Ministral 3 14B (Reasoning) vs GPT-OSS 120B

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

Ministral 3 14B (Reasoning) is clearly ahead on the aggregate, 60 to 48. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Ministral 3 14B (Reasoning)'s sharpest advantage is in multimodal & grounded, where it averages 71.5 against 48.8. The single biggest benchmark swing on the page is MMMU-Pro, 71 to 42.

Ministral 3 14B (Reasoning) is the reasoning model in the pair, while GPT-OSS 120B 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 Ministral 3 14B (Reasoning) if you want the stronger benchmark profile. GPT-OSS 120B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
