Apple and Meta team up to make Muse AI model run on Mac computers
The 816-billion-parameter model is available for download and can run locally on two M5 Ultra Mac Studio computers, Meta said.
- On Thursday, Meta and Apple revealed a collaboration enabling developers to run Muse Spark Open, an 816-billion-parameter open-weight AI model, on high-end Mac Studio computers, marking a rare public partnership.
- Meta AI Chief Alexandr Wang noted that Apple's unified memory architecture allows the M5 Ultra's integrated GPU to utilize up to 512 GB per machine, enabling two Mac Studios to function as one supercomputer.
- Designed for complex software engineering and long-horizon tasks, the model is available under the Muse Model License, which allows free internal use but requires companies earning more than $20 million annually to sign a separate agreement.
- A single Mac Studio with an M5 Ultra chip and 256GB of memory costs at least $10,799, requiring users to pair multiple devices to run the full 816-billion-parameter model locally.
- This alliance signals a strategic shift in Silicon Valley, as Apple seeks to strengthen its AI chip capabilities against Nvidia, while Meta positions Muse Spark Open as the most capable U.S. open-weight model to date.
