BN-VN3S benchmarks 946,696 Vietnamese articles

BN-VN3S packages metadata and evaluation resources for 946,696 Vietnamese news articles across 10 categories, with its new Hugging Face release reporting 92.42% macro-F1 for BiGRU versus 87.98% for PhoBERT. The repository does not redistribute article text—users must reconstruct it from publisher URLs—and says PhoBERT held up better under temporal shift despite losing in-distribution. For builders reading the widening global model race, this is a useful warning that the most expensive architecture can lose the headline score while still buying the robustness deployment actually needs.
