Gemma 4 E4B· GPT-OSS 120B

Quick Verdict

Pick GPT-OSS 120B if you want the stronger benchmark profile. Gemma 4 E4B only becomes the better choice if coding is the priority or you want the stronger reasoning-first profile.

GPT-OSS 120B 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.

GPT-OSS 120B's sharpest advantage is in reasoning, where it averages 55.4 against 25.4. The single biggest benchmark swing on the page is BBH, 33.1% to 73%. Gemma 4 E4B does hit back in coding, so the answer changes if that is the part of the workload you care about most.

Gemma 4 E4B is the reasoning model in the pair, while GPT-OSS 120B 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.

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.
