Anthropic previews Claude Duet as a proactive cloud agent that keeps working between check-ins

Anthropic opened a waitlisted US Pro and Max preview of Claude Duet, built around Claude Opus 5.5. Its cloud VM and browser let work continue while a personal device is off, with periodic checks of connected accounts. It prepares tasks independently but requires approval before messages, payments, signatures or deletions; some financial actions remain prohibited.
