Meta Unveils Muse Spark Open, a Heavyweight AI for Mac Hardware

Meta has introduced Muse Spark Open, an open-weight AI model packing 816 billion parameters and a 1-million-token context window. Designed specifically for complex coding and agentic tasks, the model aims to bring high-end performance to local Apple hardware, provided the user can supply the necessary 1 terabyte of RAM.

The model represents a significant shift in local AI deployment, functioning best on a Mac Studio equipped with the M5 Ultra chip. Meta demonstrated the system's utility by pairing it with the Muse Code terminal to execute automated bug fixes and build updates for a Mastodon client. Beyond software development, the AI proved capable of handling creative workflows, including reviewing and cropping footage within DaVinci Resolve.

By releasing Muse Spark Open as an open-weight model, Meta offers developers a transparent alternative to proprietary systems. This architecture avoids the black-box limitations of closed models while maintaining cost-efficiency for large-scale agentic labor. The company has made the model available immediately through various API platforms for those seeking to integrate it into their own technical environments.
