OpenAI Codex arrives on ChatGPT mobile app to let developers manage coding tasks remotely

OpenAI's Codex is now in the ChatGPT mobile app

OpenAI is going to let users access Codex, its desktop AI tool that can write code and use apps on your computer, from the ChatGPT app on your phone. Following the surge in popularity for Anthropic's Claude Code, OpenAI has been working quickly to try and catch up, including by cutting back on "side quests," shutting down projects like the Sora video-generation tool, and focusing on growing its enterprise business. The company's push included the recently released major update for Codex that lets it operate apps on macOS -- a potentially major step as part of its ambitions to make a desktop "superapp." Codex in the ChatGPT mobile app lets you use your phone to tell Codex on your computer to work on a task. With your phone, you can "work across all of your threads, review outputs, approve commands, change models, or start something new" in Codex, according to a blog post. "Your files, credentials, permissions, and local setup stay on the machine where Codex is operating, while updates flow back to your phone in real time, including screenshots, terminal output, diffs, test results, and approvals." The feature is rolling out now as a preview on iOS and Android for all ChatGPT plans, including the free plan and the more affordable Go plan.

Your Phone Can Now Remotely Control ChatGPT's Codex Coding Tools

OpenAI is working hard to improve its coding tools to compete with rivals such as Anthropic's Claude, and a new feature makes it easier to use Codex on the move without sacrificing powerful results. Codex is now available through the ChatGPT mobile app for Android and iOS, although you won't be able to program anything directly on your device. Instead, it's used as a remote control for any environment you use for coding projects, such as a dedicated home computer or your laptop. OpenAI says, "From your phone, you can work across all of your threads, review outputs, approve commands, change models, or start something new." As it connects to your main environment, it will have access to all files, credentials, and other settings you have configured, making it easier to make changes. These new mobile app features let you switch what your computer is doing even when you're away, with OpenAI sharing examples of how you can keep your system running while you're on a commute or running errands out of the house. If Codex completes a task or needs prompting on what to do next, you no longer have to wait until you return for it to restart work. You'll find this new option in the latest version of the ChatGPT mobile app, but OpenAI says this is a "preview," suggesting there may be future changes to the feature. The feature is available across plans, including free versions of ChatGPT. Over four million people use its Codex tools every week, according to OpenAI. OpenAI recently told all Mac users to update their apps, including ChatGPT and Codex, after a software supply chain attack compromised several employee devices. It happened through open-source software called Tanstack, with an attacker publishing 84 malicious versions on Monday. Security researchers spotted the software and removed the files within 20 minutes of upload. Disclosure: Ziff Davis, PCMag's parent company, filed a lawsuit against OpenAI in April 2025, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.

OpenAI Codex is coming to mobile so you can build apps on the go

Mobile support currently works with macOS-based Codex sessions, but Windows compatibility is already on the roadmap. OpenAI is making ChatGPT a much more useful tool for developers on the go. The company has officially rolled out Codex, its AI coding assistant, inside the ChatGPT mobile app, giving users the ability to track and manage coding tasks right from their phones. The new mobile integration, now in preview on both Android and iOS, lets users interact with Codex sessions running on their machines remotely. Android Authority first spotted evidence of this upgrade earlier this month. From the ChatGPT app, you can review generated code, approve commands, switch AI models, start new tasks, and monitor ongoing workflows in real time. OpenAI says Codex now has more than four million weekly users, and clearly the company wants to help make those workflows feel less desktop-bound. In a blog post, OpenAI described the feature as a way to "stay in the loop from anywhere," especially for quick approvals or check-ins that keep projects from stalling. That said, your actual files, credentials, and development environment remain on the host machine that Codex is running on, with the phone acting more like a remote control center. Screenshots, terminal output, diffs, and test results flow back into the mobile app. For now, the mobile feature works with Codex on macOS systems, though OpenAI says Windows support is coming soon. OpenAI has been rapidly expanding Codex over the last year, first launching it as a cloud-based coding agent capable of fixing bugs, answering questions on codebases, and suggesting pull requests. Most recently, the company added the ability for Codex to interact directly with macOS apps and to multitask across long-running projects. The release comes as Anthropic's Claude Code has gained serious traction among developers, and OpenAI looks determined to not give up any ground in the increasingly crowded AI coding space.

You can access Codex on your phone now

Why it matters: OpenAI is trying to make Codex cheaper and easier to use as it battles Anthropic for developers and enterprise customers. Driving the news: Mobile access to Codex will let users review outputs, make approvals and start new tasks from mobile. * Start something from a computer at home and then go out to the coffee shop and approve the final output over your matcha. Zoom in: Additional updates will allow models to be used more seamlessly within certain industries, including: * Support for HIPAA-compliant use of Codex in local environments for ChatGPT, allowing hospitals and healthcare organizations to further adopt AI tools. * Developer tools like automatic prompt checking or code validation. Reality check: Approving agents on your phone could lead to greater risk for errors when users are multi-tasking on a small screen. Yes, but: increasing Codex usage also means consumers will be using more compute, the most precious resource of the AI labs. OpenAI's strategy has been defined by compute subsidies to increase usage. Zoom out: The announcement comes one day after CEO Sam Altman announced that any companies who switches to Codex will get two months worth of free usage. * That came after reports of Anthropic raising prices. * Anthropic's coding tool, Claude Code, is available on mobile through what it calls remote control sessions. Between the lines: This has become a familiar pattern between the rivals. * Anthropic lifts prices due to surging demand, OpenAI lowers them in hopes of taking market share. The bottom line: OpenAI wants its coding tools to be more accessible and widely adopted.

