Question

I'm using GitHub Copilot Business with all models enabled by admin.

I've successfully configured the connection via opencode auth login and can use models like sonnet 4.5, gpt 5.2, and gemini 3 flash without issues.

However, when using gemini3pro, I get the following error:

The requested model is not supported.
Make sure the model is enabled in your copilot settings: https://github.com/settings/copilot/features

Is there something I'm missing or doing incorrectly?

This issue might be a duplicate of existing issues. Please check:

  • #8598: Copilot requested model not supported - Similar error where models enabled in GitHub Copilot settings show as unsupported in OpenCode
  • #8417: Gemini Bad Request with Github Copilot - Related issue with Gemini models failing when using GitHub Copilot authentication

Feel free to ignore if none of these address your specific case.

And it is enabled to confirm?

Any chance it wasnt, no is, and you are still getting issue (cause it could be stale cache)

It's confirmed. It shouldn't be a stale cache issue because I literally just installed opencode and set up Copilot auth 30 minutes ago on this machine.
Also, referring to issue #8598, it looks like gemini3pro still has this problem.
It seems I'm not an isolated case.

Same issue here. As a side note, copilot with gemini 3 pro through VS Code works normally.

I had the same issue. What worked for me was reinstalling OpenCode, and then it worked fine.

I had to reauthenticate. But not just do /connect and connect again. But completely do a logout in opencode and then log back in and these models started working again.

Was experiencing this earlier but it was fixed when #8598 was closed.

However, it is happening again with GPT-5.2-Codex. Running OpenCode 1.1.25

Hi @MrZander, can you try logging out of the GitHub Copilot plugin and logging back in? I think you have the older auth token cached and that's causing issues.

May I ask how you operated it? I deleted the auth.json file, logged in again, and used Claude-related models, but I still get this error.

@wenbochang888 i didn't delete anything by hand. I just used the regular logout process inside opencode. Then I tested codex. I didn't test any anthropic model. So my observation is only about codex and gemini 3 pro.

Make sure that you did log out and in again to re-authorise. I did that and everything was working correctly ever since.

Also make sure that you have enabled models in github copilot settings and that you haven't exceeded your tokens usage for the month.

No idea, TBH. It works here. I wish I could help you more. But I'm afraid you'll have to figure it out on your own. Maybe there's something wrong with your subscription to copilot or something. Check if it works in vscode. And probably we shouldn't really talk about it here in issues as this is not "support". You might want to join opencode community and ask there: https://discord.gg/opencode
