Why this result
Gemini 3 Flash has the cleaner BenchAlign overall profile here, landing at 60.49 versus 58.01. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Gemini 3 Flash's sharpest advantage is in mathematics, where it averages 27.8 against 6.4. The single biggest benchmark swing on the page is FrontierMath v2 (Tiers 1-3), 35.640% to 8.481%.
Gemini 3 Flash is also the more expensive model on tokens at $0.50 input / $3.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Qwen3 235B 2507 (Reasoning). That is roughly Infinityx on output cost alone. Qwen3 235B 2507 (Reasoning) is the reasoning model in the pair, while Gemini 3 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 3 Flash gives you the larger context window at 1M, compared with 128K for Qwen3 235B 2507 (Reasoning).
