Meta returns to open source with Muse Glimmer, an Apache 2.0 licensed 30B parameter AI model optimized for agents — available now

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
