Pick Gemini 2.5 Flash if you want the stronger benchmark profile. Gemma 4 E4B only becomes the better choice if coding is the priority or you want the cheaper token bill.
Gemini 2.5 Flash has the cleaner overall profile here, landing at 50 versus 47. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Gemini 2.5 Flash's sharpest advantage is in reasoning, where it averages 62.1 against 25.4. The single biggest benchmark swing on the page is MRCRv2, 68% to 25.4%. Gemma 4 E4B does hit back in coding, so the answer changes if that is the part of the workload you care about most.
Gemini 2.5 Flash is also the more expensive model on tokens at $0.15 input / $0.60 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Gemma 4 E4B. That is roughly Infinityx on output cost alone. Gemma 4 E4B is the reasoning model in the pair, while Gemini 2.5 Flash 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 2.5 Flash gives you the larger context window at 1M, 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.
