GPT-5.5 Pro Pre Releaseon FrontierMath

51.0 to 52.4 the range across every scoreable measurement we hold
1.4 points between the highest and the lowest
51.0 the number the board uses: the lower median, a real row with its own provenance
2 declared configurations, from 1 runner

All 2 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

2 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.
