Questions people ask
Which is better, Gemini 3.5 Flash or Muse Spark 1.1?
Muse Spark 1.1 wins four of the eight areas we test: coding, agents, reasoning and long documents. Gemini 3.5 Flash wins math and following instructions. They are level on facts and images and charts.
Which is better for coding?
Muse Spark 1.1. It wins 4 of the 6 coding tests both models report; Gemini 3.5 Flash wins 1, and 1 is a tie.
Which is cheaper?
Gemini 3.5 Flash costs $1.50 per million input tokens and $9.00 per million output tokens; Muse Spark 1.1 costs $1.25 and $4.25. That makes Muse Spark 1.1 about 48% cheaper for the same work.
How do you compare the two?
We use the 34 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 11 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.
