ChatGPT Agent Is Gone: How to Choose ChatGPT Work vs Codex

OpenAI has retired the ChatGPT agent, splitting its capabilities across ChatGPT Work for research and document tasks and Codex for software development. The transition affects browser authority and credential handling, with guidance for users to adapt workflows to the new tools.

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.
