This paper challenges the conventional wisdom that language models require subword tokenizers by demonstrating that standard Transformers can effectively process raw byte sequences and outperform traditional models at scale. The research reveals that byte models implicitly develop local abstractions and hierarchical structures without explicit tokenization, with attention naturally concentrating on meaningful segmentation positions.
Background
The paper comes from arxiv (2610.05978v1) and addresses a fundamental question in NLP about whether explicit tokenization is necessary for efficient language modeling, challenging decades of assumption in the field.
