> I can't find a single open source codebase, actively used in production, and primarily maintained and developed with AI

This popular repo (35.6k stars) documents the fraction of code written by LLM for each release since about a year ago. The vast majority of releases since version 0.47 (now at 0.85) had the majority of their code written by LLM (average code written by aider per release since then is about 65%.)

I think we need to move the goalposts to "unrelated to/not in service of AI tooling" to escape easy mode. Replace some core unix command-line tool with something entirely vibecoded. Nightmare level: do a Linux graphics or networking driver (in either Rust or C).

		Yes, I agree. The same way that when you ask "Are there any production codebases written in Language X", you typically mean "excluding the Language X compiler & tooling itself." Because of course everyone writing a tool loves bootstrapping and dogfooding, but it doesn't tell you anything about production-readiness or usefulness / fitness-for-purpose.
