Pick Muse Spark if you want the stronger benchmark profile. LFM2.5-230M only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
Muse Spark is clearly ahead on the provisional aggregate, 80 to 17. 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 20.3.
Muse Spark is the reasoning model in the pair, while LFM2.5-230M 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 32K for LFM2.5-230M.
Muse Spark is ahead on BenchLM's provisional leaderboard, 80 to 17.
Muse Spark has the edge for knowledge tasks in this comparison, averaging 50.4 versus 20.3. LFM2.5-230M stays close enough that the answer can still flip depending on your workload.
