Anthropic 的 Cowork 改为在云端运行模型推理与 VM

A quote from Felix Rieseberg

AI 导读

Anthropic 的 Felix Rieseberg 表示，新版 Cowork 把模型推理和 VM 都放到云端运行，每个会话拥有独立沙箱、不与其他会话共享状态。旧版在云端做模型推理、但把 Anthropic 提供的 VM 装到用户电脑上执行工具调用，用户不满其磁盘、电量和性能开销，以及合上笔记本工作就中断。当 VM 需要访问用户设备上的文件时，由桌面应用负责该文件访问的工具调用。

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)
