I think the key takeaway here is how trivially easy it is to provide GPT with an API that it can use. Having it recursively call itself like in this example is interesting but you could also have it act as a coordinator of multiple GPT models, the markup language with specified roles would make it easier to keep track of the flow of information coming back. If I wasn't already working on another project using GPT I'd start exploring this.
