Codex now runs in the ChatGPT mobile app, letting you monitor, steer, and approve long-running coding tasks across laptops, devboxes, and remote environments in real time.
Key Takeaways
A secure relay layer keeps trusted machines reachable across devices without public internet exposure; files, credentials, and permissions stay on the host machine.
Remote SSH is now generally available, letting Codex connect directly into managed enterprise environments detected from SSH config.
Programmatic access tokens (Enterprise and Business only) enable scoped credentials for CI pipelines, release workflows, and internal automations.
Hooks are GA: scan prompts for secrets, run validators, log conversations, or customize behavior per repo and directory.
HIPAA-compliant Codex use is supported for eligible ChatGPT Enterprise workspaces in local environments (CLI, IDE, App).
Hacker News Comment Review
Commenters noted Codex on the free plan is a genuine surprise – no payment required to start, though the tradeoff is interactions feeding training data.
Practical skepticism emerged around mobile-driven coding: one builder who tunneled into Codex for months found less keyboard control leads to worse steering, more tech debt, and code churn.
Linux users and Codex CLI operators feel left out – the mobile relay works only with the Codex desktop app (macOS/Windows), not CLI or Linux machines with GPU rigs.
Notable Comments
@jumploops: Found mobile Codex sessions produce worse results in practice – reduced steering from phone causes measurable code churn compared to keyboard-driven sessions.
@boodleboodle: Asks whether Codex CLI will get relay support for remote Linux/Nvidia GPU machines, a gap the announcement does not address.
