Questions people ask
Which is better, DeepSeek-R1 0528-Qwen3-8B or o3?
o3 wins four of the five areas where both have results: coding, reasoning, long documents and following instructions. DeepSeek-R1 0528-Qwen3-8B wins none. They are level on facts.
Which is better for coding?
o3. It wins 2 of the 2 coding tests both models report; DeepSeek-R1 0528-Qwen3-8B wins none.
How do you compare the two?
We use the 17 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 8 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.
