What do you consider "serious", as that seems to be the main differentiator here. I know plenty of serious (multiple years of development and users, and began prior to LLMs) projects that have devs using LLMs for development.

That makes me curious, would you like to list them?

		They aren't anything particularly special, most projects I interact with have at least 1 dev who uses LLMs in some capacity. The two I was thinking of when I posted are the Minecraft modpack GregTech: New Horizons, and an Old School Runescape plugin. https://github.com/gtnewhorizons https://github.com/osrs-reldo/tasks-tracker-plugin
