OpenAI Codex
Delegate software tasks to coding agents across the Codex app, CLI, web, and IDE workflows, with access tied to eligible ChatGPT plans.
Key Features
- Assign coding tasks to agents working with a repository and inspect the resulting changes.
- Use Codex through supported app, web, CLI, and IDE experiences.
- Run parallel or longer coding tasks with plan-specific usage and organizational controls.
Target Demographics
Developers and teams that want agents to handle repository tasks, bug fixes, tests, or refactors while reviewing changes in a dedicated coding workflow.
Our Take
Codex is most useful for work that can be expressed as a bounded engineering task and validated against the repository. It is included with eligible ChatGPT plans, but usage limits vary; an agent’s completed patch is still a candidate change that needs tests and human review.
Pros
- Supports multi-step coding work beyond inline suggestions.
- Access is bundled with eligible ChatGPT plans, so existing subscribers may not need a separate coding subscription.
Cons
- Usage and rate limits depend on the ChatGPT plan and can change.
- Agent-generated code must be reviewed, tested, and checked for security and compatibility before merge.
Pricing
Codex is included with eligible ChatGPT Plus, Pro, Business, Enterprise, and Edu plans; usage amounts and team controls differ. Check the current Codex and ChatGPT plan pages rather than treating access as unlimited.
