Why this result

Gemma 4 12B has the cleaner BenchAlign overall profile here, landing at 47.29 versus 44.97. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

Gemma 4 12B's sharpest advantage is in mathematics, where it averages 77.5 against 1.7. The single biggest benchmark swing on the page is GPQA, 59.1% to 78.8%.

Gemma 4 12B is the reasoning model in the pair, while DeepSeek V3 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. Gemma 4 12B gives you the larger context window at 256K, compared with 128K for DeepSeek V3.
