    <abstract>We present NusaBERT, a multilingual model built on IndoBERT and tailored for Indonesia‘s diverse languages. By expanding vocabulary and pre-training on a regional corpus, NusaBERT achieves state-of-the-art performance on Indonesian NLU benchmarks, enhancing IndoBERT‘s multilingual capability. This study also addresses NusaBERT‘s limitations and encourages further research on Indonesia‘s underrepresented languages.</abstract>
