Ministral 3 14B (Reasoning) vs Llama 3.1 405B

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

Ministral 3 14B (Reasoning) finishes one point ahead overall, 60 to 59. That is enough to call, but not enough to treat as a blowout. This matchup comes down to a few meaningful edges rather than one model dominating the board.

Ministral 3 14B (Reasoning)'s sharpest advantage is in multimodal & grounded, where it averages 71.5 against 62.3. The single biggest benchmark swing on the page is MMMU-Pro, 71 to 60. Llama 3.1 405B does hit back in coding, 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 Llama 3.1 405B 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. Llama 3.1 405B 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.
