Questions people ask

Which is better, DeepSeek-V2 or DeepSeek-V3?

DeepSeek-V3 wins all two areas where both have results: reasoning and long documents. DeepSeek-V2 wins none.

How do you compare the two?

We use the 62 benchmark tests both models have published scores on. The verdict counts the 2 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 60 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.
