混合专家模型:LLM 路由器如何选择和激活稀疏网络

大型语言模型中的混合专家(MoE)架构,以 Mixtral 8x7B 和 Nemotron 3 Ultra 550B-A55B 等模型为例,用多个较小的专家网络取代了密集的前馈网络(FFN)层。当处理一个 token 时,路由器层会确定哪些专家最相关,通常会选择前两个。这种稀疏激活显著降低了每个 token 的计算成本,因为只有选定的专家执行计算,而总参数量可以高得多。尽管由于需要存储所有专家,VRAM 需求保持不变,但每个 token 的 FLOPs 减少了,从而提高了推理效率。 AI

影响 解释了 MoE 模型的计算效率提升和架构细节,影响推理优化。
