  `gpt-tokenizer` is a Token Byte Pair Encoder/Decoder supporting all OpenAI's models (including GPT-5, GPT-4o, o1, o3, o4, GPT-4.1 and older models like GPT-3.5, GPT-4). It's the [_fastest, smallest and lowest footprint_](#benchmarks) GPT tokenizer available for all JavaScript environments and is written in TypeScript.

  The `gpt-tokenizer` is the **fastest JavaScript BPE Tokenizer Encoder/Decoder** for OpenAI's GPT models (including GPT-5, GPT-4o, o1, o3, o4, GPT-4.1 and older models like GPT-3.5, GPT-4). Written in TypeScript, it's a port of OpenAI's `tiktoken` with additional features, optimized for all JavaScript environments.

  ### Why `gpt-tokenizer` over `tiktoken`?
  While `gpt-tokenizer` is a port of OpenAI's `tiktoken`, it is a **pure JavaScript/TypeScript implementation**, offering superior performance and additional features like `encodeChat` specifically for JavaScript environments, without any C/Rust dependencies.
