Funny you mention that because the OMP GitHub issues (https://github.com/can1357/oh-my-pi/issues) is almost exclusively attended to by a very efficient bot. I routinely submit issues and they’re replicated and resolved (via PRs) in ~30 mins.
To your question: it’s the difference between one person and an agent working on something vs an experienced dev and the entire community.
Time and tokens too of course.
Oh-my-pi seems to like robo coding, while pi itself is entirely against vibe coding for production. (The clanker is a tool, not a free wheeling agent.)
And I see that tonight pi has had their regular devs ship (https://github.com/earendil-works/pi/tags) new releases with modified thinking levels for GPT-5.6 while roboomp is discussing this back and forth with some contributors in oh-my-pi's repo.
