Anthropic Cowork 改为云端运行模型推理与 VM
Quoting Felix Rieseberg
Anthropic 工程师 Felix Rieseberg 说明 Cowork 的新旧架构差异：旧版在云端推理、在用户电脑上运行本地 VM，磁盘、电池和性能开销大，合上笔记本工作就停止。新版把模型推理和 VM 都移到云端，每个会话有独立沙盒，桌面应用只负责文件访问等需要本机设备的工具调用，官方认为这解决了手机使用、保持工作运行和电池消耗等问题。
作者引用 Anthropic 工程师的说明，解释了 Cowork 从本地 VM 改为云端沙盒的架构变化和动机，读者可了解其取舍。
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)
