**TLDR:** A tokenization method that builds a data-driven subword vocabulary by learning frequent subunit merges.

<p>Byte Pair Encoding is one of the most widely known subword tokenization methods. It starts from small units and gradually merges the most frequent co-occurring pieces. This allows it to build an efficient vocabulary while still keeping rare words decomposable. It offers a strong practical balance, especially in generative language models and open-ended text systems.</p>