OpenAI brings Codex to mobile devices, adds more customization features - SiliconANGLE

OpenAI brings Codex to mobile devices, adds more customization features OpenAI Group PBC today made its Codex programming assistant available on mobile devices. The service is accessible through ChatGPT's iOS and Android clients. It's rolling out about eight months after Anthropic PBC made Claude Code, its competing programming assistant, available on handsets. OpenAI says that the newly added mobile access can significantly speed up some software development tasks. Furthermore, it reduces inference costs in the process. GPT-5.5, the large language model that powers Codex, can complete hours-long programming tasks. Such workflows occasionally require developers to provide the AI with guidance. If Codex identifies two different ways to rewrite a piece of legacy code, it might ask the user to specify which method should be applied. Developer input is also needed when the service requires permission to make a high-stake project change. Until now, users who launched a long-running task and stepped away from their computers had no way of giving Codex guidance. That meant a task could be held up for hours. The new mobile support removes the need for Codex to wait until the user regains access to their desktop, which avoids unnecessary project delays. There are situations where Codex doesn't strictly require user guidance to proceed with a task, but could still benefit from technical pointers. For example, developers might wish to interrupt the service if it starts implementing a software module in a non-optimal manner. Now that Codex is available via mobile devices, users can interrupt it even if they don't have access to their desktops. That avoids the unnecessary token usage associated with erroneously completed programming workflows. Reducing token usage, in turn, lowers software teams' ChatGPT bills. OpenAI is rolling out the mobile support alongside two other new Codex capabilities called Hooks and Remote SSH. Hooks enables customers to customize the programming assistant with scripts. A cybersecurity professional, for example, could write a script that blocks developers' Codex prompts if they contain sensitive company information. The legal team, in turn, might use Hooks to log Codex messages for regulatory compliance purposes. Scripts created using the tool can process not only prompts but also the programming assistant's responses. In particular, developers can use the feature to customize Codex's output for each project. Software teams often write, test and store code in cloud-based environments rather than on their local machines. That arrangement makes it easier for administrators to manage cybersecurity settings. Remote SSH, the feature that is rolling out alongside Hooks, enables Codex to connect to remote development environments via an encrypted network link.

The developer who never clocks out: OpenAI wants Codex in your pocket

Developer anxiety is a form of anxiety that is triggered when you leave your computer workstation. There is an operation currently happening and activity going on inside of Codex that you do not know if the work you are doing is going to hang, reach a decision tree or even just go wrong while you're not at your office. Open AI claims that they have addressed this issue with Codex. Also read: Claude Mythos and GPT-5.5 have confirmed what researchers feared most about AI and cybersecurity Starting from May 14, Codex will be available via the Chat GPT mobile app for iOS and Android. This is not a mobile version or limited dashboard; Open AI claims that it is an entire mobile experience that enables you to connect to and work on any Codex-enabled device (e.g. laptop, Mac Mini, remote server) and to continue your work exactly where you left off. The live state will be imported from the desktop computer; therefore, the active threads will be preserved, and all approvals, plugins, and project context will also travel with you. Also read: Figure AI's Helix-02 humanoid robots is pulling full 8-hour factory shifts without human help Once you understand how Codex works, it makes sense. Long-running, agentic processes do not always operate on a fire and forget basis. They will encounter points where human intervention is required. Without mobile access, that means work stalls the moment you leave your desk. With it, you catch the decision point on your commute, make the call, and arrive at the office to find the task already done. OpenAI has used examples to demonstrate how different types of situations might unfold under various conditions. Imagine you have just finished enjoying your favorite cup of coffee and realize that you need some help with debugging a project. Using Codex, you can have everything you need, including files necessary for reproducing a problem in a browser window, performing a set of tests, and finding your way to resolution all before you are actually able to sit at your desk. Another example might be an upcoming important customer call. Before speaking with the customer, you can use Codex to build out a brief using the following data: your most recent messages from Slack, your most recent emails, and any associated documentation. You then feel confident that you are prepared for the call. Technically speaking, the existence of a secured relay layer affords you the ability to continue using the trusted machines, but without exposing those machines to the public internet. Your files, credentials, and local environment reside solely on the machine, while only the outputs (e.g., screenshots, terminal logs, test runs) would be sent to your device. Currently, there are over 4 million developers who use Codex on a weekly basis. OpenAI believes those who share a passion for their work would not want to lose that passion simply because they now reside in a different physical location.
