Score: 100 = perfect, 0 = no better than guessing. The bar is the 95% range. Select a model to see everything behind its row.
Wins: a model wins a column when it is in the top two for that column (score, accuracy, calibration gap, cost or speed). The table is sorted by most wins, then by score. =3 means tied on wins.

automation at 95% accuracy
Share of questions each model can answer alone and stay 95% right. It answers only above its confidence cut-off; the rest go to a person.
No model reaches 95% accuracy at any confidence on this task. Keep a person in the loop.
