Notable: frontier-lab developer (Anthropic). Announced 2026-10-21 as a research preview; invitations go out in waves from the waitlist. Apps for iOS and Android; the announcement also lists claude.ai. Users can't choose the model — Duet picks the effort level itself. Blocked even with approval: trading securities, moving money between accounts, accessing someone else's account. Anthropic says it may misjudge urgency and is weaker at personal errands than work tasks. Product page: https://claude.com/product/claude-duet.
