    Sorry you have to deal with this. You can stay on GitHub Copilot. Here is what to change before November 16, 2026:

1. Find where you pick a model. Check Copilot settings, prompt files, agent setups and scripts for these model names.
2. Switch the model. Use Claude Opus 5.5, GPT-6.1 Sol or GPT-6 Luna instead.
3. Admins: check model policies. If you turned off the global default, turn on the new models in Copilot settings.
