arXiv:2605.30813v1 Announce Type: new Abstract: We propose a novel algorithm for incremental Byte Pair Encoding (BPE) tokenization. The algorithm processes each input byte in worst-case $\mathcal{O}(\log^2 t)$ time, leading to an overall complexity of $\mathcal{O}(n \log^2 t)$, where $n$ is the input length and $t$ is the maximum token length. The algorithm incrementally maintains BPE tokenization results for every prefix of the input text, implementing the standard BPE merge procedure defined by a fixed set of merge rules. This enables efficient partial tokenization in streaming settings. Fun
The paper provides an architectural and theoretical advancement in BPE tokenization, a foundational component for many AI models, aligning with ongoing efforts to improve AI efficiency and scalability.
Efficient incremental tokenization can significantly improve the performance and reduce latency for streaming AI applications, enabling new functionalities and user experiences in areas like real-time conversations or intelligent agents.
The ability to incrementally tokenize input text in real-time with guaranteed worst-case complexity offers a performance advantage for AI systems handling continuous data streams.
