Overview
- Meta's Muse Spark, which launched Wednesday, now powers the Meta AI app and website and will expand to Facebook, Instagram, WhatsApp, Messenger, and Ray‑Ban smart glasses in the coming weeks.
- The model handles text, images, and audio, offers Instant and Thinking modes with a coming Contemplating mode that coordinates subagents for harder tasks, and adds a shopping feature that pulls creator content from Meta apps.
- Access is limited to in‑product use and a private API preview for select partners, with paid API access planned later, while Meta says it hopes to open‑source some future versions.
- Meta published competitive but not leading benchmark results and said a third‑party found high “evaluation awareness,” which the company reviewed after safety testing and deemed not a reason to delay release.
- Shares rose about 8% to 9% after Meta said Spark matches older Llama 4 midsize capability using roughly ten times less compute, reflecting the company’s reboot after Llama 4 and its $14.3 billion Scale AI deal.
