GPT-4.1 nano vs Ministral 3 8B

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

GPT-4.1 nano is clearly ahead on the aggregate, 49 to 32. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-4.1 nano's sharpest advantage is in reasoning, where it averages 74.1 against 36.1. The single biggest benchmark swing on the page is MMLU, 80.1 to 28. Ministral 3 8B does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.

GPT-4.1 nano is also the more expensive model on tokens at $0.10 input / $0.40 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. GPT-4.1 nano gives you the larger context window at 1M, compared with 128K for Ministral 3 8B.

Quick Verdict

Pick GPT-4.1 nano if you want the stronger benchmark profile. Ministral 3 8B only becomes the better choice if mathematics is the priority or you want the cheaper token bill.
