Meta Releases Muse Spark Open Model in Collaboration with Apple to Run on Mac Studio
Meta has launched Muse Spark Open, an open-weight AI model optimized alongside Apple to run locally on M5 Ultra-powered Mac Studio systems without cloud reliance.

Meta Launches New Large-Scale AI Model
Meta has officially announced the launch of its new large-scale AI model, Muse Spark Open. Released as an open-weight model, it is designed to tackle complex technical and agentic workflows.
Collaboration with Apple for Local Execution
In a notable move, Meta partnered with Apple to optimize Muse Spark Open to run locally on Mac Studio workstations equipped with Apple's M5 Ultra chip. This optimization allows the model to perform local inference directly on the hardware, eliminating the need to rely on external cloud infrastructure.
Key Specifications and Architecture
The Muse Spark Open model includes several key technical specifications:
- Total Parameters: Features an 816 billion (816B) parameter architecture.
- Active Parameters: Operates using 42 billion (42B) active parameters during inference.
- Context Window: Supports a context window of up to 1 million tokens.
- Target Tasks: Built specifically to handle coding and autonomous agentic tasks.
Why This Development Matters
This rare collaboration between two major technology rivals signals a strategic shift toward running heavy AI models locally. By conducting inference on-device rather than in the cloud, teams can lower their infrastructure expenses while keeping internal and sensitive codebases secure within local hardware boundaries.
Who Should Pay Attention
This release is particularly relevant for:
- Software developers
- AI engineers
- Technology enterprises seeking to run top-tier models on their own hardware
