An article from OpenAI on how they created a complete project without any human-written code.

This is, of course, kind of marketing material for OpenAI, but it also has interesting points:

 code throughput increased, our bottleneck became human QA capacity.


 management is one of the biggest challenges in making agents effective at large and complex tasks. One of the earliest lessons we learned was simple: give Codex a map, not a 1,000-page instruction manual.


 the agent’s point of view, anything it can’t access in-context while running effectively doesn’t exist. Knowledge that lives in Google Docs, chat threads, or people’s heads are not accessible to the system. Repository-local, versioned artifacts (e.g., code, markdown, schemas, executable plans) are all it can see.


And the most important point, in my opinion:

 kind of architecture you usually postpone until you have hundreds of engineers. With coding agents, it’s an early prerequisite: the constraints are what allows speed without decay or architectural drift.
...
In a human-first workflow, these rules might feel pedantic or constraining. With agents, they become multipliers: once encoded, they apply everywhere at once.


In any case, it's an interesting read. Obviously, it's all related to a completely green field project. So, your mileage for decade-old monoliths may vary.

P.S. Also, according to the diagrams in this article, OpenAI uses VictoriaMetrics, which is also cool :)
