Why this result
Muse Spark is clearly ahead on the BenchAlign aggregate, 71.04 to 58.88. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Muse Spark's sharpest advantage is in knowledge, where it averages 50.4 against 38.8. The single biggest benchmark swing on the page is HLE, 8.1% to 50.4%. DeepSeek V4 Flash does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.
Muse Spark is the reasoning model in the pair, while DeepSeek V4 Flash is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. DeepSeek V4 Flash gives you the larger context window at 1M, compared with 262K for Muse Spark.
