Winner · 4/8 categoriesGemma 4 E4B· Kimi K2.5 (Reasoning)
Pick Kimi K2.5 (Reasoning) if you want the stronger benchmark profile. Gemma 4 E4B only becomes the better choice if its workflow or ecosystem matters more than the raw scoreboard.
Kimi K2.5 (Reasoning) is clearly ahead on the aggregate, 76 to 47. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Kimi K2.5 (Reasoning)'s sharpest advantage is in reasoning, where it averages 74.3 against 25.4. The single biggest benchmark swing on the page is BBH, 33.1% to 91%.
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.
