Codex integrated into ChatGPT mobile apps, bringing code generation to iOS and Android

OpenAI said on May 14 that Codex is now available in preview inside the ChatGPT mobile app, extending its coding agent to iPhone and Android users who want to monitor and steer software tasks away from their desks. The company described the feature as a “fully-featured mobile experience” that lets users review outputs, approve commands, change models and start new work from a phone while Codex continues running on another machine. OpenAI said the rollout is underway in supported regions on iOS and Android. The company’s help center says the feature is rolling out across ChatGPT plans, including Free and Go, in supported regions. ### Which phones and plans are getting it first? OpenAI’s May 14 product post says Codex in the ChatGPT mobile app is arriving on iOS and Android as a preview. The company said users can connect the phone app to a machine where Codex is already running, including a laptop, a dedicated Mac mini or a managed remote environment. (openai.com) The Help Center release notes say the mobile rollout covers “all plans, including Free and Go,” in supported regions. A separate Help Center article on Codex access says Codex is included with ChatGPT Plus, Pro, Business and Enterprise/Edu plans, which suggests plan availability depends on the specific Codex setup and account type a user has.

OpenAI said the phone app can surface the live state of the environment where Codex is operating, including project context, approvals, plugins and active threads. The company said updates flow back to the phone in real time, including screenshots, terminal output, diffs, test results and approval requests. (help.openai.com) The May 14 community announcement says users can start new work, review outputs, steer execution and approve next steps from the ChatGPT mobile app while Codex keeps running on a laptop, Mac mini or devbox. OpenAI’s product post said files, credentials, permissions and local setup remain on the underlying machine rather than moving onto the phone itself. (openai.com) ### Does the mobile app replace the desktop Codex setup? OpenAI said this is not just remote control for a single task. The company said users can move across threads, review outputs, switch models and add new work from the phone while the actual coding environment remains on the connected host machine. The Codex changelog says the current mobile setup works by connecting the ChatGPT mobile app to a Mac running the Codex app. (community.openai.com) OpenAI’s Help Center also tells users to update both the ChatGPT mobile app and the Codex app on macOS to try the feature. ### Why is OpenAI emphasizing approvals and long-running tasks? OpenAI said “a new rhythm for collaboration is emerging” as coding agents take on longer-running work, and said quick check-ins can prevent rework or help Codex continue with the right context. (openai.com) The company said the mobile app is meant to let users answer a question, review findings, change direction or approve what comes next without returning to a desk. (developers.openai.com) OpenAI also used a scale figure to frame the launch. The company said more than 4 million people now use Codex every week. ### What is still missing from the rollout? OpenAI’s May 14 community post says support for connecting the phone to the Codex app on Windows is “coming soon.” The current documentation and changelog describe the mobile connection in terms of a Mac host running the Codex app, along with remote environments and devboxes. (openai.com) The next step for users is procedural rather than theoretical. OpenAI’s release notes say people who want the feature should update the ChatGPT mobile app and the Codex macOS app, and the company’s changelog lists May 14, 2026 as the date the mobile capability was added.
