Overview

  • Muse Spark, announced Wednesday, is the first model from Meta Superintelligence Labs led by Alexandr Wang and now powers the Meta AI app and website in the US.
  • The model is natively multimodal with tool use, visual chain of thought and a Contemplating mode that coordinates multiple agents for tougher tasks, and Meta says it tested safety and added guardrails for high‑risk prompts.
  • Meta will roll it out next to WhatsApp, Instagram, Facebook, Messenger and Ray‑Ban Meta glasses, and it opened a private API preview for select partners with paid access planned later.
  • The release is proprietary at launch as Meta shifts to a hybrid approach that could open‑source some future versions, supported by a rebuilt AI stack and new infrastructure such as the Hyperion data center.
  • Meta’s stock rose about 8–9% Wednesday after the announcement, as the company tries to regain ground on OpenAI, Anthropic and Google following last year’s LLaMA 4 underperformance.
