GPT-4o vs Ministral 3 8B

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

GPT-4o is clearly ahead on the aggregate, 56 to 32. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-4o's sharpest advantage is in multimodal & grounded, where it averages 72.2 against 32.4. The single biggest benchmark swing on the page is MMMU-Pro, 74 to 27.

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 8B. That is roughly Infinityx on output cost alone.

Quick Verdict

Pick GPT-4o if you want the stronger benchmark profile. Ministral 3 8B only becomes the better choice if you want the cheaper token bill.
