Questions people ask
Which is better, Apertus 8B Instruct or Tiny Aya Global?
Apertus 8B Instruct wins two of the five areas where both have results: facts and following instructions. Tiny Aya Global wins reasoning. They are level on coding and long documents.
Which is better for coding?
Neither. All 2 coding tests both models report are ties.
How do you compare the two?
We use the 13 benchmark tests both models have published scores on. The verdict counts the 9 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.
