Muse Spark is the first effort of the super expensive Superintelligence Labs, and is the first model released since the Llama models that have been powering Meta since May 2025.
It uses a multi-agent workflow — and Meta says it «understands the world around you,» and can help «with the things that matter most,» meaning it likely has access to your personal social media data, although Meta doesn’t explicitly say so.
The model scores pretty well at benchmarks. Even if it doesn’t quite push the frontier, it manages to beat GPT 5.4 in some cases.
Meta bills Spark as «step one,» with bigger models building on it already in development. «There are certainly rough edges we will polish over time in model behavior,» Meta’s Superintelligence chief Alexandr Wang says.
