Questions people ask
Which is better, Apriel-v1.5-15B-Thinker or HyperCLOVA X SEED Think (32B)?
Apriel-v1.5-15B-Thinker wins three of the five areas where both have results: reasoning, long documents and following instructions. HyperCLOVA X SEED Think (32B) wins none. They are level on coding and facts.
Which is better for coding?
Neither. They win 1 coding test each of the 2 both models report.
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.
