The author's bit about "IterateGPT" reminds me of this "AI in a loop" post from last year: https://til.simonwillison.net/llms/python-react-pattern

  prompt = """
  You run in a loop of Thought, Action, PAUSE, Observation.
  At the end of the loop you output an Answer
  Use Thought to describe your thoughts about the question you have been asked.
  Use Action to run one of the actions available to you - then  return PAUSE.
  Observation will be the result of running those actions.
  ..."""

Seems like a really powerful technique to have LLMs act on their own feedback.
