Meta releases Muse Spark Open, a new open-weight AI model

Meta has launched Muse Spark Open, an open-weight model that it says rivals and in some cases outperforms leading Chinese open-weight models. Developers can download and modify its weights, and Meta says the model is optimized for Apple's M5 Ultra chips. Running it requires two Mac Studios with M5 Ultra chips, which Meta describes as a personal supercomputer.
