Which is better for coding?
DeepSeek-V4-Pro. It wins 3 of the 3 coding tests both models report; Solar Pro 3 wins none.
Which is cheaper?
DeepSeek-V4-Pro costs $0.43 per million input tokens and $0.87 per million output tokens; Solar Pro 3 costs $0.15 and $0.60. That makes Solar Pro 3 about 43% cheaper for the same work.
How do you compare the two?
We use the 17 benchmark tests both models have published scores on. The verdict counts the 13 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.
