Apple and Meta partner to run Muse AI on Macs
Apple and Meta have announced a strategic collaboration to run Meta's open-weight AI model, Muse Spark Open, locally on Apple's Mac Studio computers, signaling a thaw in their historically tense relationship. This 816-billion-parameter, natively multimodal model features a 1 million token context window, 42 billion active parameters, and is optimized for complex coding and agentic workflows, reportedly outperforming other open-weight models but trailing Chinese models like MiMo-V2.6-Pro. To run at full capacity, the model requires two Mac Studio systems with M5 Ultra chips and 512 GB of unified memory each (1 TB total), but Apple's 512 GB configuration is not yet available, expected at the end of October. Current Mac Studio options max out at 256 GB. Configurations start at $10,799, and the model is also compatible with AMD, Intel, and NVIDIA chips. Available via Hugging Face, Ollama, and cloud platforms, it is restricted by the Muse Model License for large-scale providers.
