Questions people ask
Which is better, Kimi K2.6 or MiMo V2.5?
Kimi K2.6 wins all eight areas we test: coding, agents, reasoning, facts, images and charts, math, long documents and following instructions. MiMo V2.5 wins none, but costs 93% less.
Which is better for coding?
Kimi K2.6. It wins 7 of the 7 coding tests both models report; MiMo V2.5 wins none.
Which is cheaper?
Kimi K2.6 costs $0.95 per million input tokens and $4.00 per million output tokens; MiMo V2.5 costs $0.11 and $0.22. That makes MiMo V2.5 about 93% cheaper for the same work.
How do you compare the two?
We use the 35 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 12 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.
