Meta Launches Personal AI Agent 'Muse' in the US — A Design That Puts Permission Decisions Outside the Model
Meta launched Muse in the US on September 8, 2026, a personal AI agent that operates email, payments, and a browser on a user's behalf. A technical post published the same day discloses the design: a separate agent called Sentinel holds sole permission authority on a dedicated VM, and the agent never sees real credentials. The bug bounty pays up to $300,000.
