GPT-4o vs Ministral 3 14B

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

GPT-4o finishes one point ahead overall, 56 to 55. 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.

GPT-4o's sharpest advantage is in agentic, where it averages 51.2 against 48.4. The single biggest benchmark swing on the page is SWE-bench Verified, 20 to 37. Ministral 3 14B does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.

GPT-4o is also the more expensive model on tokens at $2.50 input / $10.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Ministral 3 14B. That is roughly Infinityx on output cost alone.

Quick Verdict

Pick GPT-4o if you want the stronger benchmark profile. Ministral 3 14B only becomes the better choice if knowledge is the priority or you want the cheaper token bill.
