Meta and Apple team up to make Muse Spark Open AI model run better on Macs

Meta announced the Muse Spark Open AI model, which it calls the most capable US open-weight model to date and the first in its class able to run on a desktop using two Apple M5 Ultra Mac Studios with the latest MLX framework. The 816-billion-parameter natively multimodal model is aimed at long-horizon tasks, complex software engineering, and multi-step reasoning, and Meta and Apple worked together on the launch, with Mark Zuckerberg and new Apple CEO John Ternus publicly praising each other. Apple also published a technical post about MLX, Muse Spark Open, and two other open models.
