GPT-4o mini
GPT-4o mini (OpenAI) was released on Jul 18, 2024. In the Epoch AI capability ranking (ECI), it ranks #176 out of 267 models, with 126.58. Against models of the same generation, its best result is on GSM8K: 91.3%, #1 of 27.
Where GPT-4o mini stands out and where it falls behind, by the numbers
GPT-4o mini has published results on 23 tests compiled by Epoch AI. The yardstick here is its generation: its position among the models released between Oct 22, 2023 and Oct 16, 2024 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.
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, GPT-4o mini ranks #176 out of 267 models, with an ECI of 126.58. 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 GPT-4o mini better than Claude 3 Opus?
Across the 11 tests both models took and Epoch AI compiled, GPT-4o mini comes out ahead on 2, behind on 8 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.
What is GPT-4o mini best at?
Against models of the same generation (released up to 9 months before and up to 3 months after it), the best relative results of GPT-4o mini are: GSM8K (#1 of 27); PIQA (#1 of 13); BoolQ (#1 of 9). The yardstick is its position among the models of that period that took the same test.
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.
