Meta Releases 30-Billion-Parameter Muse Glimmer, Signaling Return to Open Weights

3 articles · Updated · The Register · Aug 7

Summary

  • Meta unveiled Muse Glimmer, a 30-billion-parameter large language model—its first open-weights release in more than a year.
  • The launch marks a renewed push into open weights, reviving the strategy behind its earlier Llama models after a long gap in public model releases.
  • Meta also indicated an open version of Muse Spark will follow, suggesting Muse Glimmer is the start of a broader rollout rather than a one-off release.
  • The move reopens competition over openly available frontier AI models as major developers face growing pressure over access, safety and regulation.
