Understanding Tokenization in LLMs: Why Models Struggle with Word Reversal
- LLMs struggle with word reversal because they process text as tokens rather than individual characters.
- Tokenization, done by OpenAI's tokenizer Tiktoken, breaks text into tokens based on patterns and training data.
- Tokenization is biased towards certain languages and domains, resulting in a 'tokenization penalty' for non-English content.
- Understanding tokenization is essential for efficient token management and cost control in AI applications.
