# ChatGPT Agent Is Gone: How to Choose ChatGPT Work vs Codex > Source: > Published: 2026-08-15 18:41:30+00:00 ChatGPT agent is no longer available. Reinstalling the desktop app will not restore the old surface. OpenAI now separates longer non-code work, repository work, and browser authority across different tools. Use **ChatGPT Work** for research, analysis, documents, spreadsheets, presentations, reports, and Sites. Use **Codex** for repository edits, tests, commands, code review, and software-development workflows. Use the **desktop built-in browser** when the user can sign in and authorize specific tabs. Use the **Codex Chrome extension** when the task needs an existing Chrome profile, cookies, sessions, or extensions. The cloud browser is for supported public pages and should stop at sign-in or payment. This is a product transition, not a local installation failure. OpenAI's current guidance directs longer multi-step work and finished deliverables to ChatGPT Work while keeping Codex as the software-development surface. If Work is missing, check plan eligibility, staged rollout, workspace role, model availability, and organizational policy before reinstalling anything. Ask what the workflow must produce: The name of the old tool is less important than the destination artifact and authority boundary. Do not simply replace the words `ChatGPT agent` with `ChatGPT Work` . Rewrite the task contract to name: This prevents an old prompt from silently carrying browser, credential, payment, or filesystem assumptions into a different execution surface. Cloud browser, the desktop built-in browser, the Chrome extension, connected apps, local files, and repository tools have different authority.
