Meta launches Muse Glimmer, open-weight edge AI model, challenging closed models

Meta released Muse Glimmer, a 30B parameter open-weight model under Apache 2.0, optimized for local agentic inference on consumer hardware (24GB VRAM). Zuckerberg's essay and interviews frame this as a challenge to Chinese open-source and a swipe at OpenAI/Anthropic's closed approach, reinforcing Meta's open-source strategy.
