Meta thinks the next front in the AI race may be sitting on your desk.On Aug. 10, Meta released Muse Glimmer, a 30-billion-parameter AI model designed to run locally on a Mac or PC with a single consumer GPU. Its weights are available to download from Hugging Face under a permissive Apache 2.0 license, allowing developers to use, modify, and build products with the model for free.That means Muse Glimmer can operate without sending every request to a distant data center. It can also work without an internet connection, provided the computer running it has enough memory and processing power.

For anyone ready to open an app and start chatting, however, there is a catch: Muse Glimmer is a developer release. Meta is supplying the model that can power an AI agent, rather than a consumer product that immediately manages your inbox or reorganizes your desktop.What can Muse Glimmer actually do?Meta built Muse Glimmer for "agentic" work, meaning it can take a goal, divide it into steps, and use connected tools to complete parts of the task. The company imagines local agents that could manage schedules, draft messages, organize files, and write or debug code.The model can process images alongside text, perform multi-step tasks, and attempt recovery when a tool fails. Meta says it was trained on data from more than 100 languages.Fitting those abilities onto one computer required some downsizing. At full precision, Muse Glimmer would need more than 55 GB of memory. Meta compressed the model to below 20 GB, leaving additional room for its working memory and image-processing system.Even so, "runs on your laptop" is doing some work here. Meta designed the compressed version to fit within a 24 GB or 32 GB memory envelope and tested it on hardware, including Apple’s M4 Max and M5 Max chips and Nvidia’s RTX 5090. Your average work laptop may sit this one out.
