It seems like it tends to converge into infinite loops at some point. Example by directly inputting a repeated "What?", originally obtained with a different piece of initial text, and observed with other starts as well :) :

Prompt:

"What?"

"What?"

"What?"

"What?"

"What?"

"What?"

"What?"

Response:

Same

I suppose it's kind of GPT's game of life :)
