Every score
one row per source and configuration — nothing averaged away
| Benchmark | Score | Configuration | Source | Run |
|---|---|---|---|---|
| OTIS Mock AIME 2024-2025 | 82.2 ±5.8 | default | Epoch AI | 2026-08-28 |
| GPQA diamond | 73.2 ±3.2 | default | Epoch AI | 2026-08-06 |
The leading figure for a benchmark is the median across its configurations, so one heroic high-effort run cannot set the number.
