Researchers have developed SafeStart, a new method to mitigate safety risks associated with optimizing Mixture-of-Experts (MoE) language models for faster serving. While reducing the number of experts used per token can significantly speed up model inference, it can also lead to a decrease in the model's ability to refuse harmful requests. SafeStart addresses this by running all experts for the initial prompt and the first few generated tokens, then reverting to the reduced expert set. This approach largely restores the model's refusal capabilities while retaining most of the speedup, demonstrating that efficiency gains in MoE serving do not necessarily have to come at the cost of safety.
