Copilot Model Picker Missing in Microsoft 365 Chat: Fix

You open Microsoft 365 Chat in Teams or the web app and the dropdown that lets you switch between Copilot models — like GPT-4, GPT-4 Turbo, or a custom model — is gone. This is not a UI refresh. The model picker disappears when your tenant or user license does not match the requirements for multi-model support. This article explains why the model picker vanishes and provides the exact steps to restore it.

The model picker is controlled by two factors: the Copilot for Microsoft 365 license and the service plan configuration in the Microsoft 365 admin center. If either is misconfigured, the picker is hidden by default. You will learn how to verify your license, check the service plan, and re-enable the model picker through admin settings and user-side cache clearing.

This fix applies to all Microsoft 365 Chat clients including Teams desktop, Teams web, and the Microsoft 365 web app. The steps require global admin or at least billing admin access in the Microsoft 365 admin center.

Why the Copilot Model Picker Disappears

The model picker is a UI element that appears only when the Microsoft 365 Copilot service detects that the signed-in user has a license with multi-model capabilities. The root cause is almost always one of these three conditions:

License Type Restriction

Microsoft 365 Copilot Chat (free chat with limited Copilot) does not include the model picker. Only the paid Copilot for Microsoft 365 license — the $30 per user per month add-on — supports model selection. If a user has only the free chat license, the picker is hidden by design.

Service Plan Disabled

Even with the correct license, the service plan named “Microsoft 365 Copilot Chat” must be enabled in the admin center. This service plan controls the backend model routing. If an admin has disabled this plan to restrict model variety, the picker disappears.

Stale Client Cache

After a license or service plan change, the Microsoft 365 Chat client may still show the old UI state. The browser or Teams desktop app caches the initial configuration. Until the cache is cleared, the picker remains hidden even though the server-side configuration is correct.

Steps to Re-enable the Copilot Model Picker

Follow these steps in order. After each step, test Microsoft 365 Chat by opening a new chat and looking for the model dropdown near the compose box.

1. Verify the user has Copilot for Microsoft 365 license assigned
   Open the Microsoft 365 admin center at admin.microsoft.com. Go to Billing > Licenses. Select the user experiencing the missing picker. Under Product licenses, confirm that Copilot for Microsoft 365 appears and is toggled On. If the license is missing, assign it from Users > Active users by selecting the user, choosing Licenses and apps, and checking the box for Copilot for Microsoft 365.
2. Enable the Microsoft 365 Copilot Chat service plan
   Still in the Microsoft 365 admin center, go to Users > Active users. Select the affected user. Click the Licenses and apps tab. Expand Copilot for Microsoft 365. In the list of service plans, find Microsoft 365 Copilot Chat. Ensure the toggle is set to On. If it is Off, turn it On and click Save changes. Wait 15 minutes for the change to propagate.
3. Clear browser cache and cookies for Microsoft 365
   In your browser Chrome, Edge, or Firefox, press Ctrl + Shift + Del. In the dialog, set the time range to All time. Check Cached images and files and Cookies and other site data. Make sure to include the domain microsoft.com and all subdomains. Click Clear data. Then close all browser tabs and reopen the browser.
4. Clear Teams desktop app cache
   If you use the Teams desktop app, the cache is stored locally. Close Teams completely. Press Windows key + R, type %appdata%\Microsoft\Teams, and press Enter. Delete the contents of the Cache, Code Cache, GPUCache, and Service Worker folders. Do not delete the folders themselves. Restart Teams and sign in again.
5. Force a full UI refresh in Microsoft 365 Chat
   Open Microsoft 365 Chat in your browser or Teams. Press Ctrl + F5 to force a hard reload. This bypasses the local cache and downloads the latest UI configuration from the server. The model picker should now appear as a dropdown labeled Model above the chat input field.

If the Model Picker Still Does Not Appear

If you completed all steps and the picker remains missing, check these additional factors.

The Tenant Does Not Have Multi-Model Support Enabled

Some tenants, especially those on older Enterprise agreements, may not have the multi-model feature enabled at the tenant level. Contact Microsoft support and request that the Copilot Multi-Model Preview be enabled for your tenant. Provide your tenant ID and a screenshot of the missing picker.

Copilot Chat Shows a Different UI Layout

Microsoft periodically tests UI variations. If the model picker is missing but you see a small gear icon or a settings link near the compose box, click it. In some layouts, the model selection is moved to a settings panel instead of a dropdown. Look for a Model or AI model option inside the settings pane.

Copilot for Microsoft 365 License Was Removed and Reassigned

If you removed and reassigned the license, the service plan may reset to Off. Repeat Step 2 and ensure the service plan is enabled again. Then clear the cache again using Steps 3 and 4.

Copilot for Microsoft 365 License Types: Model Picker Availability

Item	Copilot for Microsoft 365 Paid	Microsoft 365 Copilot Chat Free
Model picker available	Yes, when service plan enabled	No, always hidden
Multi-model support	GPT-4, GPT-4 Turbo, custom models	Single default model only
Admin configurable	Yes, via service plan toggle	No admin settings
Requires license assignment	$30/user/month add-on	Included with Microsoft 365 subscription
Cache clearing needed after changes	Yes	Not applicable

The model picker is a direct indicator of your license tier. If the picker is missing, the most common cause is an unassigned or misconfigured Copilot for Microsoft 365 license. After you enable the service plan and clear the cache, the picker should return within minutes. For persistent issues, verify tenant-level multi-model support with Microsoft support.
