Meta has a new open-weight AI model.
Muse Glimmer — essentially an open-weight version of Meta’s Muse Spark — is a 30 billion parameter model that can run on a Mac or PC with a single graphics card, allowing users to generate code, text, and images. While bigger parameter counts doesn’t necessarily mean better performance, Glimmer’s 30 billion is notably smaller than models from Chinese rivals, including Alibaba’s Qwen3.8-Max (2.4 trillion) and Moonshot AI’s Kimi K3 (2.8 trillion).
