Meta released Muse Spark, the first AI model from its newly formed Superintelligence Labs division led by Alexandr Wang. The model is now available on Meta's AI site and app, marking the debut of the company's rebuilt AI infrastructure. Meta's stock jumped 8% following the announcement.

The release represents the culmination of Meta's months-long AI overhaul, which included a $14 billion investment in Scale AI to bring Wang in-house. The company engaged in an expensive talent war, poaching employees from competitors with high-paying packages to staff its Superintelligence Labs division.
