Meta Partners With Apple to Run New Muse Spark AI Model on Macs

Meta Platforms and Apple have partnered to enable Meta's new open-weight AI model, Muse Spark Open, to run natively on high-end Mac desktop computers, marking their first public collaboration since 2017. Launched on October 15, 2026, the 816-billion-parameter model features 42 billion active parameters and a 1-million-token context window designed for coding and agentic tasks. Running the model locally requires pairing two to four Mac Studio workstations equipped with M5 Ultra processors and at least 256GB of memory each, with system prices starting at $10,799 per machine.
