The Codex app has been released, offering a new way to interact with the Codex AI model. The app allows users to run and supervise multiple agents across projects and execute longer-running tasks in parallel. The discussion around the app reveals that it is seen as a more polished and user-friendly interface for Codex, but some users prefer the existing VS Code extension or other tools like Claude Code. The app's limitations, such as the lack of remote development capabilities, are also discussed.
