Nemotron-3-Super-120B-A12B 采用 Mamba+MoE 架构实现 504K token 召回

NVIDIA 的 Nemotron-3-Super-120B-A12B 模型,一种混合 Mamba 和 Mixture-of-Experts 架构,已展示出高达 504,000 token 的完美召回能力。与传统的 KV 缓存方法相比,该模型利用 Mamba 层来维持恒定的循环状态,显著降低了长上下文相关的计算成本。该模型在拥有约 71GB 显存的四块 3090 GPU 上运行,在扩展上下文长度时实现了令人印象深刻的解码速度,性能优于同类全注意力模型。 AI

影响 展示了基于 Mamba 的架构在大语言模型中高效处理长上下文的潜力。
