Meta launches an open-weight AI model that runs on Macs

Open-weight models publish their internal settings, so anyone can download and run them instead of only using the maker's app. Meta says its new Muse Spark Open, an 816 billion parameter model that is natively multimodal, is the most capable open model from the US. Running it on a Mac locally needs at least a terabyte of RAM, best on a new Mac Studio.
