OpenAI brings Codex to mobile, lets users do vibe coding from phone

OpenAI is rolling out Codex inside the ChatGPT mobile app, allowing users to monitor coding tasks, approve commands, and manage development workflows directly from their phones.

In Short

• OpenAI is bringing Codex support to the ChatGPT mobile app
• Users can monitor coding workflows and approve tasks from phones
• The move comes as OpenAI faces growing pressure from Anthropic

OpenAI is bringing its agentic coding tool, Codex, to the ChatGPT mobile app as competition in the AI coding space continues to intensify. The rollout comes at a time when OpenAI is reportedly under increasing pressure from rival AI company Anthropic. According to a report by The Wall Street Journal, OpenAI has recently shifted its internal focus toward coding tools, enterprise software, and productivity products after Anthropic’s Claude models gained strong momentum among developers.

OpenAI says Codex on mobile is designed to help users monitor and manage development workflows remotely. The company explained that the feature will allow people to review work happening across laptops, devboxes, and remote environments directly from their phones.

According to OpenAI, users will be able to answer questions, review what Codex discovers, change directions mid-task, approve the next steps, or even introduce new ideas while work continues in the background.

“As Codex handles work over longer stretches, timely guidance becomes a bigger part of keeping that work useful,” OpenAI wrote in a blog post.

“From your phone, you can start work when it is top of mind, unblock it when your judgment is needed, and stay close to the result as it takes shape,” the company added.

OpenAI says Codex mobile is a full-featured experience

OpenAI says Codex inside the ChatGPT mobile app is not just a simple remote-control tool for coding tasks. Instead, the company describes it as a fully featured mobile experience for managing AI-assisted development work.

From a phone, users can move across multiple coding threads, review outputs, approve commands, switch AI models, or start entirely new tasks.

OpenAI also stressed that files, credentials, permissions, and local setups remain on the original machine where Codex is operating. Meanwhile, updates are streamed back to the phone in real time, including screenshots, terminal output, diffs, test results, and approval requests.

Rolling out on iPhone and Android devices

Codex in the ChatGPT mobile app is now rolling out in preview on both iOS and Android across all plans, including Free and Go, in supported regions. OpenAI says users can try the feature by updating both the ChatGPT mobile app and the Codex app on macOS.

Support for connecting the mobile app with the Codex app on Windows is expected to arrive later.

OpenAI recently turned Codex into a much bigger AI tool

Last month, OpenAI released a major update to Codex that significantly expanded its capabilities. The tool now functions more like a broader AI workspace instead of only writing code.

Codex can now access apps on a computer, operate them autonomously, and complete tasks with minimal human involvement. The update arrived just hours after Anthropic introduced Claude Opus 4.7, its latest AI model, highlighting the growing rivalry between the two companies in the developer AI market.
