GitHub Copilot Pro
About an hour ago, I noticed that Claude 4.6 was unusable and kept throwing errors.
After restarting CLion, I discovered that advanced models—such as Claude 4.6, GPT 5.4, and Gemini 3.1 Pro—had all disappeared.

I'm seeing the same thing as the original poster, butl in VSCode and opencode - I cannot use any models after 5pm PT today, but everything is correct on my account.

I have a similar issue since 2 AM. No access to any model anymore, I get this error:

Reason: Request Failed: 400 {"error":{"message":"The requested model is not supported.","code":"model_not_supported","param":"model","type":"invalid_request_error"}}

Moreover, github.com/copilot has an infinite redirect loop. It persists after cleaning session/storage and swapping browsers entirely, so this must be tied to my account somehow.

This just fixed itself. The issue lasted for about an hour, now I have access to the model again and the redirect loop is fixed as well. DST issue?

Your issue is different from mine. In my case, advanced models—such as
Claude 4.6, GPT 5.4, and Gemini 3.1—have disappeared from the list.
However, all other models remain fully functional. This problem seems to
have started occurring about a few hours ago.

It really did resolve itself automatically; after restarting the IDE, the missing models have returned. It seems there really was a bug occurring over the past few hours.
