## Summary

Meta announced Muse Spark Open, a natively multimodal AI model with 816 billion total parameters. The company says it is the most capable US open-weight model to date and the first in its class to run on a desktop using two Apple M5 Ultra Mac Studios with the latest MLX framework.

According to The Verge, Meta and Apple collaborated for several months on the launch and are now publicly supporting each other’s work. Apple published a technical post about MLX, a framework for machine-learning tasks on Apple Silicon, and also mentioned Muse Spark Open and two other open models.

## Why it matters (editorial interpretation)

The reported collaboration could increase interest in running large open-weight models locally on Apple hardware, although the capability claim comes from Meta and the summary provides no performance or availability details.
