Meta 开源 Muse Spark Open:816B 参数编码智能体模型
Meta 发布 Muse Spark Open 的模型权重,这是一个 816B 参数、推理时激活 42.7B 的开源权重全模态 MoE 模型,与 Muse Code 联合训练,面向编码智能体工作流,支持 1M token 上下文和文本、图像、视频、音频输入。它采用压缩 MoE 块和全局/局部混合注意力,在 128K 上下文下把 KV cache 内存降低约 3.7 倍。Baseten 已在其 Model APIs 和 Dedicated Inference 上以 NVFP4 提供该模型,权重体积从约 1.6 TB 降至 540 GB,可运行在单台 4×GB300 节点上。
