I take this idea even further: After the LLMs have critiqued each other, I introduce a third critique and review it myself as a human. This third party review is most effective at highlighting problems that the LLMs miss, in my experience.

Jokes aside, I agree about having LLMs iterate. Bouncing between GPT and Opus is good in my experience, but even having the same LLM review its own output in a new session started fresh without context will surface a lot of problems.

This process takes a lot of tokens and a lot of time, which is find because I’m reviewing and editing everything myself during that time.
