Confidence note. This is a partial-evidence comparison with 18 shared benchmark results across 6 evidence categories; 3 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.

Why this result

MiMo-V2.5-Pro has the cleaner BenchAlign overall profile here, landing at 70.19 versus 68.59. It is a real lead, but still close enough that category-level strengths matter more than the headline number.

MiMo-V2.5-Pro is the reasoning model in the pair, while Claude Opus 4.6 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.
