Pick Muse Spark if you want the stronger benchmark profile. GLM-5 only becomes the better choice if mathematics is the priority or you would rather avoid the extra latency and token burn of a reasoning model.

Confidence note. This is a partial-evidence comparison with 20 shared benchmark results across 6 evidence categories; 5 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.

Why this result

Muse Spark is clearly ahead on the BenchAlign aggregate, 71.04 to 66.06. 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 agentic, where it averages 59 against 56.2. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 16.434% to 39.000%. GLM-5 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 GLM-5 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. Muse Spark gives you the larger context window at 262K, compared with 200K for GLM-5.
