Meta releases Muse Spark Open, an 816B-parameter open AI model tuned to run locally on Mac Studio

Meta introduced Muse Spark Open, an open model listed on Hugging Face as an 816B-parameter system with 42B active parameters. The company says the model is built for developers and optimized for local use on high-end Apple hardware such as Mac Studio.

The release signals continued momentum toward local AI that can run on powerful consumer or prosumer machines rather than only in cloud data centers. By targeting Mac Studio, Meta is positioning open models for creators and developers who want more control over latency, privacy, and deployment costs.
