| Effort | Haiku 5.5 | GLM-5.3 | Gap | Verdict | Test series |
|---|---|---|---|---|---|
| low | 80.8 | 89.3 | 5.6 | GLM-5.3 slightly ahead | 11 |

| Overall index (max vs. max) | 103.4 | 100.7 | 2.7 | level |
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.
