Winner · 3/8 categoriesGemma 4 E4B· o3-pro
Pick o3-pro if you want the stronger benchmark profile. Gemma 4 E4B only becomes the better choice if coding is the priority.
o3-pro is clearly ahead on the aggregate, 67 to 47. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
o3-pro's sharpest advantage is in reasoning, where it averages 81.8 against 25.4. The single biggest benchmark swing on the page is BBH, 33.1% to 89%. Gemma 4 E4B does hit back in coding, so the answer changes if that is the part of the workload you care about most.
o3-pro gives you the larger context window at 200K, 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.
