Meta has released two new models, Muse Spark 1.2 and Muse Glimmer 30B, with Glimmer being an open-weights model distilled from Spark. While Spark 1.1 (an earlier version of Spark) leads the MCP-Atlas leaderboard for tool-use protocols, Glimmer is not yet on this benchmark. Meta's own figures show Glimmer excelling at protocol-based agentic tasks but underperforming in terminal and desktop control compared to models like Qwen3.6-27B. Additionally, Glimmer exhibits a notable vulnerability to prompt injection attacks, with a 28.4% attack success rate. AI
IMPACT New open-weight models with specialized capabilities could accelerate agent development, but safety concerns require careful consideration.
