Meta just dropped its biggest AI product shift since Llama 4. The company announced Muse Spark on April 8, a new AI model built by Meta Superintelligence Labs that introduces selectable operational modes designed for different levels of cognitive demand.
The model represents a notable strategic pivot. Meta is moving away from its open-source AI playbook and toward hosted, integrated products embedded directly into its ecosystem of apps. The initial rollout is starting in the US across the Meta AI app, with expansion to Instagram, Facebook, WhatsApp, and Messenger, and Ray-Ban Meta smart glasses coming shortly after.
What the modes actually do
Muse Spark launches with two active modes and two more on the roadmap. The first, called Instant, does exactly what you’d expect: fast, lightweight responses for quick questions and simple tasks.
The second mode, Thinking, handles complex tasks like document analytics and nutritional assessments based on photos. Point your camera at a plate of food and the model will break down what it sees.
