Deep
Scores are reported (%, maximum 100); higher is better. BenchGecko collects ARC AI2 scores from Epoch AI and refreshes them daily; the leaderboard on this page shows the current top models.
Expert
Compare models only on the same benchmark version and settings. A benchmark separates models well while scores are spread out; when top models bunch together near the maximum, it stops telling them apart.
