What it scores, by house
| Benchmark | House | Score | Evaluated | Scaffold |
|---|---|---|---|---|

These scores are not comparable between houses and are not added up. A score is dated by when it was evaluated, not when the model was released, and a score without its scaffold is not a measurement — which is why both are printed.
