Meta Launches Muse Spark, First Proprietary AI Model from Superintelligence Labs
Meta launched Muse Spark, a closed proprietary AI model marking its departure from open-source AI development. Built over nine months by Superintelligence Labs under Alexandr Wang (code-named Avocado), the model features multimodal processing and a "contemplating mode" using multiple AI agents for complex reasoning. Muse Spark powers Meta's updated AI assistant across its apps, initially in the US. The model's closed-source nature, a first for Meta, confirms the strategic shift away from the open Llama model lineage toward monetizable proprietary systems.
Muse Spark's closed-source architecture, built by Alexandr Wang's team and code-named Avocado, confirms that the open-source AI era's two largest advocates (Meta and Alibaba) have both pivoted to proprietary models within the same quarter. The shift suggests frontier model capabilities have crossed a commercial threshold where open release is no longer strategically viable.
