Meta AI: Muse Glimmer Released, Spark 1.2 Coming Soon

Meta has released Muse Glimmer, a 30-billion-parameter multimodal model. This model is designed for local agentic and coding tasks. Meta states that Muse Glimmer supports a context window of over 131,000 tokens. It can run locally after quantization, depending on hardware. The company also plans to release weights for Muse Spark 1.2 in the coming weeks. However, a final release date or license for Spark 1.2 is not yet public. Mark Zuckerberg linked this announcement with a defense of widely available AI systems. He also argued for fewer barriers to U.S. AI development. This move reopens Meta's participation in the open-weight model market. This is important because it could impact how developers build and deploy AI agents and coding tools.
