At the Meta Connect 2026 Developer Conference, Meta unveiled a major functional enhancement for its personal AI agent application, Muse, and initiated a public early access program on September 25. This initiative is designed to expedite the development of multimodal and on-device AI agents. The upgrade zeroes in on system-level control, hardware synergy, and interaction innovation. It introduces digital avatars capable of supporting real-time video interactions, broadens the range of shopping ecosystem partners, and incorporates data connectors. The Mac application now boasts the ability to command the computer to execute complex tasks and is seamlessly integrated into Meta's AI smart glasses lineup, facilitating instant voice interactions. The testing phase adopts a Prompt trigger mechanism, with a priority on inviting highly engaged AI enthusiasts to participate and provide early, high-quality feedback. This strategic move highlights Meta's vision to propel AI agents from being confined to a single dialog box to becoming a cross-terminal, cross-system, round-the-clock assistant.
