Meta starts its new Muse AI model family with Muse Spark in a broader AI strategy reset

Meta has launched a new lightweight AI model called Muse Spark, the first release in its new Muse family, in what the company defines as a broader reset of its AI strategy. That reset appears to reflect both a response to Llama 4’s weak reception and a shift toward a new generation of models built by Meta’s Superintelligence team, with more emphasis on practical consumer features such as reasoning modes, multimodal input, and agent based task handling. For now, Meta says it is focusing on getting the fundamentals right before moving on to more capable Muse models.

The model includes Instant and Thinking modes, letting users choose between faster replies and responses that take more time to reason through a prompt. Meta also plans to introduce a future Contemplating mode for harder tasks, using multiple AI agents working in parallel. Muse Spark is natively multimodal as well, with support for text, images, video, and audio, so users can do things like take a photo and ask Meta AI about what they are seeing. Meta says the model will continue improving over time and that future Muse models may be open sourced, but that's not the case for now.

Muse Spark is currently available only through the Meta AI app and the meta.ai website in supported regions, starting in the United States. It is not yet available in Facebook, Instagram, or WhatsApp, though Meta says it plans to expand access to those platforms and more countries in the coming weeks.
