Hey @jiacai2050 . It is unclear to me which label I am supposed to use - I do use AI for research and review, but the code ultimately is mine. Similarly, because the label is unclear, I don't think it will do the readers any good if I just pick one, because they can't infer any information about it either.

Besides, there are projects on the list that are mostly AI generated, but do not have AI attribution tag. From a glance, if mine has AI tag in it, and they don't (even though I am sure AI involvement in my project is not even close), it will create an unfair impression that mine has more AI involvement than theirs - this is not what I want for a project that I spent so much time on, instead of just "vibe coding" it.

For those reasons, please reconsider enforce this rule across the board, and clarify the AI attribution tags.

Thank you.
