BYTE PAIR ENCODING

Understanding Byte Pair Encoding (BPE) by Building It From Scratch Introduction: Why Tokenization Exists When working with Large Language Models (LLMs) like GPT, LLaMA, or Mistral, one of the first hidden steps is tokenization. LLMs do not read raw text. Instead, text must first be converted into tokens — numerical representations that the model can process. One of the most important tokenization techniques used in modern NLP systems is Byte Pair Encoding (BPE). In this article,...
