Implementing A Byte Pair Encoding (BPE) Tokenizer From Scratch
A discussion of the popular byte pair encoding (BPE) tokenization algorithm, which is used in large language models like GPT-2 to GPT-4, Llama 3, etc. to tokenize text. The BPE algorithm was originally described in 1994: “A New Algorithm for Data Compression” by Philip Gage.
