o4-mini (high) vs Ministral 3 14B (Reasoning)

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

o4-mini (high) has the cleaner overall profile here, landing at 63 versus 60. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

o4-mini (high)'s sharpest advantage is in knowledge, where it averages 61.2 against 52.1. The single biggest benchmark swing on the page is HumanEval, 74 to 62. Ministral 3 14B (Reasoning) does hit back in multimodal & grounded, so the answer changes if that is the part of the workload you care about most.

Ministral 3 14B (Reasoning) is the reasoning model in the pair, while o4-mini (high) 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. o4-mini (high) gives you the larger context window at 200K, compared with 128K for Ministral 3 14B (Reasoning).

Quick Verdict

Pick o4-mini (high) if you want the stronger benchmark profile. Ministral 3 14B (Reasoning) only becomes the better choice if multimodal & grounded is the priority or you want the stronger reasoning-first profile.
