IMO: they need to add an Ai tagging feature to E621. Ai is basically purpose built for image tagging. Then users could upvote/downvote accurate tags the Ai suggested. If the tag is highly upvoted, then it could be added to the image. Welcome to my Ted talk.

Thanks for listening to my rant

• I belive that is closer to machine learning than AI since you’re just teaching a program to recognize something on a picture by comparing it to similiar thing on other pictures.
• The problem you encounter is making it money efficiant since e621 is mostly non profitable besides selling the name and shilling the parent company while big AI models are REALLY power hungry. Mi****oft restarted whole nuclear power plant to manage energy demand.
• If you propose a smaller model there is a problem of human expercionism. In other words every artist has his own artstyle. So you need the model to recognize EVERY possible artstyle which means you need to train it on EVERY possible artstyle which is not possible right now while making the AI somewhat usable.
• Now let’s set all previous problems aside and say they have the power, knowlage, time, will and money. You now need to actually train the AI. For that you need the training material. “No problem” you say to yourself. You run the biggest furry art archive on the internet. Well, that is the thing it is an archive, not your art. So you would need to ask EVERY artist whose art EVER got uploaded to the archive if they consent for AI to be trained on art they made, which if you can contact every of them I guarantee 95% will say no. And I belive you now need to do the same for people who taged those art pieces to give the AI something to learn from.
• with all that work you are left with mediocre algorithm who is 80% accurate 20% of the time. .
• In conclusion AI is not a silver bullet for every problem, not even something like tagging since they are really not as amazing as big corpos make them to be.

TLDR >!AI is not a solution from moral, practical and economy standpoint!< . Of course I am open to other’s standpoint so correct me if I am wrong anywhere. :3
