Meta launches personal agent Muse with safety deep-dive, but privacy VM is missing and data harvesting raises alarm
simplexmethod · x · 2026-09-16
Meta Superintelligence Labs launched Muse, a personal agent that runs inboxes, calendars and shells unattended, spawning subagents and building its own tools. The accompanying safety post details: model training for zero-shot tool calling, long context, prompt-injection awareness and multi-agent coordination; an assume-breach architecture with an isolated harness, no real credentials, and a non-overridable Sentinel gate on all external interactions; hardening via dogfooding, agentic red teaming and a newly opened bug bounty. Critics counter that Muse is generating vast actionable personal training data through its connectors — 'Onavo built in house' — while the Confidential VM promised to cryptographically block Meta's access isn't actually live yet, and most users would never enable it anyway.
