Codex App August 25, 2026 Changelog

This update is all about giving ChatGPT more ways to see and interact with the web. It matters most if you use the desktop app or browser extensions and want the AI to help you navigate or log into websites.

What's new

• More browser options: The ChatGPT browser extension isn't just for Chrome anymore. You can now use it in Microsoft Edge, Brave, Opera, and Vivaldi. You can set this up in the desktop app under Settings > Computer Use. All five browsers let the AI see your tabs and control the browser, though Opera doesn't support chatting in a side panel.
• Website tools (WebMCP): When using the desktop app's built-in browser, websites can now offer special tools that let ChatGPT Work and Codex interact directly with the page. You'll need to be using specific AI models (GPT-5.6 Sol or GPT-5.6 Terra) for this to work.
• Cloud browser sign-in: If you're on an eligible plan, you can now ask ChatGPT (on web, iOS, or Android) to log into a supported website for you using a "cloud browser." You'll enter your username and password into a secure sign-in screen, rather than just typing it into the chat. This keeps your cloud browsing totally separate from your personal browser.

Improvements

• The AI can now work more closely with websites. Instead of just reading text on a page, it can use tools provided by the website itself to get things done faster and more accurately.

Fixes

• No specific bugs were mentioned as fixed in this update.
