Anthropic releases personal agent Claude Duet, built on the Opus 5.5 model

Anthropic has released a personal agent app called Claude Duet, positioned as a "proactive agent" that can run in the background and proactively push tasks to users; it is currently in research preview with a waitlist. The tool is built on the flagship Opus 5.5 model released at the end of September, and it pushes a daily morning briefing from connected apps, notifies users when something needs attention, and requires user approval for some tasks. Mike Krieger, co-lead of the Anthropic Labs team, says it can judge when to act proactively; Karan Ahuja, who leads Duet development, previously headed product management at Meta Superintelligence Labs.

Anthropic CEO Dario Responds to Safety Concerns in a Long Post, Reveals High-End Model Was Held Back for Four Months

Anthropic CEO Dario posted a long message on X responding to questions from AI safety investigator Nathan Calvin, disclosing for the first time that the company had already trained a high-end model at the Mythos level as early as February this year. Because its cybersecurity defense mechanisms were not yet complete, it was released only to a very small number of partners, and was not opened to the public until the safety guardrails were in place in June—about four months in total. He also listed the costs the company has proactively borne for safety, including a large number of false positives caused by biological risk filtering, pushing for legislation such as California SB 53, and a plan to commit 5% of the company's shares to a public interest fund. Dario said this approach amounts to competing toward a higher standard, while Calvin questioned how much more the company can concede in the race for the sake of safety.

Anthropic opens Claude Duet research preview to Pro and Max users in the US

On October 21, 2026, Anthropic opened the Claude Duet research preview. Built on Claude Opus 5.5, the app turns Claude into a proactive agent that can proactively surface to-dos, continue executing tasks after the user leaves, and confirm before acting on the user's behalf. Access is available through a waitlist, starting with Pro and Max users in the US, and is offered via standalone iOS and Android apps and the claude.ai entry point. During the preview period it is included in the Pro and Max plans and is subject to the same usage limits. The app can call on more than 6,000 connectors and plugins in the Claude Marketplace; user approval is required before sending messages, making payments, signing documents, or deleting content, while securities trading and transfers between accounts are not permitted even with approval.

Anthropic Launches Proactive Agent App Claude Duet

Anthropic has opened a research preview of Claude Duet, a standalone app that works as a proactive agent, handling tasks across connected apps, tracking email and calendar, and continuing to run in the cloud after the app is closed. The feature costs nothing extra but counts toward existing plan usage, and background work may cause users to hit limits sooner; it is currently invite-only and not yet available on Team and Enterprise plans. Claude Duet is powered by Claude Opus 5.5 and is available on iOS, Android, and the web, supporting Stripe unpaid invoice checks, Link and Shop Pay payments after user approval, as well as plugins and a cloud browser.

Anthropic Opens Claude Duet Research Preview: An Agentic App That Can Proactively Execute Tasks

Anthropic has opened the Claude Duet research preview, an agentic app built on Claude Opus 5.5 that can proactively advance tasks. It is now available on iOS, Android, and claude.ai for Pro and Max users in the United States, who must join a waitlist.

Claude Duet can invoke more than 6,000 connectors and plugins in the Claude Marketplace, and it follows the credential-handling approach of Claude Managed Agents, never directly touching users' passwords or login tokens.

Anthropic CEO Dario's Long Post Responds to Nine Criticisms from an External Safety Researcher

Anthropic CEO Dario Amodei published a long post responding to nine criticisms from external safety researcher Nathan Calvin, acknowledging that some of the examples were Anthropic's mistakes but disagreeing with the main thrust of the entire critique. He said Anthropic's strategy is "race to the top," that is, demonstrating responsible technology building at the frontier in order to raise standards across the entire industry; and he listed safety measures from the past year that he considers to have had commercial costs, including SB53 legislation, biosecurity protections, delaying the release of Mythos-class models, chip export controls, restricting sales of AI services to China-related companies, and committing 5% of company equity to a public-interest fund. He also acknowledged that the communication around points 7, 8, and 9 could have been better, and that the point 5 RSP revision is the most substantive point of dispute.
