An undocumented Codex 'Remote Control' feature lets you manage GPU cluster experiments from your phone:
- Run codex remote-control start on the server
- Run codex remote-control pair to get pairing codes
- In the app: Remote → Add connection → Pair manually, enter the code
The author, who runs a GPU slurm cluster, uses it daily to manage autoresearch experiments and training runs — a hidden mobile path beyond ChatGPT Desktop's SSH support.
