Meta and Apple Put an 816B Open Model on Two Mac Studios

“The most capable U.S. open model now lives in two Mac Studios on a desk.”

The Story

Muse Spark Open is an 816B-parameter, 42B-active open-weight multimodal model with a one-million-token window, released to run on two M5 Ultra Mac Studios as one machine with a terabyte of unified memory. Meta says on-device agents shipped real Ice Cubes iOS changes and drove DaVinci Resolve frame by frame.

Why It Matters

Two silver boxes in a spare room become a frontier lab. Superintelligence is becoming furniture, with longtime rivals Apple and Meta as unlikely parents.

Caveat

Only worth filming through the physical-object angle; a benchmark recap would be generic launch sludge.
