Questions people ask
Which is better, Gemini 3.1 Pro or Muse Spark 1.1?
Gemini 3.1 Pro wins four of the eight areas we test: reasoning, facts, math and long documents. Muse Spark 1.1 wins coding, agents and images and charts, and costs 61% less. They are level on following instructions.
Which is better for coding?
Muse Spark 1.1. It wins 4 of the 6 coding tests both models report; Gemini 3.1 Pro wins none, and 2 are ties.
Which is cheaper?
Gemini 3.1 Pro costs $2.00 per million input tokens and $12.00 per million output tokens; Muse Spark 1.1 costs $1.25 and $4.25. That makes Muse Spark 1.1 about 61% cheaper for the same work.
How do you compare the two?
We use the 42 benchmark tests both models have published scores on. The verdict counts the 24 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 18 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.
