How does Cursor's tab completion differ from other AI completions?

Cursor's tab completion is a multi-line, context-aware completion that can fill in entire code blocks, not just single-line suggestions. It also uses a "next edit" prediction — after you make one change, Cursor predicts where your next edit will be and pre-fills it. This makes Cursor feel much faster for refactoring tasks where you're making consistent changes across a file.
