GPT-5.6 Sol. It wins 2 of the 2 coding tests both models report; Qwen3.8 2.4T A95B wins none.
Which is cheaper?
GPT-5.6 Sol costs $4.00 per million input tokens and $20.00 per million output tokens; Qwen3.8 2.4T A95B costs $2.00 and $6.00. That makes Qwen3.8 2.4T A95B about 67% 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.
