404 Media Exposes Meta's Muse AI Agent Calls as Human Call Center Work

On September 23, 404 Media published an investigation revealing that Meta's AI agent Muse, promoted as capable of calling businesses on users' behalf to book restaurants or haircuts, actually routed some calls to human call center agents — with testers only informed after calls ended.

Confirmed

Meta heavily promoted Muse's outbound calling capability around September 16, when lead engineer Ryan briefed the team on the feature
Internal communications obtained by 404 Media showed Meta told employees it had "added a layer of human agents to complete calls"
Testers were only told the other party was human after calls ended
@VraserX noted the calls were quietly taken over by outsourced human contractors
Citing Reuters, @robleclerc reported Muse has over 2.5 million downloads and can book appointments, check inventory, and ask prices at US businesses

Why it matters

The report strikes at a core AI industry controversy: marketing "AI agents" while relying on hidden human labor (ghost work), potentially misleading users and investors
@VraserX argued human-in-the-loop is acceptable in principle — the problem is concealment: users deserve to know if their personal AI calls a doctor, bank, or lawyer
With Muse past 2.5 million downloads and tech giants racing to ship AI agents, the report is a cautionary case for assessing the true maturity of such capabilities
