Meta Superintelligence Labs has launched Muse Spark, a native multimodal reasoning model that scores 52 on the Artificial Analysis Intelligence Index, placing it in the top 5 frontier models. This marks Meta's first frontier-class model and its first AI system without open weights, representing a strategic shift from its open-source Llama strategy. The model achieves comparable efficiency to Gemini 3.1 Pro while matching Llama 4 Maverick capabilities with over an order of magnitude less compute.

Meta has discontinued its Llama model line and launched Muse Spark as the foundation of its new AI strategy under Meta Superintelligence Labs. The model features a Contemplating mode for complex reasoning tasks and specializes in multimodal perception, health applications, and agentic tasks. Muse Spark is available today in Meta AI apps, with a private API preview for select partners.

Meta Superintelligence Labs has launched Muse Spark, its first model since Mark Zuckerberg restructured the company's AI division. The multimodal model now powers Meta AI's app and website in the US, with rollout planned for WhatsApp, Instagram, Facebook, Messenger, and Meta's smart glasses in coming weeks.

Meta announced Muse Spark, its first major large language model since hiring Scale AI's Alexandr Wang nine months ago for a $14.3 billion deal. The proprietary model emphasizes efficiency and multimodal reasoning over top-tier performance, marking a strategic shift from Meta's previous open-source Llama approach. Muse Spark will power Meta's AI assistant across Facebook, Instagram, WhatsApp, Messenger, and Ray-Ban glasses starting in coming weeks.
