Meta Releases Muse Spark Open, an 816B-Parameter Open-Weight AI Model Built to Run on Macs
aiinsider ·
Meta has released Muse Spark Open, an open-weight AI model featuring 816 billion parameters and a one-million-token context window. The company claims this is the most capable open-weight AI model available in the United States based on recent evaluation results. Designed to be natively multimodal, the model supports complex coding tasks and agentic workflows, including bug fixes and video editing operations in DaVinci Resolve. A key feature of Muse Spark Open is its ability to run locally on Apple computers, specifically optimized for Macs with the M5 Ultra chip. However, local execution is resource-intensive, requiring at least one terabyte of RAM. Meta has paired the model with its Muse Code terminal to demonstrate various agentic capabilities. The model is now accessible through several API platforms, offering users greater transparency and flexibility compared to proprietary alternatives.
