Pick Gemma 4 E4B if you want the stronger benchmark profile. Z-1 only becomes the better choice if reasoning is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
Gemma 4 E4B has the cleaner overall profile here, landing at 47 versus 44. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Gemma 4 E4B's sharpest advantage is in coding, where it averages 52 against 27.6. The single biggest benchmark swing on the page is BBH, 33.1% to 74%. Z-1 does hit back in reasoning, 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 Z-1 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.
