Muse Spark 1.1 wins all seven areas where both have results: coding, agents, reasoning, facts, images and charts, long documents and following instructions. GPT-4o wins none.
Which is better for coding?
Muse Spark 1.1. It wins the one coding test both models report.
Which is cheaper?
GPT-4o costs $5.00 per million input tokens and $15.00 per million output tokens; Muse Spark 1.1 costs $1.25 and $4.25. That makes Muse Spark 1.1 about 73% cheaper for the same work.
How do you compare the two?
We use the 16 benchmark tests both models have published scores on. The verdict counts the 12 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 4 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.
