Pick Claude 4.1 Opus if you want the stronger benchmark profile. Gemma 4 E2B only becomes the better choice if you want the stronger reasoning-first profile.
Claude 4.1 Opus is clearly ahead on the aggregate, 62 to 39. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Claude 4.1 Opus's sharpest advantage is in reasoning, where it averages 71.3 against 19.1. The single biggest benchmark swing on the page is BBH, 81% to 21.9%.
Gemma 4 E2B is the reasoning model in the pair, while Claude 4.1 Opus 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. Claude 4.1 Opus gives you the larger context window at 200K, compared with 128K for Gemma 4 E2B.
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.
