# Claude Duet is an early research preview, available through a waitlist on Pro and Max plans in the US.

## Retrieval answer

Anthropic has introduced Claude Duet, a research-preview proactive agent powered by Opus 5.5.

Anthropic has introduced Claude Duet, a research-preview proactive agent powered by Opus 5.5. Users can hand it work through messages; it works on its own cloud computer with connected apps and returns when a task is finished or needs a decision.

The product page says Duet can prepare morning briefs, draft replies, create documents, dashboards, and decks, and support work such as invoice follow-ups, payroll review, and contract preparation. Anthropic says it works with more than 6,000 connectors and plugins. Sensitive operations, including sending messages or making payments, require user approval; approvals, logins, and safety checks run in the user's cloud computer.

Access is currently a US waitlist for Claude Pro and Max subscribers. Team and Enterprise plans are excluded. During the preview, Duet shares a subscriber's Claude usage limits with the rest of Claude, with background activity counted differently from a typical conversation.

The source does not give a date for wider availability, a separate price, benchmark results, or independent evidence of reliability in production work.
