Why this result
Gemma 4 31B has the cleaner BenchAlign overall profile here, landing at 61.08 versus 58.88. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Gemma 4 31B's sharpest advantage is in knowledge, where it averages 52.9 against 38.8. The single biggest benchmark swing on the page is HLE, 8.1% to 26.5%. DeepSeek V4 Flash does hit back in coding, so the answer changes if that is the part of the workload you care about most.
DeepSeek V4 Flash is also the more expensive model on tokens at $0.14 input / $0.28 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Gemma 4 31B. That is roughly Infinityx on output cost alone. Gemma 4 31B is the reasoning model in the pair, while DeepSeek V4 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. DeepSeek V4 Flash gives you the larger context window at 1M, compared with 256K for Gemma 4 31B.
