Meta and Apple Bring Muse Spark Open AI Model to Mac Studio

Meta today announced the release of Muse Spark Open, which it says is the "most capable U.S. open-weight model to date."


‌Meta‌ worked with Apple to bring Muse Spark Open to the Mac, and the model can run on a desktop setup with two 512GB Apple M5 Ultra Mac Studios running the latest MLX framework. ‌Meta‌ CEO Mark Zuckerberg thanked Apple CEO John Ternus for working with Meta.

@finkd Congrats to the team! Amazing to run a model of Muse Spark Open's caliber and scale this efficiently, right from your desk. Mac Studio keeps pushing the boundaries of on-device AI!

— John Ternus (@johnternus) October 15, 2026


Muse Spark Open has 816 billion total parameters with 42 billion active parameters and a 1 million-token context window. It is meant for coding and agentic work, and ‌Meta‌ says it excels at extended tasks, multi-step reasoning, and software engineering.

The new Muse model was tuned to run on Mac Studio, and ‌Meta‌ says the ‌Mac Studio‌ paired with Muse Spark Open is the "best way to run a powerful model on your own desktop." From ‌Meta‌:
Apple's unified memory architecture lets the M5 Ultra's integrated GPU use up to 512 GB per Mac Studio, so two machines can hold an entire model. And the chip's 1.2 TB/s of memory bandwidth is fast enough to read the small slice each token needs. The result is two Mac Studios behave like one supercomputer with a terabyte of unified memory.

Apple hasn't released the 512GB ‌Mac Studio‌ as of yet, but it's supposed to be coming later this month. It won't be cheap, because the 256GB ‌Mac Studio‌ is already priced over $10,000.

The model is available through API platforms at Baseten, Fireworks AI, Groq, Modal, Nebius, OpenRouter, and Together AI, with model weights downloadable from Amazon SageMaker AI, Google Cloud Model Garden, Hugging Face, and Microsoft Foundry Models. Muse Spark Open is free to download and has a license allowing limited commercial use.

Apple and ‌Meta‌ often argue more than they work together, so it is something of a surprise to see the two companies partnering for Muse Spark Open. "We're excited for mommy and daddy to be playing nice again," ‌Meta‌'s AI chief Alexandr Wang told Axios.

Apple CEO John Ternus on Early Foldables: 'Kind of Cheap and Crappy'

In a recent interview with TIME, Apple CEO John Ternus described some early foldable smartphones as feeling "kind of cheap and crappy." Samsung released its first foldable in 2019, but Apple opted to take its time and has now developed the iPhone Duo with a premium design and a barely-noticeable display crease.

The interview touches on how Ternus gave Apple's design team "the confidence to really push the boundaries on innovation and manufacturing" with the iPhone Duo, which is available to pre-order starting this Friday at 5 a.m. Pacific Time.

Greg Joswiak Says Apple Isn't Focused on Making AI for 'Lunatic Fringe'

In an interview with TIME's Andrew R. Chow, Apple's marketing chief Greg Joswiak said Apple Intelligence is meant for "everyday people" as opposed to the "lunatic fringe."


The full sentence: "In the midst of a populist AI backlash, they contend that they are building a modest but personalized and privacy-preserving form of AI that will actually help ordinary people as opposed to merely dazzling Silicon Valley's 'lunatic fringe,' as Greg Joswiak, senior vice president of worldwide marketing, puts it."

Joswiak apparently believes Apple Intelligence is not for "die-hard AI believers chasing superintelligence," as Chow described it.

"We love them, and they can use it too, but that's not our target," said Joswiak. "It's how to make it better for everyday people."

Joswiak added that "we don't feel threatened" in regards to Apple facing competition in the AI industry. "The fact that we can do the integration that we can means we can create just a better experience than anybody else," he said.
