I was answering in messages i really don't know if i can do that .
And about that post when i saw this post it had a ai-generated tag like other post in pixiv i don't know how this tags works and if the artist works are ai-assisted and and pixiv detect the use a ai-generated program and generates the tag but the autor can eliminate after or not im try to be careful about Danbooru and AIBooru that image really had the ai-generated tag what happen after i really don't know i actually updated a pair of his post in Danbooru when i saw that post with the tag thats surprised me but that was the reason i uploaded here
From what I understand, having posted a few things there so far; when you upload something to Pixiv, you have to check a box saying whether the upload is an AI-generated work or not. If yes, then Pixiv applies a tag of it's own to distinguish it once it's posted (example: pixiv #109141856) and at that point the only way to remove it would be for the uploader themselves to edit the upload and change their selection to mark it as not AI-generated then re-submit it.
Of course the system only works to some degree because people still mark AI uploads as not being AI and it seems to mainly rely on the uploader being honest. I also don't think Pixiv does anything about it unless you report it (and even then maybe they wouldn't anyway), but I wouldn't know since I never bothered with that.
There are other tags that can be added that are related to identify AI works (like AI-generated illustration, but depending on the settings the uploader chose, tags on an upload can be added and removed by other users or locked so no can can add/remove anything.
To my knowledge, there isn't anything about Pixiv that can auto-detect if an artwork is AI-generated and automatically apply tags to it. It's on the uploader to tag their stuff properly and obviously people there lie and try to pass of AI works as non-AI stuff and then it leads to the issue of works having a potential issue (either due to a simple mistake or some intentional artistic choice) being mistaken as AI-generated.
