I noticed throughout some of my threads, the model kept switching silently. If I used "try again" selecting a different model, it would still revert to 5.1. Then I noticed the information bubble…
I realise this isn't a new feature, but it would never route my conversations prior to 5.1 release.
How the hell do you stop this? The only workaround I've found so far is asking chat to respond again, then it will pump out a response in the model I originally selected.
