ChatGPT for Word

ChatGPT is now available in Microsoft Word. You can draft from notes, summarize a document, revise selected text, and adjust headings and formatting from the ChatGPT sidebar. Word joins Excel and PowerPoint through the same Microsoft add-in.

ChatGPT for Word is available on all ChatGPT plans, including Free. Your plan’s token limits apply, and Word draws from the shared usage allowance for Codex and other premium features on plans that include it.

For ChatGPT Business, Enterprise, and Edu, workspace admins can turn Word access on or off in the ChatGPT admin console. Microsoft 365 admins must also allow the ChatGPT add-in. Starting Oct 1, 2026, Word access will be enabled by default.

For ChatGPT Business, Enterprise, and Edu, Word uses token-based pricing at the API rates for the model you use.

Bring your personal and work accounts into the same conversation, so ChatGPT can help you find information and get things done across your personal and work accounts.

Manage API Platform access with SCIM

Tenant-wide SCIM now supports API Platform. Enterprise and Edu global admins can assign synchronized groups to API organizations and selected projects through Product access in Admin Console. This extends the existing tenant-wide SCIM setup for ChatGPT workspaces and Ads accounts.

Members receive access without accepting an invitation. Manage synchronized group membership in your identity provider, and SCIM updates the API memberships it manages as group assignments change.

Updated permissions for new Health connections

For new Health plugin connections, ChatGPT will now default to each user’s global plugins permissions setting.

If you make no changes to your Plugins settings, the default permission setting is “Allow low-risk actions.” This means that once you’ve connected your information in Health, ChatGPT can use it when relevant without asking for permission each time, unless you are attempting a sensitive action, such as asking ChatGPT to email a training plan based on your data to a running partner.

This change reflects what we’ve seen from users: more than 70% of Health users already choose to allow ChatGPT to use data connected in Health without asking for permission each time.

You can change your Health permissions anytime in Settings → Plugins → Health.

Retiring automatic switching to Thinking in ChatGPT

We’re retiring automatic switching from Instant to Thinking (reasoning) for ChatGPT Plus and Pro users globally. You can still select an available option in the model picker to give ChatGPT more time to think or reason.

We’re also removing the Higher intelligence setting from ChatGPT on the web for these plans. ChatGPT can still switch automatically for safety purposes.
