About
OpenAI Codex is a cloud-hosted coding agent that operates on a sandboxed copy of a repository, letting it read files, run tests and make changes in parallel with your own work. Tasks are submitted as written instructions and Codex produces a pull request or diff for review. Because it runs remotely no local compute is required and multiple tasks can proceed at the same time. It is available through ChatGPT and through the OpenAI API for developers who want to embed it in their own tools.
Features
- Sandboxed cloud execution of coding tasks
- Parallel task execution across multiple branches
- Pull request and diff output for review
- Natural-language task submission
- API access for custom integrations
Best for
- Running coding tasks in parallel without tying up a local machine
- Teams that want a human-review step before any change is merged
- Delegating tasks by writing natural-language instructions
