Anthropic Cowork 改为云端架构：推理与沙箱上云，本地仅负责文件访问
Quoting Felix Rieseberg
Anthropic 把 Claude Cowork 的 VM 和推理都搬上云了，合盖不掉线、手机也能用，本地只管文件访问，架构讲得很清楚。
Anthropic 的 Felix Rieseberg 解释了 Claude Cowork 的新旧架构差异。旧版把模型推理放在云端，但在用户电脑上运行 Anthropic 提供的本地 VM，带来磁盘、电池和性能开销，且合上笔记本后任务即中断。新版将推理和 VM 全部迁到云端，每个会话拥有独立沙箱，不与其他会话共享状态。当 VM 需要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，同时支持手机上使用 Cowork。
Quoting Felix Rieseberg
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) — Felix Rieseberg , Anthropic, see also this help page Tags: claude-cowork , anthropic , claude , generative-ai , ai , general-agents , llms
