Overview
Tiktoken is a BPE (Byte Pair Encoding) tokenizer designed for OpenAI's language models, enabling efficient text processing by converting raw text into tokens. It provides APIs to calculate token counts and manage text segmentation, crucial for optimizing input length in LLM interactions. The package supports multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, making it suitable for cross-platform applications that integrate with OpenAI models. Built with Dart, it ensures consistent tokenization across environments.
