Winner · 3/8 categoriesGemma 4 E4B· Grok 4
Pick Grok 4 if you want the stronger benchmark profile. Gemma 4 E4B only becomes the better choice if knowledge is the priority or you want the stronger reasoning-first profile.
Grok 4 is clearly ahead on the aggregate, 68 to 47. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Grok 4's sharpest advantage is in reasoning, where it averages 59.6 against 25.4. The single biggest benchmark swing on the page is BBH, 33.1% to 83%. Gemma 4 E4B does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
Gemma 4 E4B is the reasoning model in the pair, while Grok 4 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.
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.
