OpenAI rolled out Codex access through the ChatGPT mobile app for iOS and Android, enabling developers to remotely control coding sessions running on their computers. The move comes as OpenAI intensifies competition with Anthropic's Claude Code, with over four million developers now using Codex weekly. Users can review outputs, approve commands, and manage workflows from their phones while files stay secure on their desktop machines.
OpenAI Codex Expands to Mobile Platforms
OpenAI has officially launched OpenAI Codex access through the ChatGPT mobile app, marking a significant expansion for its AI coding tool as the company races to compete with Anthropic's increasingly popular Claude Code

The Codex programming assistant now serves more than four million weekly users, and this mobile expansion addresses a critical gap in developer workflows
2
. Previously, developers who launched long-running programming tasks and stepped away from their computers had no way to provide the AI coding assistant with necessary guidance, potentially stalling projects for hours5
.Remote Control of Codex Keeps Projects Moving
The ability to manage coding tasks remotely fundamentally changes how developers can build apps on the go. From the ChatGPT mobile app, users can work across all threads, review outputs, approve commands, change models, or start something new in Codex
1
. Your files, credentials, permissions, and local setup remain on the machine where Codex operates, while updates flow back to your phone in real time, including screenshots, terminal output, diffs, test results, and approvals.

This architecture means developers can keep systems running during commutes or while running errands, intervening when Codex completes a task or needs prompting on next steps
2
. The mobile feature currently works with Codex on macOS systems, though Windows support is already on the roadmap3
.Reducing Inference Costs While Battling Anthropic
OpenAI's strategy centers on making Codex cheaper and easier to use as it battles Anthropic for developers and enterprise business customers
4
. The mobile access reduces inference costs by allowing developers to interrupt Codex if it starts implementing a software module in a non-optimal manner, avoiding unnecessary token usage that would otherwise inflate ChatGPT bills5
.The announcement came one day after CEO Sam Altman announced that companies switching to Codex will receive two months of free usage, following reports of Anthropic raising prices
4
. This pattern has become familiar between the rivals: Anthropic lifts prices due to surging demand, while OpenAI lowers them hoping to capture market share. Anthropic's Claude Code already offers mobile access through remote control sessions, making OpenAI's move essential to remain competitive.Related Stories
New Customization Features for Enterprise Workflows
Alongside mobile support, OpenAI introduced two additional capabilities called Hooks and Remote SSH
5
. Hooks enables customers to customize the AI coding assistant with scripts—cybersecurity professionals could write scripts blocking developer prompts containing sensitive company information, while legal teams might use Hooks to log Codex messages for regulatory compliance. Scripts can process both prompts and responses, allowing teams to customize Codex output for each project.Remote SSH enables Codex on mobile devices to connect to cloud-based development environments via encrypted network links, addressing situations where software teams write, test, and store code remotely rather than on local machines
5
. Additional updates include support for HIPAA compliance in local environments for ChatGPT, allowing hospitals and healthcare organizations to adopt the tools more broadly4
.Strategic Implications for Developer Adoption
OpenAI's push reflects its broader ambitions to create a desktop superapp, with recent major updates enabling Codex to operate apps on macOS

. The company has been cutting back on "side quests," shutting down projects like the Sora video-generation tool to focus on growing its enterprise business and catching up to Anthropic's momentum.

However, approving agents on small screens could introduce greater risk for errors when users multitask
4
. Additionally, increasing Codex usage means consumers will use more compute, the most precious resource for AI labs. OpenAI's strategy has relied on compute subsidies to drive adoption, raising questions about long-term sustainability as developer workflows become increasingly mobile-first.References
