Evaluation

Two external benchmarks nobody on the team authored: the closest prior work's own question set and real openFDA malfunction reports, both scored by two independent judges against named baselines. Also negative controls, citation integrity, the offline comparison and cost. Everything on this page is read from eval/results/latest.json in the repository.

Citations that resolve to the manual

Sieve points at numbered manual sentences and code copies the exact text, so every citation lands on real text.

Negative controls

Rules engine and registry only. No model is involved, so these numbers hold offline.

Benchmark A: INGENZI held-out (competitor's own dataset)

Three systems answer the same 300 questions from the closest prior work's published dataset (CC BY-NC 4.0). A blind Nemotron 3 Super judge grades each against the reference. Sieve is the only system whose answers carry a verified citation.

Benchmark B v2: openFDA malfunction reports (pre-registered)

Real FDA reports of oxygen concentrators that smoked, burned or caught fire, selected and scored by rules committed before the run. In every one, Sieve took the machine out of service before showing a single repair step.
