This research paper, "How much do language models memorize?" by Morris et al. (2025), introduces a novel method to estimate the extent of information a model retains about specific data points. The authors formally distinguish between "unintended memorization" (information about a specific dataset) and "generalization" (information about the true data-generation process). By focusing on unintended memorization, they estimate the capacity of language models, finding that models in the GPT family have an approximate capacity of 3.6 bits-per-parameter.
