Codex

One agent for everywhere you code—included in ChatGPT Plus, Pro, Business, Edu, and Enterprise plans.

Your new coding partner

Switch seamlessly between real-time collaboration and async delegation with Codex in all your tools.

Pair with Codex in your terminal or IDE

Starting from a prompt or spec, Codex navigates your repo to edit files, run commands, and execute tests. Ship new features, fix bugs, brainstorm solutions, or tackle whatever’s next with the Codex CLI and IDE extension—available in VSCode, Cursor, and Windsurf.

Delegate to Codex in the cloud

Codex runs in the background so you can stay in flow and get more done. It runs each task in an isolated sandbox with your repo and environment, generating code you can review, merge, or pull down to your computer to keep working.

Code on your phone

Kick off tasks from the ChatGPT mobile app, wherever inspiration strikes. Track progress, review PRs, and merge changes to continue building on the go.
