arXiv:2510.21372v2 Announce Type: replace Abstract: Transformer-based models have advanced NLP, yet Hebrew still lacks a RoBERTa encoder that is trained at scale and released in both base and large variants. We present HalleluBERT, a RoBERTa-based encoder family trained from scratch on 49.1~GB of deduplicated Hebrew web text and Wikipedia using a Hebrew-specific byte-level BPE vocabulary. On native Hebrew benchmarks for named entity recognition (BMC, NEMO) and sentiment classification (SMCD), HalleluBERT outperforms monolingual and multilingual baselines, and yields the highest unweighted mean
The continuous evolution of AI, particularly in natural language processing, drives the need for models tailored to specific languages and cultural nuances, making domain-specific breakthroughs increasingly common.
This development indicates a global push to adapt advanced AI technology to diverse linguistic contexts, reducing dependency on models primarily trained on English or widely used languages.
The availability of a robust, Hebrew-specific RoBERTa encoder significantly improves NLP capabilities for Hebrew, opening new avenues for applications and research in that language.
