The requested model is not supported.

Description

The error says Copilot doesn't support this model, but in reality only the Claude model cannot be used properly, while others like Gemini can still be successfully called. I can also use Claude normally within my Copilot. Why is this happening?

The problem still exists.

I solved this problem using brew install anomalyco/tap/opencode on Mac, but what should I do on Windows?

Trying to use GPT-5.2-Codex via GitHub Copilot Enterprise and I'm getting this, and it's enabled on the account

Now of course 5.3 is out, same issue

The opus-4.6 model can be accessed normally in copilot, but when logging into the copilot account in OpenCode and using the Claude-related model, this error message appears.

Same, any update @rekram1-node ?

Currently, I encounter the same issue when using GitHub Copilot's GPT-5.3 Codex, but it works properly when using Cliproxy as a reverse proxy for github-copilot/gpt-5.3-codex.
