Meta launches Muse Spark Open: open-weight model running locally on Apple silicon
Meta and Apple are shipping Muse Spark Open as an on-device model for Macs. The inversion shifts cognition toward users while the old platforms remain the gatekeepers.
SO WHAT — This looks like a window where local intelligence is still a negotiable choice, but distribution hinges on who controls model access and updates.

Meta launches Muse Spark Open, staking on open-weight reasoning
Meta claims Muse Spark Open improves multi-step reasoning and software engineering versus Chinese competitors. The inversion is shifting creation toward a few model owners, while others consume and adapt the output.
SO WHAT — In the thousand-day window, open-weight claims can widen choice—if distribution holds—otherwise the old system just re-schedules access through a new interface.
