is called. The runner reads only that file.

02

Run

Each provider is called once on each item. The answer is saved verbatim, next to its source. No retries.

03

Score

The saved answers are measured against that source, or against a label written beforehand.

Where the measure allows it, no model marks our work: extraction is scored against each page's own HTML, claim verification against labels written before the run. Where a study needs a model to answer or grade, it is blind to which side it is reading, audited, and the measured agreement is published.

Runs that go badly are published as well. Attest's own measurement turned up a robustness defect, and it sits beside the accuracy figure on the Attest page.

They are also how we decide what to fix. What a run turns up in our own service becomes work, and the next run is where you see whether the work landed.

Where only one column of a comparison has been run again, both dates are printed. In the extraction comparison, Kerf's column was re-run after changes to how it reads pages; TinyFish's answers are the ones saved on the day, and every page is still scored against the HTML saved then.

The extraction run recorded three failures which turned out to be our own edge reporting a site's refusal as our error. They stay in the run as they happened, with the re-check under them rather than in place of them: a run is a record of a day, not a claim about today.

Ask us to measure something

If a figure you need is missing, or you would rather see the comparison run against your own pages than against ours, say so. We will run it and publish what comes back.

Attest's labelled set is one author's work on one distribution, and hosted inference is not bit-reproducible, so small differences between runs are noise. Both caveats are stated on the Attest page. If your documents look nothing like that set, the useful number is one measured on yours.

Figures are read from the run that produced them rather than typed onto a page. Naming another product is not a claim about anything except what it returned on the addresses we tested, on the day we tested them.
