tokenizer

Breaks words apart

A tokenizer is software that breaks text into smaller units called tokens—words, subwords, or characters—for processing by a computer program.

In natural language processing and large language models, tokenization is the essential first step: The tokenizer split "unhappiness" into three tokens.

Different tokenizers use different strategies, affecting how efficiently a model handles various languages and vocabulary.
