PRODUCT OVERVIEW

What is Codex?

Codex is OpenAI's AI coding partner, built to take on real engineering work such as hard-to-find bugs, complex refactors and new features. It runs many agents in parallel, using computer and browser tools to verify work until requirements are met, while you follow progress, steer agents and review results in one place. Codex works across ChatGPT, an IDE extension, a command-line interface and reusable cloud environments, so tasks keep moving when you close your laptop and can be resumed from another device. It also automatically reviews pull requests, surfaces findings and answers questions, and plugins connect tools such as GitHub, Slack, Gmail, Google Drive, Figma, Notion and Supabase. Codex is included in ChatGPT Plus, Pro and Business plans, with Business adding a shared workspace and admin controls.
