OpenAI has enhanced its software engineering agent, Codex, with new capabilities aimed at making it more versatile and accessible. The update, announced at OpenAI's Dev Day, includes persistent and reusable cloud development environments that can be accessed from any device, moving beyond isolated remote sandboxes.
These new environments are designed to speed up task initiation and provide teams with a shared workspace featuring approved settings and permissions. Developers can now run Codex on their computers, remotely from their phones, or directly in the cloud.
Further enhancements include an updated Codex CLI that allows developers to start and direct tasks using voice commands. A new '/agents' view is intended to simplify delegating work and tracking multiple tasks concurrently. Improvements have also been made to everyday tasks like editing prompts, resuming sessions, and using worktrees, alongside a redesigned terminal user interface for better readability during long sessions.
