That's GitHub Copilot, not "microsoft copilot", the bot built into the Microsoft 365 landing site. it doesn't give you model options, for example.

Same prompt: ffmpeg command to convert movie.mov into a reasonably sized mp4
Yeah it’s really annoying how opaque they are about the model there. Always just ”GPT 4 based” or ”GPT 4o based” if you dig in their blog archives. Makes one unable to check it against benchmarks or see when it’s updated. Setting expectations. Is it a distill? Lower precision quant? An old revision? Who knows.
Whoever decided to use the same brand for different experiences should be demoted at minimum. What a way to destroy trust.
