# Meta releases Muse Glimmer multimodal model openly on Hugging Face

> Meta has quietly released Muse Glimmer, a 30-billion-parameter dense multimodal model with a 128K context window, under a permissive Apache 2.0 license on Hugging Face. The notable thing is not raw size but reach: quantized to 4-bit, it runs in under 20GB, which means it fits on a single consumer GPU or a capable Mac, no data center required. That combination of open weights, a business-friendly license, and modest hardware demands is exactly what independent developers and privacy-conscious users have been asking for. It positions Muse Glimmer as a smaller, more practical sibling to Meta's earlier and heavier Llama 4 releases. Meta also signaled that the closed Muse Spark 1.2 weights will eventually be opened, though it has not committed to timing. For a technologist, the appeal is concrete: a genuinely multimodal model you can download, run locally, and build on without per-token fees or a cloud dependency, which keeps the open-weights lane competitive as frontier labs push their proprietary systems.
