Overview
Codex is OpenAI's software engineering agent. It plans and builds features, fixes bugs, refactors code, writes tests, and reviews pull requests, and it can run several agents in parallel on separate tasks.
The same agent works in the Codex app, the open-source Codex CLI, IDE extensions, Codex cloud for long-running background tasks, and inside ChatGPT. Code review can be turned on for a repository so Codex checks each pull request.
Codex is included with ChatGPT Plus, Pro, Business, and Enterprise plans.
