Meta drops Muse Spark natively multimodal reasoning model

Meta is pivoting from its open-weights strategy to challenge frontier models with this proprietary, reasoning-focused architecture. Muse Spark prioritizes vertical specializations like health and visual programming, utilizing a 10x compute efficiency gain over Llama 4. This shift signals the end of the Llama era as Meta leverages its unique social data moat to build personalized, autonomous agents for its AR ecosystem.
