LLM Tokenization Explained: From Text to Numbers for AI Models

Large Language Models (LLMs) require text to be converted into numerical representations called tokens before processing. A token can be a word, part of a word, or punctuation, and each is assigned a unique Token ID. Different LLMs use distinct tokenizers, leading to varied Token IDs for the same text. Algorithms like Byte-Pair Encoding (BPE), Byte-level BPE (BBPE), and WordPiece are employed to manage vocabulary size and sequence length, addressing issues like out-of-vocabulary words and long sequences inherent in character-level tokenization. The number of tokens processed directly impacts the model's context window and computational requirements. AI
