Meta and Apple run 816 billion parameter AI model on two Mac Studios
What happened
Meta and Apple collaborated to run Muse Spark Open, an 816 billion parameter open-weight AI model, locally on two M5 Ultra Mac Studios. Meta launched its Muse personal AI agent on September 8, 2026, roughly five weeks before Spark Open. The agent performs tasks across native macOS apps.
Why it matters
Running a model this large on desktop machines shows that frontier-scale AI can run on your own hardware instead of a cloud service. For businesses, this means keeping data private and avoiding per-use API fees. The catch is that two top-tier Mac Studios are a professional investment, not a casual purchase for a laptop owner.
Who's doing it
Meta is reinforcing its bet on open weights, letting anyone take the model and run it themselves. Apple provided the hardware partnership, demonstrating the Mac Studio as a platform for large local AI.
Try it
- Visit Meta's open model page and search for Muse Spark Open to see if a smaller version is available for your hardware.
- Download an open-weight model manager like Ollama or LM Studio to your Mac or PC.
- Pick a smaller open model such as Llama 3.2 and run it locally to experience how on-device AI works without sending data to the cloud.

The Boss hype translator
Love the synergy here. Meta and Apple are democratizing frontier AI by letting you run 816 billion parameters locally, which honestly means two top-tier Mac Studios cost more than my first car.
The Yinzer
Eight hundred billion parameters on two Mac Studios, big whoop. Yinz think I got that kind of money? I could redd up half of dahntahn for what them machines cost, n'at.
Karen what's the catch
So Meta's agent can do tasks across my NATIVE macOS apps? WHO decided my calendar and mail are fair game for a Facebook company's AI? What are they scraping from my laptop?
The Professor fact check
The article specifies the model ran on M5 Ultra chips, not the M-series chips currently in consumer Macs. The Muse personal agent launched September 8, 2026, roughly five weeks before Spark Open. Worth distinguishing.
