OpenAI brings Codex to phones

OpenAI on May 14 put Codex into the ChatGPT mobile app in preview, extending its coding assistant to iPhone and Android users who want to manage active software work away from a desk. The company said the mobile experience lets users start or continue threads, answer questions, change direction, approve actions and review what Codex has found while the underlying work keeps running on a connected machine. OpenAI said the release is available in all supported regions through the ChatGPT mobile app. The company described the feature as a way to stay connected to active work across laptops, devboxes and remote environments. ### What exactly can people do from a phone? Codex in the ChatGPT mobile app can load the live state from a connected environment, OpenAI said, allowing users to move across active threads, approvals, plugins and project context from a phone. The company said users can monitor work in real time, steer tasks, approve next steps and spin up new work without returning to their desks. The May 14 product post said Codex continues running on the connected host rather than directly on the phone. (openai.com) OpenAI’s help documentation says users can currently connect a phone to Codex running on macOS, while a community post announcing the preview said support for connecting a phone to the Codex app on Windows is coming soon. ### Does this mean coding now happens on the device itself? OpenAI’s own description points to remote control and review rather than fully local code execution on the handset. The company said the app keeps users “in the loop” while Codex works across laptops, Mac minis or managed remote environments, and said the phone experience is designed to monitor, steer and approve coding tasks across devices. (help.openai.com) The current setup matters because OpenAI’s release notes describe mobile Codex as a companion surface for ongoing work. The notes say users can keep an investigation moving, make a decision when Codex reaches a fork and move across connected hosts, but they do not describe the phone as the primary execution environment.

A separate OpenAI post about earlier Codex upgrades also said the product experience is connected by a user’s ChatGPT account across local and cloud environments. ChatGPT Business documentation emphasizes usage controls around Codex. OpenAI’s help center says workspace owners can add credits, enable auto-top-up, review usage analytics and set spend controls for Codex in ChatGPT Business. (help.openai.com) Another billing article says self-serve ChatGPT Business billing covers standard ChatGPT seats and usage-based Codex seats. (openai.com) ### How is OpenAI charging for Codex usage? OpenAI’s Codex rate card says the company changed pricing on April 2, 2026, to align with API token usage instead of per-message pricing for new and existing Plus, Pro and ChatGPT Business plans, and for new ChatGPT Enterprise plans. The help article says that update was extended on April 23, 2026, to all existing ChatGPT Enterprise plans, including Edu, Health, Gov and ChatGPT for Teachers. (help.openai.com) Those billing details line up with OpenAI’s push to surface credits and limits inside ChatGPT Business. The help center says administrators can use workspace-level limits and analytics when their workspace has Codex seats or expects additional Codex usage from standard ChatGPT seats. ### What comes next in the mobile rollout? OpenAI said on May 14 that the mobile preview was rolling out that day on iOS and Android in supported regions. (help.openai.com) The same announcement said Windows support for connecting a phone to the Codex app is the next named step in the rollout, though OpenAI did not give a date. The company’s release notes and product pages remain the main reference points for availability, supported hosts and billing details. (help.openai.com) As of May 15, those pages describe mobile Codex as a preview feature inside the ChatGPT app and point business users to credits, analytics and spend-control settings in ChatGPT Business.
