Summary
ChatGPT Becomes an AI OS: Chat, Codex and the New Work Agent
OpenAI has reorganised ChatGPT around three surfaces inside a single connected desktop app: Chat for questions, Codex for development, and a brand-new agent called ChatGPT Work that takes on long-running projects and connects to the apps you already use. The same layout is coming to web and mobile so workflows stay in sync across devices. It's a one-minute rundown, not a walkthrough — treat it as a signal of where OpenAI is pointing the product rather than a setup guide.

Key Takeaways
- Three surfaces, one app. Chat, Codex and ChatGPT Work now live inside one connected desktop app rather than as separate products.
- ChatGPT Work is the agent piece. It's described as taking on long-running projects and connecting to the apps you already use — the execution layer, as opposed to Chat's question-and-answer role.
- Codex stays the developer surface — it isn't replaced by Work, it sits alongside it.
- Cross-device sync. The same structure is rolling out to web and mobile, so a workflow started on desktop continues elsewhere.
- A cloud browser with 100+ app plugins, with computer use as the fallback when no native plugin exists — the same "plugin first, click the UI second" pattern other agent platforms have converged on.
- Example workflow shown: a scheduled 6 a.m. "AI chief of staff" run that reviews task lists, project ideas, team chats and calendar, then reports what needs attention, what's blocked and what can wait.
The claims here are the creator's summary of an OpenAI announcement, and the video shows no configuration or commands. Before you rebuild a workflow around ChatGPT Work, check the feature list and availability on OpenAI's own release notes — agent surfaces of this kind commonly ship to a subset of plans first.
