Apple and Meta team up to bring open-weight Muse Spark Open to Macs

–

Neutral summary

Meta released Muse Spark Open on October 15, an open-weight multimodal model the company describes as the most capable US open-weight model to date. The model has 816 billion parameters, of which 42 billion are active, uses a Mixture of Experts architecture, and processes text, images, video, and audio with up to one million tokens of context. It is optimized to run locally on two Mac Studio computers with M5 Ultra chips, requiring around 1TB of RAM. The release is the result of collaboration between Meta and Apple, companies whose leaders have spent years clashing over privacy and the future of computing. Meta's AI chief Alexandr Wang told Axios: “We're excited for mommy and daddy to be playing nice again.” Meta CEO Mark Zuckerberg thanked Apple CEO John Ternus on X, and Ternus replied with praise for the team. Meta says the model performs roughly on par with leading open-weight Chinese models such as Alibaba's Qwen, Moonshot AI's Kimi K3, and Z.ai's GLM, and is positioned to compete with them. Several outlets note the partnership marks a striking détente between two Silicon Valley giants.
