New method enables auditable access control for sparse MoE language models

Researchers have developed a novel method called Policy-Masked Private Experts (PMPE) to control access to specific parameters within sparse Mixture-of-Experts (MoE) language models. This technique allows for auditable and reversible access control, ensuring that unauthorized requests cannot execute private expert parameters. Experiments on models like Qwen3-30B-A3B and DeepSeek-V2-Lite demonstrated that PMPE effectively prevents unauthorized access while maintaining the utility of the private experts for authorized use, showing significant improvements in tool use and overall performance.
