GPT-6 Sol vs. Kimi K3 at the same effort
Both models measured at the same reasoning efforts. This shows whether a lead comes from the model or only from more compute.
| Effort | GPT-6 Sol | Kimi K3 | Gap | Verdict | Test series |
|---|---|---|---|---|---|
| max | 110.5 | 101.2 | 2.9 | tied | 3 |
| Overall index (max vs. max) | 110.5 | 101.2 | 9.3 | GPT-6 Sol ahead |
Gap and verdict compare only the Artificial Analysis test series in which both models are measured at that effort. Tied below 3 points, ahead only beyond two standard errors. The single values rest on all test series of each model, so their difference can deviate from the gap.
