Gemma 4 26B A4B makes more sense if coding is the priority or you need the larger 256K context window, while Gemma 4 E4B is the cleaner fit if knowledge is the priority.
Gemma 4 26B A4B and Gemma 4 E4B sit in the same Gemma 4 family. This page is less about two unrelated model lineages and more about how the siblings trade off on benchmark shape, token costs, and practical limits like context window.
Gemma 4 26B A4B is clearly ahead on the aggregate, 64 to 47. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemma 4 26B A4B's sharpest advantage is in coding, where it averages 77.1 against 52. The single biggest benchmark swing on the page is BBH, 64.8% to 33.1%. 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 26B A4B gives you the larger context window at 256K, compared with 128K for Gemma 4 E4B.
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.
