Meta Releases Muse Spark Open, Bringing 816B-Parameter AI Model to Macs via Apple Partnership

Meta and Apple have announced a rare strategic partnership to enable developers to run Meta's largest open-weight AI model directly on Apple's consumer hardware. The collaboration brings Muse Spark Open, an 816-billion-parameter multimodal model with a 1-million-token context window, to Apple silicon through optimizations with the MLX framework, marking the first time a frontier-scale open-weight model can run locally on standard developer hardware without cloud reliance.
