Today, we are excited to launch the Windows Computer Use inside the Codex app! Now Codex can see, click, and type in Windows applications to help complete tasks on your PC. Use it for tasks like testing Windows builds, manipulating legacy apps that are not on web, or have it just draw a picture in MSPaint! When Codex is driving your PC, you’ll be able to see every action it takes. You can stop it anytime by pressing ESC. Codex will ask before using apps, and you can set permissions to always allow certain apps. To try it, install the Computer Use plugin from the Plugins marketplace. You can use @Computer, or Codex will use it when it’s the right tool for the job. It's an especialy magical experience when you pair this with Windows remote control that we just launched today too! We hope you like it. Let us know what you think.

Codex can now use the in-app browser to test your app at different viewport sizes! It will control the device tool bar and click through your app at different breakpoints to validate & iterate. If it's a long run, Codex will take screenshots at key moments during testing and show them to you at the end of the turn, so you can verify its work. To speed up testing, Codex can hide the IAB to disable animations, and accelerate testing by 1-2x. Separately, we also made annotations send faster and consume less tokens. Hope you enjoy the updates and let us know what you think!

Today, we are excited to introduce Codex for Chrome! Now, Codex can drive its own Chrome tabs in the background to automate tasks while you use the browser simultaneously. It does this by opening up tab groups for each task, cleaning up at the end, and handing back tabs for review only as needed. Try it for deep research inside logged-in websites, large scale data transfer into any systems of record like CRMs/CMSs, and automating repetitive workflows inside admin consoles & internal tools. Codex will still prefer dedicated plugins if you have them installed, but the Chrome plugin is the universal connector that glues end to end workflows where programmatic coverage is often incomplete. We are making this available on both Windows and Mac today! Let us know what you think.
