We're currently on GPT-4.... You should look up what happened to GPT-1 through 3. If I remember right GPT-2 in particular was ruined by a bad feedback loop that ended up locking it into only writing the most disgusting, vile smut you could think of in response to any query. Not sure what happened to the others but frankly speaking I don't think "feral rampancy" is off the table here.
