Claim◆Article
The difference between ChatGPT Work on mobile versus the desktop app is spectacularly unintuitive — mobile Work mode simply grants the Code Interpreter unrestricted internet access rather than providing agentic capabilities.
The author notes that ChatGPT Work on mobile is effectively just adding internet access to the Code Interpreter, unlike the desktop version which is a full agentic interface — and points out this distinction is poorly communicated to users. ✦ AI generated

I think the difference between ChatGPT Work on a mobile device and ChatGPT Work inside the desktop app (where it's effectively a less intimidating skin on top of Codex) is spectacularly unintuitive. Short version: if you flip ChatGPT mobile from "Chat" to "Work" mode you get a version where its Code Interpreter container is no longer restricted from accessing the internet!
