  "summary": "Meta has launched Muse Spark Open, an open-weight AI model that the company claims is the most capable U.S. open-weight model to date. According to Punch Nigeria, the model is optimized to run on Apple’s M5 Ultra chips and rivals top Chinese developers. Slashdot and MacRumors report that the model features 816 billion total parameters with 42 billion active parameters and includes a 1 million-token context window. Meta states the model is designed for software engineering, agentic work, and multi-step reasoning.\n\nThe model is designed to run locally on a desktop using two 512GB M5 Ultra Mac Studios via Apple’s MLX framework. Slashdot notes that Apple's unified memory architecture allows the integrated GPU to use up to 512 GB per Mac Studio, enabling two machines to hold the entire model and act like a single supercomputer. The Verge reports that Meta and Apple collaborated on the launch, noting public support between Meta CEO Mark Zuckerberg and Apple CEO John Ternus regarding the model's efficiency on Mac Studio hardware.",
