Understanding whether and to what extent large language models (LLMs) have memorised training data has important implications for the reliability of their output and the privacy of their training data.

Our knowledge estimator is both conceptually simpler (i. e., doesn't depend on meta-linguistic judgments of LLMs) and easier to apply (i. e., is not LLM-specific), and we demonstrate that it can surface more of the latent knowledge embedded in LLMs.
