Where Kimi K2.7 Code stands out and where it falls behind, by the numbers
Kimi K2.7 Code has published results on 18 tests compiled by Epoch AI. The yardstick here is its generation: its position among the models released between Sep 15, 2025 and Sep 10, 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.

In the ROO3 AI Benchmark, ordered by the Epoch AI ECI, Kimi K2.7 Code ranks #58 out of 267 models, with an ECI of 149.87. The ECI is a composite index that combines several hard benchmarks into a single scale. The position changes when a new model comes out, and the page is refreshed six times a day.
Is Kimi K2.7 Code better than GPT-5.1?
Across the 11 tests both models took and Epoch AI compiled, Kimi K2.7 Code comes out ahead on 7, behind on 4 and tied on 0. 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.
