GDP.pdf (Mean Criteria Pass Rate)
Professional Work · 2026-07-24
GDP.pdf scored as mean criteria pass rate: the fraction of rubric conditions satisfied across tasks, averaged over completed runs, rather than the strict per-prompt accuracy the Surge AI leaderboard reports. Anthropic reports this metric from an internal harness, so its scores are far higher than leaderboard accuracy and are not comparable with it.
