Meta Launches Muse Spark, Superintelligence Labs' First Model

Meta announced on Wednesday, April 8, 2026, the release of Muse Spark, the first artificial intelligence model created by the new Meta Superintelligence Labs. The announcement came directly from the company's official blog and marks the tangible result of Mark Zuckerberg's billion-dollar effort to regain ground in the AI race.

The model is the kickoff to a new series called Muse and was built in just nine months by the team led by chief AI officer Alexandr Wang. In practice, it is designed to be small and fast, but already shows the capability to solve complex problems in fields such as science, mathematics, and health. According to Meta's official statement, the Muse Spark is currently the company's most powerful model.

It is already operational in the Meta AI app and on the meta.ai website. In the coming weeks, the model will replace the old Llama in chatbots on WhatsApp, Instagram, Facebook, Messenger, and even the company's smart glasses. Meta also plans to provide private preview access via API to some selected partners.

Unlike the previous open model strategy, the Muse Spark is closed; neither the code nor the architecture will be publicly disclosed. This shift reflects the company's new priority: creating more integrated AI products focused on its own platforms rather than donating technology to the market.

The announcement has already made waves in the market. Meta's stock rose about 5% to 8% shortly after the news, indicating that investors are betting on the company's ability to compete on equal footing with rivals like OpenAI, Anthropic, and Google.

Meta also hinted that the next generation of the Muse model is already in development, suggesting that the pace of releases is likely to accelerate in the coming months.
