Demystifying Tokenization: The First Step in Building LLMs

Ever wondered how large language models (LLMs) like GPT-4 understand text? Well, they don’t—at least, not like humans do! Instead, they break text down into tokens, the fundamental building blocks of all AI-generated language.

In this blog, I’ll dive deep into tokenization, the first and most crucial step in the LLM pipeline. From Byte Pair Encoding (BPE) to WordPiece, I’ll cover the why, how, and what of tokenizers—so you can truly grasp how LLMs process text, one token at a time.
