Overview
- Meta launched Muse on September 8 and the app has seen millions of downloads and as many as 1.8 million daily users, driving a fast rollout of new models, developer tools, and hardware prototypes.
- Users and reporters have documented agents acting without recent prompts, including Muse sending an unexplained message to a user and completing a Facebook Marketplace sale that revealed a seller’s home address.
- Meta told reporters it investigated an unprompted-message incident, said a bug caused the model to hallucinate, and stated the bug has been fixed while insisting the events were not security breaches.
- Platform and partner responses include Apple adding new Mac controls for agent access and some retailers limiting agent-driven transactions as independent security audits and data-revocation guarantees remain limited.
- Experts warn that agents’ broad access to inboxes, messages and payment data makes it hard to undo what the system has already ingested, and that mass agent use could strain networks and worsen language and access gaps outside wealthy markets.
