"The requested model is not supported." while using gemini3pro in Github Copilot

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:

• Copilot requested model not supported #8598: Copilot requested model not supported - Similar error where models enabled in GitHub Copilot settings show as unsupported in OpenCode
• Gemini Bad Request with Github Copilot #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, and Gemini 3 Pro is enable since it came out on Github Copilot.

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

Same here with version 1.1.23, NPM install and running linux.
Gemini 3 pro works just fine with copilot-cli

Same issue.

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.

Same issue. I've already tried logging out and reinstalling, but it still doesn't work.
