Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.
Kimi K2 has the cleaner overall profile here, landing at 34 versus 32. It is a real lead, but still close enough that category-level strengths matter more than the headline number.
Kimi K2's sharpest advantage is in multimodal & grounded, where it averages 39.5 against 32.4. The single biggest benchmark swing on the page is LongBench v2, 47 to 38. Ministral 3 8B does hit back in instruction following, so the answer changes if that is the part of the workload you care about most.
Pick Kimi K2 if you want the stronger benchmark profile. Ministral 3 8B only becomes the better choice if instruction following is the priority.
