When a Judgment Layer's Self-Reported Fields Lie

Perry Link's Zenodo preprint compares three judgment layers - a local Laya judge, TypeSafe Jev and DeepSeek-V4.1-Flash - on the same 120-checkpoint task, reporting that cost is not the binding constraint, that p50 latency spans about 25-32x, and that the judges' self-reported fields fail in clustered ways.

Highlights

  • Measured per-call costs: Jev $0.0000146 to $0.0002406 over 8 direct-route points; DeepSeek-V4.1-Flash $0.0000326 to $0.00009645; Laya near zero marginal cost.
  • p50 latency spans 25-32x: Laya 37.4 ms, the frontier model 671 ms, Jev 1.19 s in one n=20 run (pooled median 1.07 s).
  • Main finding: self-reported fields fail; when a candidate value never appears in the input, the judge still averages P(true) = 0.5643 (n=220).
  • Six phenomena were reproduced on real calls, including a truncation flag wrong in both directions and two verdict words that are unreachable under real inputs.
  • Calibration correction included: REL 0.0556 / RES 0.0397 / UNC 0.2400 and AUC 0.7136; resolution exists, but Brier 0.2571 is worse than a constant's 0.2400.

Watch out

Copy reviewed against the Zenodo abstract and visible page text on 2026-10-15; the fetched page was truncated mid-abstract, so the third and fourth claims, the appendices and the artifacts were not readable. It is a self-published v2 preprint that flags its own corrections and re-measurements, and every cost, latency and calibration figure is the author's measurement on this single harness.
