Questions people ask
Which is better, Apertus 8B Instruct or Apriel-v1.6-15B-Thinker?
Apriel-v1.6-15B-Thinker wins all five areas where both have results: coding, reasoning, facts, long documents and following instructions. Apertus 8B Instruct wins none.
Which is better for coding?
Apriel-v1.6-15B-Thinker. It wins 2 of the 2 coding tests both models report; Apertus 8B Instruct wins none.
How do you compare the two?
We use the 12 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 3 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.
