Claude Cowork 全面迁移至云端
Anthropic 的 Felix Rieseberg 说明了 Claude Cowork 的架构调整：旧版在云端做模型推理，但把工具调用放到随桌面端分发的 Anthropic 虚拟机上执行；他称加入该虚拟机是出于能力、安全和安保考虑，只映射用户明确加入会话的数据。新版则把模型推理和虚拟机都放进云端，每个会话拥有独立沙箱、互不共享状态；当虚拟机需要用户设备上的文件时，由桌面应用负责该文件访问工具调用。Rieseberg 表示这解决了用户抱怨的本地虚拟机占用磁盘、耗电和影响性能，以及合上笔记本工作就中断等问题。
为什么重要：这一调整显示智能体厂商正把执行环境从本地转向云端沙箱，以便跨设备维持长时间运行的任务。

The "old" version of Cowork runs model inference in the cloud, executing tool calls in an Anthropic-provided VM we shipped to your computer. We added the VM for capability, safety, and security reasons - mapping in just the data you explicitly added to your session. People loved what they were able to do with Claude but didn't love the disk, battery, and performance cost of running the VM locally. Also, people didn't love that closing your laptop means the work stops.
The "new" version of Cowork runs model inference and the VM in the cloud. Each session gets its own sandbox, not sharing state with other sessions. When the VM needs something on the users' device (like a file), the desktop app is responsible for that file access tool call. [...]
We think this solves a lot of problems we've heard about (like using Cowork from a phone, keeping work running, or getting all the same power without losing battery to the VM)
