A clean three-panel comparison of tokenization schemes for the word "unbreakable". Left panel: Whole-word tokenization — "unbreakable" as one big blue block labeled "1 token (unknown to model if not in vocab)". Middle panel: Character tokenization — "u n b r e a k a b l e" as 11 tiny red blocks labeled "11 tokens (inefficient)". Right panel: Subword tokenization — "un" as green block, "break" as yellow block, "able" as blue block, labeled "3 tokens (efficient, composable)". Title: "Three Ways to Split 'unbreakable'". Minimal, textbook-style diagram.
