OpenAI's Codex can now operate your Windows PC autonomously, hunting bugs and testing apps on its own

OpenAI expanded Codex’s Computer Use to Windows 11, letting the AI interact with apps and files on a PC.

Users can now start or monitor autonomous tasks remotely through the ChatGPT app on iPhone and Android.

The update pushes Codex beyond a developer tool toward unattended Windows automation and mobile control.

OpenAI says this fits its broader goal of building a general-purpose app for work and daily life.
