ChatGPT mobile app adds Codex support for cross-device collaboration

ChatGPT移动端支持Codex，实现跨设备协作

OpenAI Devs says the ChatGPT mobile app now supports Codex, letting users ask questions on mobile and continue the same conversation on desktop; the post does not disclose supported platforms, app versions, or rollout scope.

Why it matters: OpenAI Devs is authoritative and HKR-H/K/R pass, but the post only confirms mobile Codex access and handoff; platform, version, and rollout scope are not disclosed, so it sits at the featured threshold.

Take

OpenAI is trying to move developer context into the ChatGPT account layer, not make phone-based coding normal. The disclosed facts are narrow: ChatGPT mobile now supports Codex, users can ask on mobile, and continue the same thread on desktop. Supported platforms, app versions, rollout scope, and repo access are not disclosed. That matters because cross-device Q&A and an executable coding agent require very different permission models.

I do not buy the “leave your laptop at home” framing. GitHub Copilot still lives where the code lives: the IDE. Cursor’s grip comes from local project context. OpenAI’s play is the persistent conversation thread sitting above those tools. If mobile Codex only explains code, it is an entry-point patch. If it can touch repos, PRs, and CI, it starts pressuring IDE-side agents. The snippet only proves the first case.
