Researchers have developed a new technique called Norm-Anchor Scaling (NAS) to improve the longevity of model edits in large language models. Existing methods for sequential model editing can degrade performance over time due to a feedback loop that amplifies norm growth. NAS addresses this by rescaling edited value vectors to a reference norm, effectively breaking the loop. Experiments show NAS extends the usable editing horizon by over four times and improves long-term editing performance by an average of 72.2% without significantly impacting single-edit accuracy or computational cost.
