Gemini 3.1 Pro Previewon ARC-AGI-2

77.1 to 77.1 the range across every scoreable measurement we hold

0.0 points between the highest and the lowest

77.1 the number the board uses: the lower median, a real row with its own provenance

1 declared configuration, from 1 runner

All 2 scoreable measurements here come from one runner under one declared configuration, so nothing on this page explains why they differ. That is the finding.

Two measurements, one declared configuration, +0.0 points apart. 2 rows here agree on everything the record states, the system identity included, and disagree on the number: 77.1, 77.1. Something moved the score and no source we hold says what. The board resolves it by taking the lower median, which is a rule and not an explanation, so it is named here rather than quietly settled. This happens in 14 of 321 claim pages.

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.

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.
