Questions people ask
Which is better, Claude Opus 4.6 or Muse Spark 1.1?
Muse Spark 1.1 wins five of the eight areas we test: coding, agents, reasoning, facts and following instructions. Claude Opus 4.6 wins math. They are level on images and charts and long documents.
Which is better for coding?
Muse Spark 1.1. It wins 3 of the 5 coding tests both models report; Claude Opus 4.6 wins 1, and 1 is a tie.
Which is cheaper?
Claude Opus 4.6 costs $5.00 per million input tokens and $25.00 per million output tokens; Muse Spark 1.1 costs $1.25 and $4.25. That makes Muse Spark 1.1 about 82% 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 21 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.
