GPT-5 mini vs Ministral 3 3B

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

GPT-5 mini is clearly ahead on the aggregate, 69 to 27. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-5 mini's sharpest advantage is in multimodal & grounded, where it averages 83.8 against 30.4. The single biggest benchmark swing on the page is AIME 2023, 90 to 23.

GPT-5 mini is the reasoning model in the pair, while Ministral 3 3B 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.

Quick Verdict

Pick GPT-5 mini if you want the stronger benchmark profile. Ministral 3 3B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
