MedPhysBench v1.0 - Calculation: leaderboard

Medical physics calculations and detecting planted mistakes under deterministic tolerances. Within-tolerance calculation accuracy (%). MedPhysBench frozen v1.0 secret-seed test; single answer, no tool execution,max32768output, provider-default temperature/reasoning; infrastructure requests may retry. Calculation denominator600items except Astra/Fable5.1 prespecified stratified half300; checking150planted+150correct per format except those two75+75. Blocked/interrupted/truncated/unparsable answers remain failures; no-verdict checking response neither false alarm nor acceptance. Native v1.0 includes the paper-disclosed NCRP151 convention/item defects; do not relabel as correctedv1.1 or use parenthesized completion-conditional calculation rates.

Metric: Within-tolerance calculation accuracy (%). Source: arxiv.org. Saturation forecast: Rough model projection: around 2026. 12 models tracked.
