I would say AI has generated about 98% of my code for my chat app in the last 3 months and it was definitely not vibe coding. Every function and feature was discussed in detail and some conversations took over a week.
My reasoning for building my chat app wasn't to support vibe coding, but rather to 10x senior developers. Once you know how things work, the biggest bottleneck to a senior developers productivity is typing and documentation. The speed at which LLMs can produce code and documentation cannot be matched by humans.
The only downside is, LLM don't necessary produce pretty or more readable code. The more readable code is something I would like to tackle in the future, as I believe post-processing tools can make LLM code much more readable.
