Superword tokenization algorithms achieve over 600x speedup

Researchers have developed significantly faster implementations of the BoundlessBPE and SuperBPE algorithms for tokenization, which extend Byte Pair Encoding (BPE) to create "superwords" that combine multiple pretokens. Previous versions were impractically slow, taking days to train on small datasets. The new methods aggregate supermerge candidates by frequency, avoiding the need to load entire documents into memory and achieving speedups of over 600x, reducing training time to minutes. Both Python and Rust implementations are now open-sourced. AI

IMPACT Faster tokenization methods could lead to more efficient training and inference for large language models.
