Now, there was a paper that instantiated a couple dozen LLMs and had them run a virtual software dev company together which got pretty good results
Dude, you need to take a closer look at that paper you linked, if you consider that “pretty good results”. They have a github repo with screenshots of some of the “products”, which should give you some idea github.com/OpenBMB/ChatDev/tree/main/misc .
Not to mention the terrible decision making of the fake company (desktop app you have to download? no web/mobile version? for a virtual board game?)
(Also the paper never even tried to prove its main hypothesis, that all this multi agent song and dance would somehow reduce hallucinations and improve performance. There is a lot of good AI stuff coming out daily, but that particular paper - and the articles reporting on it - was pure garbage.)
