🤖 Anthropic launches Claude Duet preview — a competitor to ChatGPT Dots

Claude Duet is a standalone application where Claude operates as a proactive always-on agent: morning briefs, email and calendar, and background tasks on a cloud computer. Before sending messages, making payments, or deleting data, the agent requests confirmation. The model is Claude Opus 5.5.

🌍 Proactive always-on agents are entering the mass market: Anthropic competes with ChatGPT Dots and Meta Muse, while mandatory confirmation for sensitive actions sets a new UX standard for autonomous agents.

👤 A waitlist is available for Claude Pro ($20/month) and Max subscribers in the US: Duet is included in the plan, but background work consumes limits faster than regular chat. There are no benchmarks in the announcement — only scenario descriptions.
