Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Gemini 2.5 Flash is clearly ahead on the aggregate, 49 to 31. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Gemini 2.5 Flash's sharpest advantage is in multimodal & grounded, where it averages 67.7 against 30.4. The single biggest benchmark swing on the page is MMMU-Pro, 69 to 25.
Gemini 2.5 Flash is also the more expensive model on tokens at $0.15 input / $0.60 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Ministral 3 3B (Reasoning). That is roughly Infinityx on output cost alone. Ministral 3 3B (Reasoning) is the reasoning model in the pair, while Gemini 2.5 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 2.5 Flash gives you the larger context window at 1M, compared with 128K for Ministral 3 3B (Reasoning).
Pick Gemini 2.5 Flash if you want the stronger benchmark profile. Ministral 3 3B (Reasoning) only becomes the better choice if you want the cheaper token bill or you want the stronger reasoning-first profile.
