Open the original- What it measures
- The official leaderboard page is rendered by JavaScript. This mirror reproduces its table with an import date of 2026-05-06 and adds a written summary. The average covers the leaderboard's English tests.
- What it does not show
- A third-party snapshot from May 2026, not the official page. It lists models that a 2025 paper did not, so it is not directly comparable with the paper's table. Averages can change as systems are added or rescored.
