Meta Debuts Muse Spark Reasoning Model to Power Personal Superintelligence

Apr 9, 2026 · Updated Apr 25, 2026

Meta released Muse Spark, the first model from its new Superintelligence Labs. It is a natively multimodal reasoning model (AI that processes text and images simultaneously) built on a rebuilt infrastructure. The model now powers Meta AI across WhatsApp, Instagram, and Facebook, offering both instant and thinking modes.

This launch marks a strategic pivot after Meta spent nine months rebuilding its AI stack. While previous efforts focused on the open-source Llama series, Muse Spark is a proprietary model designed to close the performance gap. It uses multi-agent orchestration (multiple AI agents working together) to match the reasoning power of frontier models.

You can access the model today through the Meta AI app. New features include a Shopping mode for recommendations and specialized health reasoning developed with 1,000 physicians. A private API preview is open to select partners, with plans to open-source future versions as the Muse family scales.
