Meta on Monday released Muse Glimmer, an open-weight model designed to power AI agents locally on consumer hardware, providing the clearest picture yet of what CEO Mark Zuckerberg’s vision of “personal superintelligence” could look like in practice.
The 30-billion parameter model is essentially an open version of Meta’s most powerful closed model, Muse Spark, which the company debuted in April. Glimmer’s weights are available under the permissive Apache 2.0 license, so developers can download them and modify as necessary.
Glimmer is designed to run AI agents that can perform multi-step tasks — like call tools, write and debug code, work with files and screenshots, and execute on a task over an extended workflow — locally on a Mac or PC with a single consumer GPU. It supports text and images, and was trained across more than 100 languages, the company said.
Meta imagines Glimmer being used for things like managing schedules, drafting messages, and organizing files — tasks that would require large amounts of access to personal data. By processing the information on a user’s device instead of sending it to the cloud, Meta is laying the groundwork for a more privacy-sensitive personal agent. Glimmer is also designed to be “always-on” and able to operate “anywhere, anytime, with or without an internet connection.”
