Overview

• Research proves tokenization for language models is NP-Complete
• Finding optimal tokenization requires examining all possible combinations
• Current approaches use approximations and heuristics
• Paper demonstrates theoretical limits of tokenization algorithms
• Results impact how we develop and optimize language models

Plain English Explanation

Tokenization splits text into smaller pieces that language models can process. This paper proves that finding the perfect way to split text is extremely difficult - so difficult that even computers can't solve it efficiently.

Think of tokenization like trying to cut a long str...
