Meta released Muse Glimmer, a 30-billion-parameter open-weight dense model with a context window exceeding 120,000 tokens.

Meta released Muse Glimmer as a 30-billion-parameter dense model. “Open-weight” means the model’s trained weights are being made available under the release’s applicable terms, while “dense” indicates that its parameters are not described as a mixture-of-experts architecture.

Muse Glimmer supports a context window of more than 120,000 tokens. Context-window size measures the amount of tokenized input and output the model can process in one interaction; it is separate from the model’s 30-billion-parameter count.

NVIDIA described Muse Glimmer as designed for local AI and agentic workflows on NVIDIA platforms. The supplied source did not provide benchmark scores, training-compute figures, licensing details, memory requirements, or a complete list of supported NVIDIA systems.
