OpenAI: Codex Expands To Mobile App, Bringing AI Coding Workflows To Phones

By Amit Chowdhry • Yesterday at 10:47 PM

OpenAI announced that ChatGPT users can now access Codex directly from their phones through a new preview rollout in the ChatGPT mobile app, allowing developers and teams to monitor, guide, and collaborate with AI-powered coding workflows from anywhere.

The company said Codex can now stay connected to development environments running across laptops, devboxes, Mac minis, and remote infrastructure while syncing live activity to mobile devices in real time. According to OpenAI, more than 4 million people are already using Codex every week, and the new mobile experience is designed to help users manage long-running AI tasks without needing to remain at their desks.

The mobile integration enables users to review outputs, approve commands, switch models, manage active threads, and launch new tasks directly from their phones. OpenAI emphasized that files, permissions, credentials, and local configurations remain on the original machine running Codex, while screenshots, diffs, terminal output, test results, and approvals are streamed securely back to the mobile app.

The company said Codex uses a secure relay infrastructure to keep trusted machines reachable across devices without exposing them directly to the public internet. That relay layer also synchronizes active session context across authorized ChatGPT devices.

OpenAI outlined several real-world use cases for the mobile experience, including debugging software issues while away from a desk, reviewing architectural tradeoffs during commutes, preparing for customer support calls using AI-generated summaries, and capturing new project ideas while on the go.

The company also announced that Remote SSH support is now generally available, enabling Codex to connect directly to managed enterprise environments and remote developer infrastructure. OpenAI said the desktop app can automatically detect SSH hosts from configuration files, allowing users to run projects and threads on remote machines similarly to local environments.

Additional enterprise-focused updates released alongside the mobile rollout include:

  1. Programmatic access tokens for CI pipelines, release workflows, and internal automation tools.
  2. General availability of Hooks, which can scan prompts for secrets, run validators, log conversations, create memories, and customize Codex behavior across repositories and directories.
  3. HIPAA-compliant Codex support in local environments for eligible ChatGPT Enterprise healthcare deployments.

OpenAI said Codex in the ChatGPT mobile app is rolling out in preview on iOS and Android across all subscription tiers, including Free and Go plans, in supported regions worldwide. Support for connecting the mobile app to the Codex Windows app is expected soon.
