Meta has unveiled Muse Spark, its first AI model since CEO Mark Zuckerberg’s multibillion-dollar investment in talent and infrastructure. Designed for social media applications, Muse Spark powers a smarter version of Meta AI, offering more visual and personalized responses using content from Instagram, Facebook, and Threads. The model supports healthcare and shopping features and will be released initially in a private preview. Unlike the open Llama models, Muse Spark is closed, with Meta planning to open-source future versions.
