GPT-5.5on ARC-AGI-2

33.3 to 85.0 the range across every scoreable measurement we hold
51.7 points between the highest and the lowest
70.4 the number the board uses: the lower median, a real row with its own provenance
4 declared configurations, from 1 runner

All 4 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

4 rows, after collapsing 1 that were one measurement written twice. 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.

Snapshot 2026-08-30-62e4e85f043b, manifest dc46131315046f1e, as of 2026-08-30. where only one party has measured a model on a benchmark, this page says so rather than presenting a single number as a reconciliation.
