`Codex` now works through the `ChatGPT` mobile app

You can watch, steer, and approve coding jobs from your phone while they run on other devices or remote environments. That makes long-running agent work less desktop-bound and immediately more usable.

• —ChatGPT mobile now supports real-time monitoring of Codex tasks, so jobs no longer need a laptop babysitter.
• —Approval and steering happen across devices, which matters when agent runs touch prod-like or remote environments.
• —The upgrade is operational rather than model-level, but it removes friction from longer coding sessions and async workflows.
