Hey, that’s not a bug. Quick Edit Cmd-K uses Auto routing. The model in your screenshot just used the family name instead of the exact slug. That’s common for LLMs, they don’t always know their exact version.
The model picker in Cmd-K was removed on purpose a few releases ago, see Can’t select model in Quick Edit Can't select model in Quick Edit. If you need model control, use Agent Cmd+L, model selection is available there.
I tested it many, many times. The Cmd-K model says it’s GPT 4 or GPT 4 Turbo 100% percent of the time, while the Cmd-L Auto router+model always says it’s Auto. So there must be a difference, though maybe it’s just because of some outdated part of the system prompt you guys forgot to change.
Does Auto routing include GPT 4 as one of the possible models? Are you sure that Cmd-K uses the exact same Auto routing as Cmd-L?
