Muse Glimmer 30B is Meta’s open agent model for local use. Unlike Muse Spark, the focus is a downloadable checkpoint that combines image understanding and controllable reasoning in a compact architecture.

The weights are released under Apache 2.0. Meta positions Glimmer for a single consumer GPU, quantized variants, and local runtimes such as llama.cpp, MLX, and ExecuTorch.
