Meta and Apple collaborate to launch Muse Spark Open AI model for Macs
Meta and Apple announced a partnership today to release the Muse Spark Open AI model, which runs locally on new Mac Studio computers.

Model specifications and capabilities
The new Muse Spark Open model contains 816 billion parameters and supports a context window of one million tokens. Meta describes the system as natively multimodal and capable of handling complex software engineering tasks. The company states this is the most capable open-weight model currently available in the United States.
Hardware requirements for local use
Running the model locally requires at least one terabyte of RAM according to Engadget. Performance is optimized on Mac Studio machines equipped with the M5 Ultra chip. Users can execute the software directly from their desktop using the latest MLX framework.
Corporate collaboration details
Meta CEO Mark Zuckerberg and Apple CEO John Ternus publicly supported each other during the launch event. The two companies have been working together for several months to integrate these technologies. This cooperation allows the model to run efficiently on Apple silicon hardware.
