About Codex CLI
Codex CLI is a terminal coding agent from OpenAI, with its source code published on GitHub. It works alongside the Codex IDE extension and the cloud version of Codex.
What it does
Codex CLI reads and edits code in your project and runs commands from the terminal. It uses the same agent family as the Codex IDE extension and cloud agent, so you can move work between them. The docs also cover skills, permissions and configuration for controlling how the agent behaves.
Key features
- Read, edit and run code from your terminal
- Also available as an IDE extension and a cloud agent
- Source code published under the Apache 2.0 licence
- Skills and permission settings for agent behavior
Who it's for
Developers and engineering teams who work in the terminal and want an agent they can inspect and configure. It is also suited to people who already use ChatGPT and Codex.
Pricing and good to know
The CLI source is open source under Apache 2.0. Access to Codex features is tied to ChatGPT plans, and the docs list plan details and usage limits, which are not in the text available here. Check those limits before relying on the agent for a large job.
