Meta Unveils 'Muse Spark' — First AI Model from Its Superintelligence Lab

Meta has unveiled Muse Spark, the first AI model from its Meta Superintelligence Labs. The model represents the inaugural output from a new division created after CEO Mark Zuckerberg grew dissatisfied with Meta's AI progress. He recruited Scale AI co-founder and CEO Alexandr Wang, investing $14.3 billion for a 49% stake in Scale AI.

Muse Spark is a natively multimodal reasoning model supporting tool use, visual chain of thought, and multi-agent orchestration. A 'Contemplating' mode allowing multiple AI agents to collaborate on complex problems will be added later, enabling scaled test-time reasoning without drastically increasing latency.

The model will roll out to WhatsApp, Instagram, Facebook, Messenger, and Ray-Ban Meta AI glasses. Health-related question support is also planned, though the requirement to log in with a Meta account raises privacy concerns. Benchmarks show Muse Spark excels at visual STEM questions but lags rivals in coding ability. Meta's AI-related capital expenditures are projected to reach $115-135 billion in 2026, up from $72 billion in 2025.
