Meta today released Muse Glimmer, a 30-billion-parameter open-weight model designed to run autonomous AI agents directly on consumer hardware — pushing agentic workloads that normally depend on cloud infrastructure onto high-end Macs and PCs.

Just as notable as what the model does is how it's licensed. Glimmer arrives under the permissive, industry-standard Apache 2.0 open source license — the company's first fully open release since it succeeded its open-weight Llama family in April with the proprietary Muse Spark.

In fact, Muse Glimmer launches today with a more permissive license than Llama ever carried. Llama's bespoke community license drew years of criticism for restrictions like its 700-million-monthly-user cutoff; Apache 2.0 has no such strings, permitting unrestricted commercial use, modification and redistribution.

The weights are available on Hugging Face now. Wang said support is rolling out this week through Ollama, LM Studio, vLLM, SGLang, Together AI, Fireworks AI and OpenRouter, with optimized llama.cpp, MLX and ExecuTorch integrations landing in the coming days; Meta's blog post also names Unsloth as a local-runtime partner and points to PyTorch's TorchTitan for fine-tuning. The company says it is working with AMD, Arm, Dell, Intel and Nvidia to optimize performance across devices, and has published developer documentation covering custom agent scaffolds.

"Today we're also opening the weights for Muse Glimmer, a great 30B parameter dense model that can run locally," Meta co-founder and CEO Mark Zuckerberg wrote in a post on X (under his longtime handle @finkd). "Soon we'll also release the weights for Muse Spark 1.2, our latest foundation model. Meta is a strong supporter of open source and I'm proud of these releases."

That promised Muse Spark 1.2 release would be an even bigger shift: it's the frontier model behind Muse Code, the terminal coding agent Meta shipped just five days ago, and until today the entire Muse family w...
