Meta introduced Muse Spark on April 8, the first model from Meta Superintelligence Labs—the division assembled around Chief AI Officer Alexandr Wang over nine months after his $14 billion hiring deal. Muse Spark is natively multimodal, supports visual chain-of-thought reasoning, parallel subagent orchestration, and tool-use, and already powers the Meta AI app and website with WhatsApp and Instagram rollout planned. Meta acknowledges the model trails frontier competitors in coding but is competitive in multimodal understanding and health reasoning, positioning Muse Spark as the foundation of a new scaling series.
