Meta Platforms Inc. on Wednesday unveiled its newest artificial intelligence model, Muse Spark, marking the first major release from its recently restructured AI division as the company pours billions of dollars into competing with rivals such as OpenAI, Google, and Anthropic.
The model, developed by Meta’s Meta Superintelligence Labs, is positioned as the first in a new series of AI systems designed to deliver advanced reasoning and multimodal capabilities. Meta’s leadership has framed the release as a pivotal step in its long-term strategy to regain momentum in the AI race after mixed reviews for its previous flagship, Llama 4.
“Muse Spark is a powerful foundation, and the next generation is already in development,” Meta said in a company blog post, describing the model as “small and fast by design, yet capable enough to reason through complex questions in science, math and health.”
Available immediately on Meta’s Meta AI app and website, Muse Spark is slated to replace older Llama models across Meta’s suite of products, including WhatsApp, Instagram, Facebook, and Meta’s smart glasses, the company said.
The launch comes amid an aggressive spending push by Meta’s CEO Mark Zuckerberg, who last year backed a major overhaul of the company’s AI efforts. Meta hired Alexandr Wang, former CEO of Scale AI, under a deal worth roughly $14.3 billion to lead the superintelligence team and recruited other top AI engineers with competitive compensation packages.
In its announcement, Meta emphasised that Muse Spark was built “to support complex reasoning and multimodal tasks” and would power a range of new and existing AI‑driven features across the company’s products. “Over the last nine months, Meta Superintelligence Labs rebuilt our AI stack from the ground up,” the company stated.
The broader context for the launch reflects Meta’s intense focus on AI infrastructure and talent acquisition — components of a spending strategy that has drawn scrutiny from investors. The company has reported plans to substantially increase capital expenditures this year to support AI development, data centres, and customised computing hardware.
Meta’s stock responded positively to the announcement, with shares rising sharply in trading on Wednesday, erasing some earlier losses tied to concerns about the company’s hefty AI investments.
While Muse Spark has been benchmarked by the company against competitors’ models, independent performance assessments are still pending. Meta’s executives say the model represents only the first phase of a broader effort toward what they describe as “personal superintelligence,” with larger, more capable models under development.
