Meta rolls out Muse Spark, its first public Superintelligence Labs model for multimodal, browser-based AI

Meta announced Muse Spark as the inaugural model from its newly formed Superintelligence Labs, describing the release as part of a “ground-up overhaul” toward delivering personal superintelligence for everyone ^{[1] [2]}.

Muse Spark is natively multimodal and built to reason, use external tools, produce visual chains of thought, and orchestrate multi-agent tasks; Meta also says it improved the model’s medical and health reasoning through collaboration with more than 1,000 physicians ^{[1] [3] [4]}.

Coverage notes Muse Spark is genuinely competitive across capabilities but does not top every benchmark—Decrypt reports that Google’s Gemini 3.1 Pro still leads certain leaderboards even as Muse Spark narrows gaps in some areas ^{[4] [2]}.

The release marks Meta’s first public Muse-family model and is presented as an initial step toward browser-accessible, personal superintelligence rather than a finished supremacy across AI benchmarks ^{[2] [1]}.
