FAQPage Schema

How do I train a custom tokenizer on a large corpus using BPE or WordPiece?▼

To train a custom tokenizer, use the flexible trainers to generate BPE, WordPiece, or Unigram vocabularies from your text corpus. This produces a fast, Rust-based tokenizer optimized for high-throughput NLP pipelines.

What is the fastest way to tokenize text for production NLP pipelines?▼

The fastest way to tokenize text is using Rust-based tokenizers, which provide high-throughput text processing and alignment tracking. This ensures deterministic behavior suitable for production-scale NLP deployments.

Can I use a custom trained tokenizer with HuggingFace Transformers?▼

Yes, you can use a custom trained tokenizer with HuggingFace Transformers through seamless PreTrainedTokenizerFast and AutoTokenizer integration. This wire your custom vocabulary directly into Transformers workflows for fast inference.

Does Rust-based tokenization support alignment tracking for downstream tasks?▼

Yes, Rust-based tokenization supports alignment tracking for downstream tasks. The tokenizers map generated tokens back to original text spans, enabling precise alignment mapping across large corpora during processing.

When should I train an Unigram tokenizer instead of BPE for my NLP model?▼

Train an Unigram tokenizer instead of BPE when your NLP model requires probabilistic vocabulary generation over byte-pair merging. The flexible trainers support both algorithms, allowing you to choose based on your specific corpus characteristics.
