Summary & Key Takeaways ​

• Anthropic's Cowork product has updated its architecture.
• Model inference and the execution VM now run entirely in the cloud.
• The previous version ran the VM locally, causing performance and battery drain.
• This shift addresses issues like work stopping when a laptop closes.
• The desktop app now handles local file access via tool calls.
• The change aims to improve user experience and enable mobile use.

Our Commentary ​

This is a fascinating architectural pivot for an AI agent. Running a VM locally for tool calls always felt like a heavy lift for users, so moving it to the cloud makes a lot of sense for performance and battery life. I'm curious about the security implications of cloud-based VMs for sensitive local data, even with the desktop app mediating access.
