Google Drive is now in Library

If you have the Google Drive plugin connected, you can now see and browse your Google Drive files and folders directly from Library, including items shared directly with you. You can also quickly pull up a Drive file from the composer or with @mentions and add it to any chat—without uploading it again.

When you’re working with a file, you can now keep Google Docs, Sheets, and Slides open beside the conversation while asking ChatGPT to summarize, analyze, compare, or create something new from them. You can also select a folder and ask ChatGPT to work across the files it contains. Your content stays connected to Drive, so it’s easy to return to the original. Where supported and authorized, ChatGPT can update the source file directly.

Availability

The initial experience includes My Drive and files and folders shared directly with you; Shared Drives aren’t included yet. Some Google Drive editing and collaboration features aren’t yet available in ChatGPT.

Rolling out to Plus, Pro, Enterprise, Edu, Healthcare and Business users on the web in both the Chat and Work toggles. Mobile support will follow.

Chat model defaults

Workspace owners and admins can configure the starting Chat model and reasoning level from Workspace settings > Models. Owners and admins can apply an admin default or allow User’s last choice for new chats - note that defaults do not grant access to unavailable models or override enforced workspace requirements.

The ChatGPT Desktop app should be upgraded to version 26.812.10818 or later for the new controls to take effect.
