one of the best features of ChatGPT Work is that it runs in the cloud, meaning that it works from mobile, with your laptop closed. kinda crazy how long the main way to get the magic of agents has been while leaving your laptop cracked open!

@simonw @gdb Valid feedback! and this is top of mind to simplify. It’s correct that Work on Web & App runs on cloud whilst on Desktop App it runs locally.

@gdb This right here is the key confusion! In the ChatGPT mobile app, Work runs in the cloud - but in the ChatGPT desktop app we've been told that Work is just a reskinned Codex, and Codex in the desktop app runs on the device

@reach_vb @gdb I've started thinking of ChatGPT Mobile's "Work" as ChatGPT Code Interpreter with most of the safeties turned off

🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣 Greg, do you seriously think people are stupid? Changing the power settings so the system doesn't sleep on a closed lid takes two damn minutes. Tailscale completely handles streaming the model from your laptop to your smartphone. Voila! Your agent is always with you - without any Gregs and their clouds. #keep4o #OpenSource4o
