Meta launches Muse Spark as the first model from Meta Superintelligence Labs

What Meta announced on X

On April 8, 2026, AI at Meta introduced Muse Spark on X as the first model in a new Muse family built by Meta Superintelligence Labs. The post emphasizes three technical claims at once: the model is natively multimodal, it supports tool use, and it includes multi-agent orchestration together with visual chain of thought.

That framing matters because Meta is presenting Muse Spark not as a simple chatbot refresh, but as a reasoning-oriented foundation for assistants that can combine modalities, tools, and coordinated sub-workflows.

What Meta's official announcement adds

Meta's newsroom post says Muse Spark is purpose-built for Meta's products and is now powering the Meta AI app and meta.ai. The company says the rollout will expand in the coming weeks to WhatsApp, Instagram, Facebook, Messenger, and AI glasses. Meta also says it will offer Muse Spark in private preview via API to selected partners.

Meta calls Muse Spark its most powerful model yet.

The company says larger models are still in development, positioning Muse Spark as an early point on a broader scaling path.

Meta also says future product features will be able to cite recommendations and content people share across its apps.

Taken together, the announcement points to a model strategy centered on product distribution first. Muse Spark is not being introduced only as a lab benchmark or an isolated API launch. It is being used immediately inside Meta's own consumer surfaces while a narrower partner API program starts in parallel.

Why this matters

The significance of Muse Spark is not just that Meta has a new model. It is that Meta Superintelligence Labs has now put its first model directly into products with massive built-in distribution. That creates a different competitive profile from a pure API-only release. If the rollout goes as described, Muse Spark will quickly matter because of where it is deployed, not only because of how it benchmarks. An inference from Meta's launch plan is that the company sees tightly integrated product deployment and selective API access as the fastest way to turn model capability into user reach.
