OpenAI, the global artificial intelligence company behind ChatGPT, known for developing advanced generative AI systems, has expanded its AI coding agent, Codex, to mobile devices by integrating it into the ChatGPT app for iOS and Android, enabling users to monitor and control coding tasks remotely from their phones.
The update, announced on May 14–15, 2026, extends Codex beyond desktop environments and allows developers to interact with ongoing software development work while the system runs on connected computers or cloud-based development environments.
The move is part of OpenAI’s effort to make its coding tools more flexible and accessible across devices. Codex was originally introduced in February 2026 as a desktop-focused AI coding agent designed to assist software developers with tasks such as writing code, debugging programs, reviewing repositories, and generating pull requests.
It operates as a semi-autonomous system capable of handling complex engineering tasks over extended periods with minimal human input.
With the new mobile integration, users can now track task progress, view logs and outputs, and approve or reject code changes in real time without needing access to their primary development machine.
The mobile app does not run Codex directly; instead, it serves as a control interface connected to remote or local systems where Codex executes its tasks.
OpenAI described the update as part of a broader shift toward asynchronous software development workflows, in which developers supervise AI systems rather than manually executing every step of the coding process.
“Codex is now in the ChatGPT mobile app so you can stay in the loop from anywhere while Codex gets work done across your laptops, devboxes, or remote environments,” OpenAI said in a statement published on its official website.
The company added that the feature is intended to allow developers to “stay connected to active work from anywhere,” while still maintaining oversight of automated coding operations and outputs.
Industry observers say the move reflects increasing competition in the AI software development tools market, as companies race to build more autonomous coding agents capable of handling longer-running engineering tasks with intermittent human supervision.
Analysts also note that the mobile expansion strengthens OpenAI’s position in the developer tools framework by making AI-assisted coding more persistent, collaborative, and accessible across multiple devices and environments.
The rollout comes amid broader industry adoption of AI coding agents, which are increasingly used to manage complex engineering workflows that require periodic review rather than continuous manual coding. These tools are becoming central to modern software development practices.
OpenAI did not announce any additional technical changes beyond the mobile integration in the ChatGPT app, but said Codex will continue to evolve as part of its broader AI development plans.
