Muse Glimmer, sitting around 30 billion parameters, ships with an Apache 2.0 license, meaning the weights on Hugging Face are yours to download, modify, and build on top of, no permission needed. Meta’s Superintelligence Lab took its larger Muse Spark and essentially had it teach a smaller, leaner version to think as it does. At full precision, Muse Glimmer would eat up 64GB of video memory, way more than most people have lying around, especially in this AI-inflated RAM pricing age.
