Questions people ask
Which is better, A.X-K2 or Motif-3?
Motif-3 wins four of the five areas where both have results: coding, agents, facts and long documents. A.X-K2 wins reasoning.
Which is better for coding?
Motif-3. It wins 2 of the 2 coding tests both models report; A.X-K2 wins none.
How do you compare the two?
We use the 14 benchmark tests both models have published scores on. The verdict counts the 10 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 4 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.
