Researchers have developed a novel three-layer architecture designed to enhance privacy in personalized large language models. This system separates user-specific data from the core model weights by utilizing composable adapters and deletable user proxies. Experiments on Phi-3.5-mini and Llama-3.1-8B demonstrated that user data influences outputs without contaminating shared weights, and that removing user proxies effectively reverts the model to its baseline state.
