Felix Rieseberg 说明 Cowork 新版把推理和虚拟机放到云端
Quoting Felix Rieseberg
Anthropic 的 Felix Rieseberg 说明，新版 Cowork 把模型推理和虚拟机都放到云端，每个会话使用互不共享状态的独立沙箱。旧版只在云端做推理，工具调用则在发到用户电脑上的 Anthropic 虚拟机里执行，因此有磁盘、电池和性能开销，合上笔记本后工作也会停止。

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)
