Questions

Does Codex run unmodified?

Yes. It installs with its maker’s own command and runs as it would on an arm64 Linux machine.

Can Codex damage my computer?

No. It works inside your outpost, a separate Linux machine in the tab, and cannot reach your computer’s files.

What does it cost?

The outpost is free. You use your own account with the agent’s maker for the model.
