How do you compare the two?
We use the 6 benchmark tests both models have published scores on. The verdict counts the 5 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 1 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
