Where Gemini 3 Flash stands out and where it falls behind, by the numbers
Gemini 3 Flash has published results on 29 tests compiled by Epoch AI. The yardstick here is its generation: its position among the models released between Mar 22, 2025 and Mar 17, 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.
Where it falls behind
Tests where it sits in the bottom half of its own generation.

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 Gemini 3 Flash better than GLM-5.2?
Across the 18 tests both models took and Epoch AI compiled, Gemini 3 Flash comes out ahead on 8, behind on 10 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.
What is Gemini 3 Flash 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 Gemini 3 Flash are: GeoBench (#1 of 13); ALE-Bench (#2 of 38); SimpleQA Verified (#2 of 28). 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.
