DeepSeek V3.1 (Reasoning) vs Ministral 3 8B

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

DeepSeek V3.1 (Reasoning) is clearly ahead on the aggregate, 41 to 32. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

DeepSeek V3.1 (Reasoning)'s sharpest advantage is in agentic, where it averages 44.2 against 28.9. The single biggest benchmark swing on the page is LongBench v2, 57 to 38.

DeepSeek V3.1 (Reasoning) is the reasoning model in the pair, while Ministral 3 8B 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 DeepSeek V3.1 (Reasoning) if you want the stronger benchmark profile. Ministral 3 8B only becomes the better choice if you would rather avoid the extra latency and token burn of a reasoning model.
