Meta returns to open models with Zuckerberg's plan to out-copy China and sell compute by auction
Key takeaways
  • Meta released Muse Glimmer, a 30B open agent model requiring under 20GB RAM.
  • Zuckerberg defended distilling rival models to ensure US leadership over China.
  • The release comes from the new Meta Superintelligence Labs division.
  • An open-weight version of Muse Spark 1.2 is expected soon.
Full story

Meta has introduced Muse Glimmer, the first open model from its newly formed Superintelligence Labs. This 30 billion parameter agent model is designed to run on consumer hardware, requiring less than 20 GB of memory once weights are compressed.

In a strategic essay accompanying the release, Mark Zuckerberg argued for fewer restrictions on US AI labs. He explicitly defended the practice of distilling models from other companies, framing it as necessary to maintain American leadership against China.

The move signals a return to aggressive open-sourcing by Meta, contrasting with the closed approaches of competitors like OpenAI and Anthropic. An open-weight version of Muse Spark 1.2 is reportedly expected to follow soon.
