You have to try a little harder with GPT to get it to understand its mistakes, but it's not as bad as it used to be, at least if you pay. It failed for me the first time ("Earlier inert, it could rouse in fury before long"), but not the second ("In a lull, may soon yawn"). With a little more pushing it got a much better result ("In a lull, may soon arise").
