Mark Zuckerberg is launching a new AI model and a vision for a more open form of superintelligence.
The social media giant unveiled Muse Glimmer on Monday and said it is an open-weight, agentic model small enough to run on a Mac or PC. Open-weight means users can download and customize the model to run it locally instead of in the cloud.
Meta also plans to release an open-weight version of Muse Spark, its most powerful AI model, soon, Zuckerberg added.
Meta said it trained Glimmer on Muse Spark using a process known as distillation, where a smaller model learns from a larger "teacher" model.
Meta said that Glimmer, the latest model rolled out by the company's Superintelligence division led by former Scale AI CEO Alexander Wang, can perform complex reasoning and handle a broad range of agentic tasks while running on a consumer device with a single graphics card.
Glimmer can break a task, such as coding or admin work, into steps. Meta said it "performs strongly for its size class" on several benchmarks for large language models.
The Meta CEO also published a 6,500-word essay from Zuckerberg making a positive case for superintelligent AI.
In the essay, titled "The Future Is for Everyone," Zuckerberg wrote that it was "surprising" that the discourse from so many of the people developing AI was so "filled with doom."
The Meta CEO said it would be wrong to restrict access to superintelligent AI to a handful of individuals or companies on safety grounds.
"Some argue that superintelligence itself or a small set of experts who control it should decide what is best for humanity. We disagree," Zuckerberg wrote.
Meta's model launch comes as the tech industry is embroiled in a debate over open weight AI. Last month, nearly every major AI lab — including Meta — signed a public letter advocating for open-weight models, after the US government suggested it could sanction Chinese open models that were found to have distilled AI models built by their US rivals.
"Foreign labs currently hold several advantages here since American labs have to comply with many additional restrictions on training data," Zuckerberg wrote in his essay. "US policy must reduce this additional friction if we want American open source models to lead over time."
