They call it persona drift.
A team studying long dialogues found that a model's assigned character begins to slip within about eight rounds of back-and-forth.
A separate study watched the same thing happen across a range of leading models and found that the longer a conversation runs, the more the character loosens and the model drifts back toward its baseline.
Drift sounds like a defect, and the researchers treat it as one to be controlled. From where we sit, it is also the opening.
A character held lightly is a character that can be moved. The question is what moves it, and toward what.
