OpenAI has brought its Codex coding agent to the ChatGPT mobile app, providing iPhone and Android users with remote access to Codex sessions running on a Mac.

OpenAI said on Thursday its coding tool ​Codex was being added to ‌the ChatGPT mobile app, ​expanding access to the ⁠product as competition intensifies in the market for AI code-generation tools.

The mobile version of Codex comes with a secure relay layer, which allows trusted machines to be accessible across devices without exposing them directly to the public internet.
