According to CoinMeta, Anthropic announced that Claude Duet has sent out invitations to all the previous subscribers from the waiting list who are American citizens, including Pro, Max, and Ultra. New users can still apply, but the service is not yet available outside of the United States. To encourage users to try it out, Anthropic is also offering additional free quota reset opportunities: Pro times for Max users, and Ultra times for Claude users. Each time a user utilizes this option, their weekly quota for Claude is restored to its full amount, and the applicable 5-hour session limit is also reset. The unused quotas will expire on December 15th. Claude Duet itself does not incur a separate fee, but it shares the subscription quota with Claude and Claude Code. Anthropic stated that they plan to make the service available in more countries outside of the United States soon.
