Anthropic 向所有付费计划开放 Claude Cowork，测试版标签仍然保留

Why it matters

Cowork's expansion gives Anthropic a much larger paid audience for persistent agents, while the remaining beta label and desktop dependencies show how far cloud delegation still is from replacing local work.

On August 18, Anthropic, founded by siblings Dario Amodei and Daniela Amodei, said Claude Cowork was available on mobile and web across all paid plans, completing a rollout that began with its most expensive individual subscription.

Claude on X

For the cofounders, the wider release pushes Claude further from its origins as a chatbot. In a 2023 interview with Stripe, Daniela Amodei said Anthropic wanted "humans to be at the center" as AI systems became more capable. Anthropic says Cowork lets users hand Claude tasks involving connected files, email, calendars, messaging apps, the web and other tools; Claude can continue working, request decisions and hold completed work for review and approval.

Anthropic's documentation describes web and mobile Cowork as a beta expansion that began with Max subscribers before moving to other paid plans. The update attaches Cowork sessions and files to Claude accounts, allowing users to move the same task between desktop, web and mobile.

The August 18 announcement brings that design to Pro, Max and Team subscribers. Enterprise users can access web and mobile Cowork when an administrator enables it, according to Anthropic's current documentation. The expansion matters most at the bottom of the pricing ladder: Claude Pro costs $20 a month, compared with $100 or $200 for the two Max tiers.

Cowork leaves the laptop

Claude Cowork is built for assignments that require several steps rather than a single generated response. Anthropic presents examples including reconciling spreadsheet data, reviewing groups of contracts, assembling recurring reports and producing client materials from connected documents and communications.

On web and mobile, Cowork's agent loop and code execution run on Anthropic's servers. Sessions and files are stored with the user's Claude account, which lets a task continue after the laptop that started it has been closed. Scheduled tasks can also run without any user device remaining online.

That changes where Anthropic can compete for knowledge work. A desktop-only agent asks users to stay near the machine that owns the session. A cloud session can be started at a desk, checked from a phone and resumed in a browser. The product starts to resemble an assigned worker with an inbox of tasks rather than another tab waiting for a prompt.

Anthropic has not disclosed a Cowork user count or revenue contribution, so the size of the rollout is not public. The product's cross-device access points toward recurring preparation and assembly work between meetings, rather than limiting its agent push to coding.

Desktop remains the fullest version of Cowork. Local folders, local connectors, browser control and computer use from a web or mobile session still depend on the Claude Desktop app running on the connected computer. If that app closes, the cloud task continues but loses access to the device. Anthropic's current feature table lists live artifacts as available only on desktop.

Availability moved faster than the documentation

Anthropic's short announcement says Cowork is available on mobile and web for all paid plans. Its help center adds several qualifications.

The main access page describes web and mobile Cowork as a beta for Pro, Max and Team users, with Enterprise availability controlled by administrators. A separate architecture overview, which Anthropic labels as updated more than a week ago, still says Pro access will roll out over several weeks. Anthropic's safety documentation carries similar staggered-rollout language even as it also says Cowork is available to paid plans across desktop, web and mobile.

The conflict appears to be documentation lag around a rollout that reached its final subscription tier, rather than a change in Cowork's beta status. Paid availability is broad. General availability is not what Anthropic's current support pages claim.

That distinction matters for an agent entrusted with files, applications and unattended work. Web and mobile access improves distribution immediately, but users are still adopting a cloud execution system Anthropic labels as unfinished.

The permissions now travel too

Cowork can read documents, browse websites, run code and act through connected applications. Anthropic isolates each cloud session in a temporary sandbox that is removed when the session ends. The sandbox cannot reach a user's home or corporate network by default, and connector credentials remain outside it.

Isolation does not remove the risk created by the permissions users grant. Anthropic warns that malicious instructions embedded in an email, website or document can attempt to redirect Claude through a prompt-injection attack. The risk increases when the same session can both read untrusted material and take consequential actions.

Anthropic requires explicit approval before Cowork permanently deletes a file and offers manual and automatic approval modes. Its guidance recommends manual oversight for sensitive accounts, unfamiliar tools, purchases and messages. Computer control deserves particular care because Claude interacts directly with the screen rather than operating behind the cloud code sandbox.

The Amodei siblings' bet is that delegation will become a normal interface for Claude, with chat reserved for questions and Cowork used for assignments. Putting the agent on the $20 plan and letting its tasks follow users between devices gives Anthropic a larger test of that premise. The harder work begins once those users connect the files, inboxes and applications that make Cowork useful enough to keep.
