Spin off project based on reflection, apparently GPT-4 gets 20% improvement in coding tasks: https://github.com/GammaTauAI/reflexion-human-eval

People finetuning Llama using this prompt structure with much better results: https://twitter.com/Orwelian84/status/1639859947948363777?s=20

Someone already build an autonomous agent using feedback loops (not necessary related to reflexion): https://twitter.com/yoheinakajima/status/1640934493489070080

Seems to yield performance improvement up to a certain point obviously, but it's also a very basic prompt stucture overall one can image all kinds of "cognitive structures"
