Ministral 3 14B (Reasoning) vs GPT-4o mini

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 52. 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 reasoning, where it averages 69.2 against 49.4. The single biggest benchmark swing on the page is SWE-bench Pro, 36 to 65. GPT-4o mini does hit back in coding, so the answer changes if that is the part of the workload you care about most.

GPT-4o mini 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 14B (Reasoning). That is roughly Infinityx on output cost alone. Ministral 3 14B (Reasoning) is the reasoning model in the pair, while GPT-4o mini 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-4o mini only becomes the better choice if coding is the priority or you would rather avoid the extra latency and token burn of a reasoning model.
