What's included

Codex is OpenAI's coding agent. It starts from a goal or task, gathers context in the repository, takes action and delivers the result, including AI-assisted code review. It is available as a CLI for the terminal, an IDE extension, a desktop app (Windows, macOS and Linux, the latter in preview) and a cloud development environment in the browser, with support for long-running tasks, scheduled automations and notifications. Access is included in the ChatGPT Plus (US$20/month), Pro and Business subscriptions, with usage limits that vary by plan.
