| Benchmark | Score | Configuration | Source | Run |
|---|---|---|---|---|
| Chess Puzzles | 60.0 ±4.9 | xhigh | Epoch AI | 2026-10-14 |
| FrontierMath-Tiers-1-3-v2 | 74.0 ±2.6 | xhigh | Epoch AI | 2026-06-13 |
| FrontierMath-Tier-4-v2 | 46.0 ±7.8 | xhigh | Epoch AI | 2026-06-13 |
The leading figure for a benchmark is the median across its configurations, so one heroic high-effort run cannot set the number.
