Questions people ask
Which is better, Gemini 3.1 Pro or Muse Spark 1.3?
Muse Spark 1.3 wins six of the eight areas we test: coding, agents, reasoning, images and charts, math and long documents. Gemini 3.1 Pro wins following instructions. They are level on facts.
Which is better for coding?
Muse Spark 1.3. It wins 4 of the 5 coding tests both models report; Gemini 3.1 Pro wins none, and 1 is a tie.
Which is cheaper?
Gemini 3.1 Pro costs $2.00 per million input tokens and $12.00 per million output tokens; Muse Spark 1.3 costs $1.25 and $4.25. That makes Muse Spark 1.3 about 61% 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.
