Can I train a custom tokenizer from my own dataset?

Yes, the skill provides patterns for training BPE, WordPiece, and Unigram models from scratch using your own text files or dataset iterators.

What is alignment tracking and why is it useful?

Alignment tracking records the start and end character positions of every token in the original text. This is critical for tasks like Named Entity Recognition (NER) or question answering where you must map model outputs back to the source document.

How much faster is this than standard Python tokenizers?

Because it is implemented in Rust, it is typically 10 to 100 times faster than pure Python implementations, processing 1GB of text in less than 20 seconds.

Does this skill work with the Transformers library?

Absolutely. It supports loading pretrained tokenizers directly from the HuggingFace Hub and converting custom trained tokenizers into Transformers-compatible formats.
