How smart is MiniMax-M2.5?
MiniMax-M2.5 is a model from MiniMax, released on Feb 12, 2026. Its SI-IQ is 118 (90% interval 105–132), estimated from 2 benchmark results by 1 independent evaluators.
This model has fewer than 5 independent benchmark results or fewer than 2 different evaluators, so it is shown but not ranked.

Ability by area (SI-IQ, 90% interval)
Every benchmark result we used
Each score is one value exactly as the source published it: for Epoch AI the best of its run settings, for OpenRouter the median hosting provider (the developer's own hosting when it ran the test). “Implied SI-IQ” is the ability that this single result points to; the overall SI-IQ is their precision-weighted average.

Human preference (Arena)
On the Arena leaderboard, where people vote between two anonymous answers, MiniMax-M2.5 has a rating of 1,391 (1,387–1,395) from 42,815 votes (published Oct 15, 2026). Human preference is a different measure from benchmark ability and is not part of SI-IQ. Arena (Hugging Face)
