About this paper

David Nordfors

The Metanym Game creates a benchmark where models write slot-based descriptions meant to remain true across domains, then judge one another’s work. Making claims checkable sentence by sentence lets the system score work without an external answer key. Its score correlates with G-P-Q-A accuracy across 12 models (Pearson r = 0.98), but this does not show the tests measure the same mechanism.
