MiniMax-M2.5
MiniMax-M2.5 (MiniMax) was released on Feb 12, 2026. In the Epoch AI capability ranking (ECI), it ranks #75 out of 267 models, with 146.67. On Arena, which measures human preference in blind comparisons, it has 1,393 ELO points (#184).
Where MiniMax-M2.5 stands out and where it falls behind, by the numbers
MiniMax-M2.5 has published results on 9 tests compiled by Epoch AI. The yardstick here is its generation: its position among the models released between May 18, 2025 and May 13, 2026 that took the same test. Against the whole archive, which includes 2023 models, a recent release lands near the top of almost everything, and that says nothing.
Where it stands out
Tests where it sits in the top third of its own generation.
It is not in the top third of its generation on any test with 6 or more models compared.
Where it falls behind
Tests where it sits in the bottom half of its own generation.

Across the 7 tests both models took and Epoch AI compiled, MiniMax-M2.5 comes out ahead on 0, behind on 6 and tied on 1. It is a test-by-test count with no weighting: a win in math counts the same as a win in coding. To choose between the two, look at the tests that resemble your own use.
Where do the numbers on this page come from?
From the same three sources as the ranking, all openly licensed: Epoch AI (ECI and individual tests, CC BY 4.0), Arena (human-preference ELO, CC BY 4.0) and LiveBench (overall average, CC BY-SA 4.0). ROO3 does not measure any model. When the page shows a figure published by the maker itself, it appears in the written analysis, labeled as the maker's, and never enters the ranking.
