Run OpenAI Codex on a machine of your own
Codex is OpenAI's coding agent CLI. It is installed on every machine as part of the build, in the same session manager as the other agents.
You bring your own OpenAI credentials; they stay on your machine.
How it arrives
- On the machine
- Installed as part of the build
- How you run it
- A command line tool — you run it in a terminal tab
We did not write OpenAI Codex. It is openai/codex. We install it on every machine and put it behind the login.
Unattended runs
The machine is a real VM that keeps running when you close the tab. A process you start does not stop because your laptop slept, your train went into a tunnel, or you switched to your phone.
Side by side with the others
Claude Code, OpenCode, Gemini CLI and Kimi CLI are on the same box. Running the same task through two agents and comparing the diffs is a second tab.
Questions
- Do I need an OpenAI account?
- Yes. The CLI is installed; the account it uses is yours and its credentials stay on the machine.
Once you have one
It comes with the machine
