Gemma 4 E2B· o1

Quick Verdict

Pick o1 if you want the stronger benchmark profile. Gemma 4 E2B only becomes the better choice if you want the cheaper token bill.

o1 is clearly ahead on the aggregate, 64 to 39. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

o1's sharpest advantage is in reasoning, where it averages 78.1 against 19.1. The single biggest benchmark swing on the page is MRCRv2, 19.1% to 77%.

o1 is also the more expensive model on tokens at $15.00 input / $60.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Gemma 4 E2B. That is roughly Infinityx on output cost alone. o1 gives you the larger context window at 200K, compared with 128K for Gemma 4 E2B.

Decision framing

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.
