Every score
one row per source and configuration — nothing averaged away
| Benchmark | Score | Configuration | Source | Run |
|---|---|---|---|---|
| FrontierMath-v1 | 60.0 ±16.3 | high | Epoch AI | 2025-10-08 |
| FrontierMath-Tiers-1-3-v2 | 55.8 ±2.9 | high | Epoch AI | 2026-06-12 |
| FrontierMath-Tier-4-2025-07-01 | 14.6 ±5.1 | high | Epoch AI | 2025-10-09 |
| FrontierMath-Tier-4-v2 | 19.5 ±6.3 | high | Epoch AI | 2026-06-12 |
The leading figure for a benchmark is the median across its configurations, so one heroic high-effort run cannot set the number.
