Every score
one row per source and configuration — nothing averaged away
| Benchmark | Score | Configuration | Source | Run |
|---|---|---|---|---|
| LiveBench | 78.3 | xhigh · 23 runs | LiveBench | 2026-06-25 |
| Furniture Assembly | 20.8 ±5.2 | xhigh | Epoch AI | 2026-09-24 |
The leading figure for a benchmark is the median across its configurations, so one heroic high-effort run cannot set the number.
