How the score works

A model's score is built only from results that someone other than its maker ran.

  • The scoring set is the benchmarks chosen for this specialty. A benchmark takes part only when at least 5 models have an independent or third-party result on it.
  • Each result is rescaled to 0 to 1, and a model's best setting counts.
  • The score is the average over the benchmarks a model has, times 100.
  • A model ranks only when it has results on enough of them. The rest show "Not enough independent results yet".
  • Self-reported results are shown but never counted.
