GPT-4.1 vs Ministral 3 8B (Reasoning)

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

GPT-4.1 is clearly ahead on the aggregate, 65 to 36. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

GPT-4.1's sharpest advantage is in multimodal & grounded, where it averages 73.6 against 33.4. The single biggest benchmark swing on the page is MMLU, 90.2 to 30. Ministral 3 8B (Reasoning) does hit back in mathematics, so the answer changes if that is the part of the workload you care about most.

GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.00 input / $0.00 output per 1M tokens for Ministral 3 8B (Reasoning). That is roughly Infinityx on output cost alone. Ministral 3 8B (Reasoning) is the reasoning model in the pair, while GPT-4.1 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. GPT-4.1 gives you the larger context window at 1M, compared with 128K for Ministral 3 8B (Reasoning).

Quick Verdict

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