## Items

- [AutoTokenizer (Hugging Face Transformers)](https://vectordb.ever.works/items/autotokenizer-hugging-face-transformers) — A utility class from the Hugging Face Transformers library that automatically loads the correct tokenizer for a given pre-trained model. It is crucial for consistent text preprocessing and tokenization, a vital step before generating embeddings for vector database storage.
- [tiktoken](https://vectordb.ever.works/items/tiktoken) — OpenAI's tokenizer library for encoding and decoding text into tokens, primarily used for calculating token counts with OpenAI's models and estimating chunk sizes for vector database document processing.
- [Hugging Face Tokenizers](https://vectordb.ever.works/items/hugging-face-tokenizers) — A library from Hugging Face providing fast and customizable tokenization, a fundamental step for preparing text data for embedding models used with vector databases.
