Grok 3 [Beta] vs Ministral 3 3B (Reasoning)

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

Grok 3 [Beta] is clearly ahead on the aggregate, 38 to 31. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Grok 3 [Beta]'s sharpest advantage is in multimodal & grounded, where it averages 43.2 against 30.4. The single biggest benchmark swing on the page is HumanEval, 34 to 16. Ministral 3 3B (Reasoning) does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.

Ministral 3 3B (Reasoning) is the reasoning model in the pair, while Grok 3 [Beta] 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 Grok 3 [Beta] if you want the stronger benchmark profile. Ministral 3 3B (Reasoning) only becomes the better choice if instruction following is the priority or you want the stronger reasoning-first profile.
