Which is better for coding?
Qwen3 Coder Next. It wins 2 of the 3 coding tests both models report; DeepSeek-V3 wins 1.
Which is cheaper?
DeepSeek-V3 costs $0.24 per million input tokens and $0.90 per million output tokens; Qwen3 Coder Next costs $0.30 and $1.50. That makes DeepSeek-V3 about 37% cheaper for the same work.
How do you compare the two?
We use the 16 benchmark tests both models have published scores on. The verdict counts the 12 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.
