Anyone know if ChatGPT Codex (in the new ChatGPT desktop app) is a strict superset of ChatGPT Work? Liked if you're a software engineer who isn't intimidated by Git features is there any reason you'd ever want to switch to ChatGPT Work Mode?

Why it worked

Opens with a question, so the reader starts answering before they have decided to read.
Uses language that signals shared identity with a specific audience.
Ends on a question, which is the most reliable way to turn readers into repliers.
Short enough to read in full without expanding, which removes a step before the point lands.

The mechanics

Hook: Opens with a question
Structure: Hook → Invitation
Style: Conversational paragraphs at a steady pace.
Tone: plain, matter-of-fact

Written for: Engineers and technical teams
