  • Requires around 1TB of RAM to run

A massive model built for the Mac

Meta has introduced Muse Spark Open, a new open-weight AI model designed to run on Mac computers. Open-weight means the model's weights can be downloaded and run on your own hardware.

According to the company, Muse Spark Open is "the most capable US open-weight model to date."

The 1TB RAM requirement

The most striking detail is the hardware demand: running the model requires roughly 1TB of RAM. That is far beyond what a typical laptop or desktop Mac offers, so the model will only be practical on top-end configurations or specialized setups.

This highlights a core obstacle to the spread of open-weight models: the bigger the model, the more expensive the hardware needed to run it locally.

Why it matters

Meta's move reignites competition on the US side of the open-weight race. But the 1TB RAM threshold suggests the model targets enterprises and well-equipped users rather than a broad audience.

Why it matters

A key threshold story for readers curious where open-weight models are heading and how costly local inference hardware has become.
