Meta Muse Spark Open: 816B Open-Weight Model Built for Macs

IntelliTechs ยท Oct 15, 2026

What this means for you

You can download the weights today, but running the full model at home takes about 1TB of memory, which means two top-spec Mac Studios.

What does "open-weight" mean?

An open-weight model is one whose "weights," the numbers training adjusts to store what the AI learned, are available to download.

What can it do?

Muse Spark Open is natively multimodal, meaning it was built from the start to handle more than one kind of input, such as text and images.

Why the Mac Studio, and what does it cost?

The reason is the unified memory in Apple silicon, which the CPU and GPU share.

Can you use it without that hardware?

Yes, through an API. TechCrunch reports the model is already available on several API platforms, without naming them, and you pay per use rather than buying the machines.

The Apple and Meta backstory

The partnership stands out given the two companies' history of friction.
