Pick LFM2.5-350M if you want the stronger benchmark profile. Gemma 3 27B only becomes the better choice if knowledge is the priority.
LFM2.5-350M is clearly ahead on the aggregate, 39 to 34. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
LFM2.5-350M's sharpest advantage is in instruction following, where it averages 77 against 67. The single biggest benchmark swing on the page is MMLU-Pro, 50% to 20.0%. Gemma 3 27B does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
BenchLM keeps the benchmark table and the operator tradeoffs on the same page so a better score does not hide a materially slower, pricier, or smaller-context model.
Runtime metrics show N/A when BenchLM does not have a sourced snapshot for that exact model. The scoring rules and freshness policy are documented on the methodology page.
