Meta introduces Muse Spark Open for Apple desktops

Meta has released Muse Spark Open, an artificial intelligence model that runs on Apple's Mac Studio computers. This collaboration between the two tech giants allows developers to download the model's weights, rather than relying solely on remote services. The 816 billion parameter system can operate locally on two Mac Studios with M5 Ultra processors.

It has a context window of one million tokens and is designed for complex software engineering, coding assistance, and autonomous tasks requiring multiple reasoning stages. Meta's chief executive, Mark Zuckerberg, acknowledged Apple's contribution to the model's optimization, while Apple's John Ternus appreciated the potential for running large-scale models on desktop hardware.

The model uses a mixture-of-experts architecture to reduce computing demands, but its high memory requirements limit accessibility to many individual users. Meta has also made the model available through hosted APIs for developers without the necessary hardware.
