A new research paper analyzes the gap between a student AI model's ability to mimic a teacher model and its actual performance on a task. The study uses a minimal three-party model to demonstrate that while the student's mimicry error remains constant, its error on the true task increases with the teacher's misspecification. This suggests that relying solely on mimicry metrics can be misleading, and a specific gap metric is needed to distinguish true task failure from capacity limitations. AI
