Meta's 816B open model now runs on two Mac Studios

First reported Oct 15

Meta released the 816B-parameter Muse Spark Open model on October 15 with downloadable weights under a license with commercial limits. Coverage highlights local running on two M5 Ultra Mac Studios via MLX, availability across multiple clouds, and pricing around $1.25 per million tokens.
