# Meta releases Muse Glimmer 30B open-source agentic model

> Meta has open-sourced Muse Glimmer, a 30-billion-parameter model built for agent work that runs locally on a single GPU in a Mac or PC. Released August 10 under a permissive Apache 2.0 license, it handles tool invocation, multi-step reasoning, and multimodal input across text and images, and ships with a lightweight companion model for faster text generation. Meta says it distilled reasoning down from its larger Muse Spark 1.2. The pitch is that capable agents do not have to live in someone else's data center. A model small enough for consumer hardware, with weights you can inspect and modify, lowers the barrier for developers and tinkerers who want private, local automation without a metered API in the loop. The release arrives with a thesis attached. Mark Zuckerberg published a lengthy essay arguing that advanced AI should be distributed rather than concentrated in a few closed labs, a pointed contrast with OpenAI and Anthropic. Whether or not you buy the framing, a genuinely usable open agentic model on everyday machines is a meaningful data point in that debate.
