Winner · 1/8 categoriesGemini 1.5 Pro· Gemma 4 26B A4B
Pick Gemma 4 26B A4B if you want the stronger benchmark profile. Gemini 1.5 Pro only becomes the better choice if knowledge is the priority or you need the larger 2M context window.
Gemma 4 26B A4B is clearly ahead on the aggregate, 64 to 50. 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 16.5. The single biggest benchmark swing on the page is LiveCodeBench, 22% to 77.1%. Gemini 1.5 Pro 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 is the reasoning model in the pair, while Gemini 1.5 Pro 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. Gemini 1.5 Pro gives you the larger context window at 2M, compared with 256K for Gemma 4 26B A4B.
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.
