Meta and Apple team up to make Muse AI models run better on Macs

4 sources →

Meta and Apple have announced a collaboration to optimize Meta's new Muse Spark Open AI model for Apple Silicon. The 816-billion-parameter model is designed to run locally on high-end Mac Studio machines using Apple's MLX framework, marking a significant shift in the historically contentious relationship between the two tech giants. While the model is open-weight and accessible via Hugging Face, running it requires substantial hardware investment, typically involving two to four Mac Studio units equipped with M5 Ultra chips and up to 1TB of unified memory.
