San Francisco: OpenAI has rolled out its AI-powered coding tool Codex to the ChatGPT mobile app, allowing users to manage development workflows directly from their smartphones. The move marks a significant step in the growing competition within the AI coding space, particularly against rivals like Anthropic.
The new feature enables developers and users to monitor, guide and control coding tasks remotely, turning smartphones into active hubs for AI-assisted software development.
Codex brings coding workflows to smartphones
OpenAI said Codex on mobile is designed to help users stay connected to their coding tasks even when they are away from their primary systems.
With the integration, users can:
- Review ongoing coding tasks across devices
- Approve or modify commands
- Answer queries raised by the AI
- Redirect tasks or introduce new instructions mid-process
The company highlighted that as AI tools handle longer and more complex workflows, real-time human input becomes increasingly important.
“From your phone, you can start work when it is top of mind, unblock it when your judgement is needed, and stay close to the result as it takes shape,” OpenAI noted.
Not just remote control, but a full-featured experience
OpenAI emphasised that Codex on mobile is more than just a companion tool. Instead, it offers a complete development management experience.
Users can:
- Navigate multiple coding threads
- Review outputs and logs
- Switch between AI models
- Launch new development tasks
The system streams updates such as terminal outputs, screenshots, code changes (diffs), and test results directly to the phone in real time.
Importantly, OpenAI clarified that sensitive data like files, credentials and permissions remain on the original machine, ensuring security while enabling remote access.
Rollout across iOS and Android
The Codex mobile feature is currently rolling out in preview across both iOS and Android platforms via the ChatGPT app.
It is available across multiple subscription tiers, including Free and Go plans, in supported regions. To use the feature, users need to update both:
- The ChatGPT mobile app
- The Codex application on macOS
Support for Windows systems is expected to be introduced later.
AI coding race heats up
The launch comes at a time when competition in the AI developer tools space is intensifying. Reports suggest OpenAI has recently shifted focus towards coding tools, enterprise solutions and productivity software.
This shift follows growing traction for Anthropic’s Claude models among developers. The rivalry between the two companies has accelerated innovation, with both releasing major updates in quick succession.
Recently, OpenAI expanded Codex into a broader AI workspace capable of interacting with applications, automating tasks and performing complex workflows with minimal human intervention. The update arrived shortly after Anthropic introduced a new advanced AI model, underlining the fast-paced competition.
What this means for developers
The addition of Codex to mobile devices reflects a broader trend of making AI tools more accessible and continuous. Developers are no longer restricted to desktops or laptops and can now intervene in workflows anytime.
This could significantly improve productivity, especially for:
- Remote teams
- Freelance developers
- Startups managing distributed systems
At the same time, it raises questions about the increasing reliance on AI systems for critical development tasks and the need for careful human oversight.
Conclusion
OpenAI’s move to bring Codex to mobile signals a major shift in how software development workflows are managed. By enabling real-time interaction with AI coding systems from a smartphone, the company is pushing towards a future where development is continuous, collaborative and device-agnostic.
As competition with rivals like Anthropic intensifies, innovations like these are likely to reshape how developers build, test and deploy software in the coming years.
