Where DeepSeek-V4-Flash stands out and where it falls behind, by the numbers
DeepSeek-V4-Flash has published results on 6 tests compiled by Epoch AI. The yardstick here is its generation: its position among the models released between Jul 28, 2025 and Jul 23, 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.

What people ask about DeepSeek-V4-Flash
Where does DeepSeek-V4-Flash rank among AI models?
In the ROO3 AI Benchmark, ordered by the Epoch AI ECI, DeepSeek-V4-Flash ranks #84 out of 267 models, with an ECI of 146.05. 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 DeepSeek-V4-Flash better than GPT-5.4 Nano?
Across the 5 tests both models took and Epoch AI compiled, DeepSeek-V4-Flash comes out ahead on 1, 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.
