#MetaReleasesMuseSpark


Meta has officially launched Muse Spark, the flagship model from its newly formed Meta Superintelligence Labs. Released on April 8, 2026, and led by Chief AI Officer Alexandr Wang, Muse Spark represents a ground-up overhaul of Meta’s AI stack following the Llama series.
Designed as a multimodal reasoning powerhouse, Muse Spark excels in agentic workflows, allowing it to coordinate multiple sub-agents simultaneously to solve complex tasks. Key features include an Instant mode for speed and a Thinking mode for deep reasoning. It currently powers Meta AI across Facebook, Instagram, and WhatsApp, with specialized capabilities in health, shopping, and social content search. While proprietary for now, the model is built for efficiency, successfully rivaling top-tier competitors like GPT-5.4 and Gemini 3.1 in specific reasoning benchmarks.
