OpenAI is continuously upgrading its platforms for both users and developers.
In its latest update, the company has added Codex support to the ChatGPT mobile app.
This new feature allows developers to manage coding tasks directly from their smartphones.
The rollout is currently in preview for Android and iPhone users in supported regions.
With this update, developers can stay connected to their coding work even when they are away from their computers.
What Developers Can Do with Codex on Mobile
The mobile version of Codex is designed to make remote coding easier and more flexible.
Developers can now handle several tasks directly from the ChatGPT app.
They can:
Review code outputs
Approve or reject commands
Switch between models
Monitor active coding threads
Start new development tasks
This means important coding work no longer needs to wait until a developer is back at their desk.
How Codex Connects Your Devices
According to OpenAI, Codex can connect with multiple systems where it is already running, such as:
Laptops
Mac mini systems
Remote development environments
Dev boxes
Your files, credentials, and local setups remain secure on your main device.
The mobile app only receives live updates like:
Code changes
Test results
Screenshots
Terminal outputs
OpenAI says this works through a secure relay system that keeps devices connected without exposing them directly to the public internet.
Designed for Real-World Developer Needs
The goal of this update is to support developers who are often on the move.
For example, developers can:
Approve code changes while traveling
Check bug fixes remotely
Review summaries before meetings
This makes it easier to manage coding workflows even outside traditional office setups.
OpenAI Expands Codex for Enterprise Users
Along with mobile support, OpenAI has also introduced new features for enterprise users and large development teams.
These include:
Programming access tokens to automate workflows
Tools for internal development operations
Support for release pipelines
“Hooks” to customize Codex behavior for specific projects
These updates also help with tasks like logging conversations, scanning for security issues, and validating development workflows.
Growing Competition in AI Coding Tools
The AI coding space is becoming increasingly competitive. Companies like OpenAI and Anthropic are rapidly improving their tools.
Earlier, Anthropic introduced Remote Control for Claude Code, while OpenAI has added features like background task execution and browser-based functionality to Codex.
Both companies are now focusing on building AI systems that can handle more independent and long-running tasks.
Availability of Codex in ChatGPT Mobile App
OpenAI has confirmed that Codex support is rolling out in preview for Android and iOS users.
The feature will be available across all regions where ChatGPT is supported, including Free and Go plans.
To access it, users need to update:
ChatGPT mobile app
Codex app on macOS
Support for Windows systems is expected in the future.
Why This Update Matters Beyond Coding
This update is not just about mobile access.
It reflects a bigger shift toward AI systems that can work continuously across devices and workflows.
Instead of opening apps for every task, users may increasingly supervise AI agents running in the background.
In this model, smartphones act more like control panels, while real processing happens across connected systems.
Experts believe this approach could expand beyond coding into areas like:
Research
Design
Customer support
Cybersecurity
For developers, Codex on mobile makes it easier to move quickly from idea to execution without being tied to a desk.
