Which is better for coding?
Muse Spark 1.1. It wins 5 of the 6 coding tests both models report; Kimi K2.6 wins 1.
Which is cheaper?
Kimi K2.6 costs $0.95 per million input tokens and $4.00 per million output tokens; Muse Spark 1.1 costs $1.25 and $4.25. That makes Kimi K2.6 about 10% cheaper for the same work.
How do you compare the two?
We use the 33 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 10 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.
