Meta's Glimmer is a 30B open model built to run agents on your computer

Meta released Muse Glimmer, an open-weight model with 30 billion parameters under an Apache 2.0 license. It is the open counterpart to Muse Spark, Meta's more capable closed model. Glimmer is built to run agents directly on a user's machine: it can use tools, write and debug code, manage files, and read the contents of screenshots. It takes text and image input, supports more than 100 languages, and runs on a single consumer GPU on a Mac or PC with no internet connection.

Meta's pitch, reported by TechCrunch, is a personal agent that handles scheduling, drafts messages, and organizes files, with processing kept on the device so personal data does not leave it. Zuckerberg frames this as the start of an era of personal empowerment, with agents working around the clock for their owner. The strategy has a clear line through it: Glimmer is open, while the stronger Muse Spark stays closed.

Why it matters

For developers and privacy-conscious users, an Apache 2.0 agent model that runs offline on one GPU is something you can actually deploy and modify without sending data to someone else's servers. The catch is that Meta keeps its best model closed, so the strongest capability is not part of what it opened.
