GPT-5.4 (2026-03-05)on OTIS Mock AIME 2024-2025

57.8 to 97.8 the range across every scoreable measurement we hold
40.0 points between the highest and the lowest
95.3 the number the board uses: the lower median, a real row with its own provenance
5 declared configurations, from 1 runner

All 5 scoreable measurements here come from ONE runner, so this is not a reconciliation and is not presented as one. What it shows is how far a single runner's number moves when the model is run differently.

Every measurement

5 rows. Best first. the board takes the LOWER MEDIAN of the scoreable measurements, which is a real row with its own interval and provenance rather than an interpolated average. a vendor self-report is shown beside the independent numbers and is never one of them; it cannot move a rank.
