Meta has released Muse Spark, the first major AI model from its newly formed Meta Superintelligence Labs. The division was established following Meta's $14 billion deal to bring in Scale AI's Alexandr Wang. Muse Spark is the inaugural model from the Muse series — a new model family distinct from the open-source Llama line. The launch arrives as Meta commits between $115 and $135 billion in AI-related capital expenditures for 2026, signaling the company is moving beyond open-source community releases toward proprietary frontier model development. The split strategy — open Llama for ecosystem, closed Muse for competitive advantage — marks a significant evolution in Meta's AI approach.
