Meta's developer lineup now highlights Muse Spark 1.2 for coding and Muse Glimmer for local agent work. Glimmer is a 30-billion-parameter model intended to run on a Mac or PC with a suitable consumer GPU.

A local model can keep more data on the device and avoid per-call cloud charges. It also shifts responsibility to the user for hardware, setup, updates and security.

Developers should read the exact license before using any open model commercially. Model weights may be downloadable without granting every right associated with traditional open-source software.

What this means

  • Muse Spark 1.2 is optimized for coding.
  • Muse Glimmer targets local, always-on agents.
  • Hardware and license terms affect the real cost of local AI.
