Meta released Muse Spark Open, an open-weight model with 816 billion total parameters, 42 billion active parameters, and a 1 million-token context window, designed for coding and multi-step agentic tasks. The model is optimized to run locally across two Mac Studios equipped with 512GB M5 Ultra chips using Apple's MLX framework, which Meta calls the best desktop setup for running a powerful model. Apple has not yet released the 512GB Mac Studio, though it is expected later this month.

A new open-weight AI model, Muse Spark Open, has been released and optimized to run on Mac Studio machines with Apple's M5 Ultra chip, reportedly allowing two linked Macs to function like a single machine with a terabyte of unified memory. The release also includes custom Helion GPU kernels in SGLang that the developers say speed up performance on NVIDIA and AMD hardware, and the model underwent additional safety post-training evaluated against an internal scaling framework before release.

Meta has open-sourced Muse Spark Open, an 800-billion-parameter model it calls the most capable US open-weight model yet. Running it locally requires roughly 1TB of unified memory, achievable by pairing two of Apple's upcoming M5 Ultra Mac Studios with 512GB each, or four 256GB units costing about $38,000. The weights are now downloadable from Hugging Face, and Meta says the model was built in collaboration with Apple to run on its new hardware.

Apple has maintained the same 7.7-inch aluminum enclosure for the Mac Studio since its 2022 launch, now in its fourth hardware generation with the M5 Ultra. Internally, capabilities have grown sharply: the original M1 Ultra topped out at 128GB of memory, while the new M5 Ultra supports up to 512GB with data transfer speeds of 1.2TB/s, about 50 percent faster than the M3 Ultra.
