Key facts
- Meta launched an AI model called Muse Glimmer.
- Meta plans to release the weights for Muse Spark 1.2.
- Mark Zuckerberg is pushing for U.S. leadership in open AI.

Meta is moving to open source its most powerful artificial intelligence model, a decision that positions the company against rivals OpenAI and Anthropic, according to CNBC. The report says Meta has launched a model called Muse Glimmer and plans to release the weights for a model named Muse Spark 1.2.
The strategy is being driven by chief executive Mark Zuckerberg, who is pushing for U.S. leadership in open AI, CNBC reported. Releasing model weights openly allows outside developers and organizations to access and build on the underlying technology, a different approach from companies that keep their most advanced models closed.
By making its most capable systems available on an open basis, Meta is drawing a contrast with OpenAI and Anthropic, both of which are prominent developers of large AI models. CNBC characterized the move as a swipe at those competitors.
The launch of Muse Glimmer, alongside the planned release of Muse Spark 1.2 weights, signals Meta’s continued investment in advanced AI development and its intent to shape how the technology is distributed. The company’s approach centers on open access as a competitive differentiator.
Beyond product positioning, the effort is tied to a broader argument about national competitiveness. Zuckerberg’s push for U.S. leadership in open AI frames Meta’s releases as part of an effort to keep influential AI development anchored in the United States.
Why it matters
How leading AI companies choose to release their most powerful models shapes who can build on the technology and how quickly it spreads. Meta's open approach contrasts sharply with the more closed strategies of OpenAI and Anthropic, and it feeds into a wider debate about U.S. leadership in artificial intelligence.
