Winner · 4/8 categoriesDeepSeek V3.1 (Reasoning)· Gemma 4 31B
Pick Gemma 4 31B if you want the stronger benchmark profile. DeepSeek V3.1 (Reasoning) only becomes the better choice if its workflow or ecosystem matters more than the raw scoreboard.
Gemma 4 31B is clearly ahead on the aggregate, 73 to 43. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemma 4 31B's sharpest advantage is in coding, where it averages 80 against 19. The single biggest benchmark swing on the page is LiveCodeBench, 16% to 80%.
Gemma 4 31B gives you the larger context window at 256K, compared with 128K for DeepSeek V3.1 (Reasoning).
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.
