IVE’s Yujin Sparks Buzz Over AI-Generated Fan Letters at Fansign

IVE’s Yujin is facing controversy over her strong stance against AI-written fan letters.

The controversy began when a fan asked Yujin which scenario would upset her most. She picked finding out her fan letters were written using ChatGPT as her biggest issue.

In a viral clip, Yujin explained why she dislikes it.

Fan: “But isn’t number 1 totally possible?”
YJ: “Really?”
Fan: “But these days people use ChatGPT a lot, like for assignments and stuff.”
YJ: “That makes sense, sure. But now, if it’s a letter to me…”
Fan: “Some people aren’t good at expressing themselves, so they use GPT to make it more detailed and write it better.”
YJ: “Even so, if you’re going to use ChatGPT, fine — but tell me beforehand. If I receive a letter and it smells like ChatGPT… I won’t just let it slide. So basically, it’s not allowed when it comes to me.”

Many fans showed support for her.

“I’m not sure if it’s fear of failure or an obsession with perfection or what, but ppl are forgetting that the struggle to find the right words is a big part of what makes expressing love so meaningful. You didn’t know what to say? Good. Thank you for trying so hard anyway.” — just another boy

“its so nice hearing a kpop idol adamantly oppose ai usage” — *

“yujin scolding people for using ai thats my queen” — popo yujin’s onion
