Questions people ask
Which is better, GPT-5.6 Sol or Qwen3.6 27B?
GPT-5.6 Sol wins seven of the eight areas we test: coding, agents, reasoning, images and charts, math, long documents and following instructions. Qwen3.6 27B wins none, but costs 83% less. They are level on facts.
Which is better for coding?
GPT-5.6 Sol. It wins 6 of the 6 coding tests both models report; Qwen3.6 27B wins none.
Which is cheaper?
GPT-5.6 Sol costs $4.00 per million input tokens and $20.00 per million output tokens; Qwen3.6 27B costs $0.60 and $3.60. That makes Qwen3.6 27B about 83% cheaper for the same work.
How do you compare the two?
We use the 32 benchmark tests both models have published scores on. The verdict counts the 23 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 9 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.
