Why this result
Grok 4 is clearly ahead on the BenchAlign aggregate, 60.42 to 47.29. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemma 4 12B is the reasoning model in the pair, while Grok 4 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 Grok 4.
