Meta launches an open-weight AI model that runs on Macs

Meta and Apple have partnered to launch Muse Spark Open, a new open-weight AI model designed to run locally on Macs using Apple silicon. The release highlights tighter alignment between Meta’s AI model strategy and Apple’s on-device computing ecosystem.

The launch reflects growing momentum behind local AI, where models run directly on consumer hardware rather than relying solely on cloud infrastructure. For Apple, support from major model developers could strengthen the Mac’s role as a platform for privacy-conscious and developer-friendly AI applications.
