Felix Rieseberg 谈 Cowork 架构：推理与 VM 迁移至云端
Simon Willison 博客引用 Anthropic 的 Felix Rieseberg 说明：旧版 Cowork 在云端做模型推理、在本地 VM 执行工具调用，用户不满本地 VM 的磁盘、电池和性能开销，以及合上笔记本就中断工作；新版将模型推理和 VM 都放到云端，每个会话拥有独立沙箱、不共享状态，需要访问用户设备文件时由桌面应用负责该工具调用。
AI推荐理由 Simon Willison 博客引用 Anthropic 的 Felix Rieseberg 对 Cowork 架构变更的说明：新版将模型推理与 VM 都放到云端，每个会话独立沙箱，设备文件访问由桌面应用负责，属于官方人员对产品架构调整的具体解释，信息明确。

> 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)
