What it measures vs what it misses
✓ Measures
Very hard expert-level knowledge and reasoning.
✗ Misses
Adjacent capabilities, subjective preference, latency, and cost.
Why this countsIt is one of the cleaner reads on deliberate reasoning strength rather than style or popularity.Same-test ruleThis percentile only compares models inside the exact benchmark/version group shown here. It is not a universal score.What it missesIt still misses product usability, latency, and whether the model stays correct in messy real workflows.
