Researchers have developed a new method called Mediator for merging Large Language Models (LLMs) more efficiently. This technique addresses the performance degradation caused by parameter conflicts in traditional averaging methods. Mediator selectively averages layers with minimal conflicts and employs task-level expert routing for layers with significant conflicts, while also decoupling experts to reduce storage costs. The approach further incorporates task uncertainty to select and merge appropriate experts for out-of-distribution samples, demonstrating performance improvements on LLaMA and Qwen models with reduced system costs.
