Goodbye, Llama? Meta launches new proprietary AI model Muse Spark - first since Superintelligence Labs' formation

Key Points:

• Meta has launched Muse Spark, a new proprietary AI model led by Chief AI Officer Alexandr Wang, marking a significant shift from its open-source Llama family to a more closed, high-performance system focused on "personal superintelligence."
• Muse Spark features advanced multimodal reasoning capabilities, including visual chain of thought and multi-agent orchestration, achieving top-tier benchmark scores that place it among the world's leading AI models in vision, health, and efficiency.
• The model is highly efficient due to "thought compression," using significantly fewer computational resources than previous Meta models and competitors, though it still trails some rivals in agentic task execution.
• Meta is deploying Muse Spark across its app ecosystem to enhance personalized shopping, health reasoning, and interactive experiences, but the model is currently proprietary, accessible only via Meta’s AI app, website, and limited private API preview.
• Despite assurances that existing Llama models remain open source, the future of the Llama family is unclear as Muse Spark signals a strategic pivot by Meta toward proprietary AI development amid increasing global competition.
