Meta Superintelligence Labs is launching its first model since Mark Zuckerberg spent billions overhauling the company’s AI efforts. Called Muse Spark, the model now powers the Meta AI app and the Meta AI website in the US, per the company’s announcement. In the coming weeks, Meta says, it will appear in WhatsApp, Instagram, Facebook, Messenger, and Meta’s smart glasses, as well as roll out in other countries.
Like Google Gemini, which easily integrates into Google’s product suite, Meta touts Muse Spark as “purpose-built for Meta’s products.” The model, the first in a new series, will also be available to some of Meta’s partners in private preview” via the API. The company promises the ability to run multiple AI sub-agents to handle queries better and faster, as well as support for multimodal input that includes both text and images. The latter is particularly relevant to Meta’s AI-powered camera glasses, which it’s bet on as the (latest) future of computing. It lets users toggle between a faster “Instant” mode and a “Thinking” mode that’s supposed to deliver more thoroughly reasoned results, similar to options like Microsoft’s Think Deeper.
Meta also highlighted that Muse Spark can answer “complex questions in science, math, and health.” Health-focused AI chatbots have been a controversial topic in recent months, as they handle sensitive personal data and can propagate misinformation. Meta said that Muse Spark’s multimodal perception is “especially valuable for health” and can “navigate health questions with more detailed responses, including some questions involving images and charts.” Meta may be looking to compete with OpenAI’s ChatGPT Health and Anthropic’s Claude for Healthcare, which both debuted in January. In its announcement, it showed its chatbot estimating a calorie count for a meal — a popular, but often hit-or-miss, use of AI tech.
In the future, Meta hopes the model will power new features “that cite recommendations and content people share across Instagram, Facebook, and Threads.” The company also said that it has larger models in development and hopes to open-source future versions. It describes Muse Spark as an “early data point” on the trajectory of its new Muse series.
The Muse series is set to be Meta’s second major foray into powerful AI, following its Llama models. Zuckerberg revamped the company’s AI program after the delayed and disappointing release of Llama 4 in 2025.
