I keep hearing the assertion that you can’t make high quality, maintainable code with LLMs. The last two years using AI have shown me exactly the opposite.
I think it’s all about the structure you use to work in and how you use the model. We are shipping better, more human friendly code, with less bugs, then we ever did before and doing it at 1/10 the cost before LLMs.
But we are definitely not vibe coding, and the key seems to be devs with years of experience managing teams, managing the LLM instead. Basically you create the same kind of formal specifications, conventions, and documentation that you would develop for a project with two or three teams, then use that to keep the project on the rails recursively looping back through the docs as you go along. I’ve only had to back out of a couple of issues over the last year, and even though that cost a couple of hours, it was still extremely cheap.
Meanwhile we are shipping at 4x speed with 1/4 the labor, and the code is better than it was because the “overhead” of writing maintainable, self documented code has inverted into the secret ingredient to shipping bug free code at unprecedented speed.
If you just explain the standards to which you want the code written, use a strict style guide, have a separate process that ensures test coverage (not in the same context) you can get example quality code all the way through. Turns out that’s also in the training data.
