This shit is killing the internet.
I've found adding -AI to image search results still kills a lot of garbage. It doesn't filter everything and not every search engine has it, but it helps.
Really cool how we made a tool for sharing information and then said we should also clog it up with a bunch of fabricated bullshit to the point of making it damn near useless
There's probably a TamperMonkey script that someone has written.
https://github.com/ZenithO-o/Fix-Google-Web-Search is one I found but haven't tested
The problem I've found using udm=14 is it removes everything but traditional search results. No calculator, no weather widget, no map results, etc.
Unfortunately there's not really any logical way to automatically filter AI generated images that aren't tagged as such.
The best you could do is have another AI to detect AI generated images.
