Baichuan 2-7B
Baichuan 2-7B (Baichuan) was released on Sep 20, 2023. In the Epoch AI capability ranking (ECI), it ranks #247 out of 267 models, with 96.45.
Where Baichuan 2-7B stands out and where it falls behind, by the numbers
Baichuan 2-7B has published results on 7 tests compiled by Epoch AI. The yardstick here is its generation: its position among the models released between Dec 24, 2022 and Dec 19, 2023 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.

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.
