Researchers have introduced SEAL, a novel training-time defense mechanism designed to enhance the global safety of Mixture-of-Experts (MoE) large language models. MoE architectures, which activate only a subset of expert modules per token, are powerful but susceptible to adversarial attacks that manipulate expert activation. SEAL leverages the 'shared expert' component, an always-activated part of Hybrid MoE models, to act as a router-independent anchor for safety. This approach aims to mitigate vulnerabilities introduced by sparse routing and has demonstrated a reduction in attack success rates by up to 60% with minimal impact on model capabilities. AI
IMPACT Introduces a new method to improve the security and robustness of MoE models against adversarial attacks.
