Meta open-sources 816B multimodal MoE model Muse Spark Open
What happened
2026年10月15日，Meta在Hugging Face Blog发布开源权重模型Muse Spark Open，采用MoE架构，总参数约816B、每token激活约42B，支持文本、图像、音频和视频输入，上下文窗口最高100万token。10月16日，AWS Machine Learning Blog报道该模型已在Amazon SageMaker JumpStart上线，同样支持100万token上下文窗口，采用MoE架构，总参数816B、每token激活42B，可接收文本、图像、文档、音频和音视频输入并输出文本。同日The Decoder报道称其为美国最强开源权重模型，面向编码与智能体任务，拥有8160亿参数（激活420亿）、最高100万token上下文，支持文本、图像、视频和音频。TechCrunch同日报道称，Meta发布可在Mac本地运行的开放权重模型Muse Spark Open，称其为美国“最强”开放权重模型，拥有8160亿参数和100万token上下文窗口，原生多模态，面向复杂编码任务和智能体工作。The Verge同日报道称，Meta与Apple合作让该模型在Mac上运行更佳，称其是迄今能力最强的美国开源权重模型，也是同类中首个能在桌面端运行、需两台搭载最新MLX框架的Apple M5 Ultra Mac Studio的模型。

- TechCrunch · AIMeta launches an open-weight AI model that runs on Macs
Meta and Apple have teamed up for the launch of the social media giant's newest model, Muse Spark Open, which will run locally on Apple silicon.
- The DecoderSelectedMuse Spark Open is Meta's answer to Qwen, GLM, and Kimi in the open-weight race
Meta's Muse Spark Open is a new open-weight model with 816 billion parameters that processes text, images, video, and audio with up to one million tokens of context. It performs roughly on par with the most capable open-weight Chinese AI models on benchmarks and is optimized to run locally on Apple's M5 Ultra.
- The Verge · AISelectedMeta and Apple team up to make Muse AI models run better on Macs
Meta announced the Muse Spark Open AI model today, claiming that it's the "most capable US open-weight model to date." But the company also says that it's the "the first model in its class" that can "run on your desktop using two Apple M5 Ultra Mac Studios with the latest MLX framework."
- AWS Machine Learning BlogSelectedMeta’s Muse Spark Open now available in Amazon SageMaker JumpStart
Muse Spark Open, Meta's coding-optimized open-weight model, is now available in Amazon SageMaker JumpStart. Deploy it to a SageMaker AI endpoint in your own AWS account using SageMaker Studio or the SageMaker Python SDK, and run your first inference request.
- Hugging Face BlogSelectedWelcome Muse Spark Open: open-weight frontier multimodal mixture-of-experts model from Meta
Muse Spark Open is an open-weight model from Meta. The mixture of experts model brings text, images, audio, and video into a model with approximately 816 billion parameters, around 42 billion active per token, and a context window of up to one million tokens.
