OpenAI gives Codex reusable cloud environments that work across devices

OpenAI has updated its software engineering agent, Codex, to include persistent, reusable cloud development environments accessible from any device. The update also introduces voice-controlled CLI tasks, improved code review features, and new security infrastructure tools.
Why it matters
These enhancements aim to make AI-assisted coding more flexible and secure for professional development teams, further integrating AI into the software engineering lifecycle.
OpenAI introduced new capabilities for its software engineering agent Codex, making it more useful beyond a developer’s laptop with reusable cloud development environments that can be accessed from any device.
The update, announced at OpenAI’s Dev Day on Tuesday, is one of several for Codex. OpenAI also announced a refreshed Codex CLI, a new code review experience, tools to harden infrastructure, and other API enhancements.
While Codex could already spin up cloud tasks to do work remotely, today’s announcement shows that OpenAI is making those cloud environments more persistent and configurable, rather than treating each cloud task as an isolated remote sandbox.
