Meta 发布 816B 参数开源权重模型 Muse Spark Open,支持 1M 上下文窗口
Meta 发布 Muse Spark Open 的模型权重,这是一个 816B 参数的开源权重模型,激活参数 42B,上下文窗口为 100 万 token,面向编码、软件工程和多步推理。模型原生多模态并支持智能体工作流,可通过 Baseten、Fireworks AI、Groq、OpenRouter 等推理平台使用,权重可从 Hugging Face、Amazon SageMaker AI、Google Cloud Model Garden 和 Microsoft Foundry Models 下载。Meta 称其针对两台搭载 M5 Ultra 芯片的 Apple Mac Studio 做了本地运行优化,并展示了用 Muse Code 修 bug、加功能和构建 iOS 应用等端侧工作流。
rk Open includes custom GPU kernels optimised for inference through SGLang. Meta said the kernels delivered speedups ranging from 1.03 times to 3.95 times in kernel-level tests on NVIDIA and AMD GPUs. The company also reported a 3% end-to-end performance improvement on AMD MI350 GPUs. The model supports several hardware platforms, including AMD, Apple, Intel and NVIDIA silicon. Developers can further fine-tune it using PyTorch's TorchTitan framework. Meta has released the weights under its Muse
