Community project / Evaluations and independent research

jev-fanout-bench

Billing study comparing batched and one-question-per-call Jev requests through OpenRouter's TypeSafe-compatible endpoint, with synthetic English tickets sent to the provider, raw responses and charge records, and repeated requests to measure answer stability; the tickets are unlabelled, and separate-call latency was measured serially.

  jev-measured

  Reproducible OpenRouter measurements of Jev's response shapes, cost, and latency across eight use cases, plus a small head-to-head on 27 author-written support tickets; the author publishes raw data and corrections to earlier comparison errors.

  jev-ood-calibration

  Independent Jev calibration study with raw Gateway responses from three public benchmarks and 900 rule-generated support tickets; probabilities were near calibrated on the public sets but overconfident on an unseen priority rule, while the Boolean question showed a different error direction. The synthetic task is one family and the Gateway did not expose a fixed model version.

  jev-orderby-bench

  Independent measurement of whether ORDER BY over a Jev probability is defensible, with a pre-registered gate on pairwise inversion, Score ordinality against a graded target, calibration, and negation and paraphrase invariants; jev-1.13.0 passes on 20 Newsgroups topic membership and fails four of six conditions on Amazon ESCI human-graded product relevance, the DuckDB integrations' request shapes are shown to change the numbers (a 40-row batched state fails the ranking gate that one row per request passes), and two-decimal output leaves 53 of 360 rows tied at the top so LIMIT k cuts inside a tie; one seed and 30 ESCI queries, aggregates committed, corpus and cached responses regenerated locally for about a cent.
