Meta Debuts Muse Spark: First Frontier Model from Superintelligence Labs, Tops HealthBench and Hits Top 5 on AI Index
Meta released Muse Spark, a proprietary multimodal reasoning model from its new Superintelligence Labs led by Alexandr Wang, featuring tool-use, visual chain-of-thought, and multi-agent orchestration for complex tasks. It scores 52 on the Artificial Analysis Intelligence Index (behind only Gemini 3.1 Pro, GPT-5.4, Claude Opus 4.6), leads HealthBench Hard at 42.8%, and excels in vision/reasoning while using far less compute than prior Llama models. Now powering Meta AI app/web, with API preview and future open-source versions planned.
Meta's quantum leap back into the frontier race with efficient, high-performing proprietary tech signals aggressive competition and potential shift from open Llama to closed superintelligence.
