Surprise! Meta and Apple Worked Together on a New Open-Source AI Model
The companies said the open-weight model can run on two to four linked Mac Studios and released the trained files for public download.
- On Thursday, October 15, 2026, Meta and Apple released Muse Spark Open, an open-weight AI model designed to run locally on Mac Studio desktops with two connected machines.
- This partnership marks the first public collaboration since around 2017, following years of friction over Apple's app store policies and privacy changes that hurt Meta's ad business.
- Meta Chief AI Officer Alexandr Wang noted the 816 billion parameter model utilizes Apple's MLX framework, allowing two M5 Ultra Mac Studios to, as Meta wrote, "behave like one supercomputer."
- By releasing the model as open-weight, Meta aims to provide a U.S.-based alternative to Chinese offerings and closed systems from frontier labs Anthropic and OpenAI.
- Although Meta CEO Mark Zuckerberg and Apple CEO John Ternus declined to confirm a broader relationship, the collaboration could reshape where serious AI work runs.
