Questions people ask
Which is better, GPT-5.6 Sol or MiniMax M3?
GPT-5.6 Sol wins six of the eight areas we test: coding, agents, reasoning, images and charts, math and long documents. MiniMax M3 wins none, but costs 94% less. They are level on facts and following instructions.
Which is better for coding?
GPT-5.6 Sol. It wins 7 of the 7 coding tests both models report; MiniMax M3 wins none.
Which is cheaper?
GPT-5.6 Sol costs $4.00 per million input tokens and $20.00 per million output tokens; MiniMax M3 costs $0.30 and $1.20. That makes MiniMax M3 about 94% cheaper for the same work.
How do you compare the two?
We use the 40 benchmark tests both models have published scores on. The verdict counts the 27 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 13 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.
